                              OPINION

PER CURIAM:

   On February 23, 1999, Jeffrey Alan Wright pleaded guilty to two
counts of a three-count indictment: possession with intent to distribute
cocaine, in violation of 21 U.S.C.A. § 841(a)(1) (West 1999), and
felon in possession of a firearm, in violation of 18 U.S.C.A. § 922(g)
(West 2000).1 The United States District Court for the District of
South Carolina sentenced Wright to 204 months imprisonment for
violation of § 841(a)(1) and to 120 months imprisonment for violation
of § 922(g), to run concurrently. Wright appeals this sentence, argu-
ing that the district court improperly applied a sentencing enhance-
ment under § 841(b)(1)(A) for a prior felony drug conviction. For the
reasons that follow, we affirm the sentence imposed by the district
court.

                                   I.

   On September 2, 1998, the Drug Enforcement Administration
received a tip that Wright, a suspected cocaine distributor in Sumter
County, South Carolina, was in possession of cocaine and a firearm.
Officers observed Wright driving away from his business, despite
having a suspended driver’s license. The officers stopped Wright,
who gave oral and written permission to search his vehicle. The offi-
cers found one kilogram of cocaine powder and a firearm in the vehi-
cle and arrested Wright. Pursuant to a search warrant, authorities
    1
   The government dismissed the third count in exchange for Wright’s
guilty plea.
                         UNITED STATES v. WRIGHT                           3
searched Wright’s place of business and seized four kilograms of
cocaine powder found therein. Wright’s indictment, plea agreement,
conviction, and sentencing followed.

   In the plea agreement, Wright stipulated to distributing between
five and fifteen kilograms of cocaine powder. Under 21 U.S.C.A.
§ 841(b)(1)(A), the appropriate sentence for a conviction based upon
possession of five to fifteen kilograms of cocaine powder is ten years
to life. 21 U.S.C.A. § 841(b)(1)(A) (West 1999). That section, how-
ever, requires the district court to enhance the statutory range to
twenty years to life when the defendant has a prior felony drug con-
viction. Id.

   Wright was convicted of two separate prior felony drug offenses in
1987 and 1991, respectively. For the mandatory sentencing enhance-
ment of § 841(b)(1)(A) to apply, however, the government must com-
ply with the provisions of 21 U.S.C.A. § 851 (West 1999 & Supp.
2000), which require the government to file and serve an information
indicating its intent to seek an enhanced penalty for a prior conviction.2

  On February 17, 1999, five days prior to the execution of the plea
  2
   The pertinent section of § 851 states as follows:
      Proceedings to establish prior convictions
      (a) Information filed by United States Attorney
         (1) No person who stands convicted of an offense under this
      part shall be sentenced to increased punishment by reason of one
      or more prior convictions, unless before trial, or before entry of
      a plea of guilty, the United States Attorney files an information
      with the court (and serves a copy of such information on the per-
      son or counsel for the person) stating in writing the previous
      convictions to be relied upon. Upon a showing by the United
      States Attorney that facts regarding prior convictions could not
      with due diligence be obtained prior to trial or before entry of a
      plea of guilty, the court may postpone the trial or the taking of
      the plea of guilty for a reasonable period for the purpose of
      obtaining such facts. Clerical mistakes in the information may be
      amended at any time prior to the pronouncement of sentence.
21 U.S.C.A. § 851 (West 1999 & Supp. 2000).
4                       UNITED STATES v. WRIGHT
agreement, the government filed and served Wright’s two attorneys
with an information specifying its intent to seek an enhanced penalty
for the 1991 conviction. Two days later, the government filed and
served Wright’s attorneys with another information specifying its
intent to seek an enhanced penalty for the 1987 conviction. On Febru-
ary 22, 1999, Wright entered into and signed a written plea agreement
in which the government agreed to forego the enhancement relating
to his 1987 drug conviction and to seek the enhancement based only
upon Wright’s 1991 drug conviction.

  At the sentencing hearing, despite having signed the plea agree-
ment in which Wright agreed to the use of his 1991 conviction as a
sentencing enhancement, Wright argued that the prior conviction was
not a felony drug conviction that could be used as such an enhance-
ment. Wright’s attorney further argued that he had not been served
with the information, as is required under 21 U.S.C.A. § 851. Upon
questioning, counsel conceded that, although neither he nor his co-
counsel had actually received the information, they both had actual
notice of its contents and of the government’s intended use of
Wright’s 1991 prior conviction.

   The district court held that Wright’s 1991 conviction qualified as
a felony drug conviction sufficient to invoke the mandatory minimum
enhancement in 21 U.S.C.A. § 841(b)(1)(A). Additionally, the gov-
ernment produced a certificate of service demonstrating that it had
served the information on Wright’s counsel. Because Wright’s coun-
sel produced no evidence, other than the alleged non-receipt of the
information, rebutting the presumption that the information had in
fact been served, the district court found that the government met its
burden of proving that it had served the information. Pursuant to the
plea agreement, the government moved for a thirty six-month down-
ward departure for substantial cooperation from Wright’s twenty-year
sentence, which the district court granted. Wright appeals his sentence
and argues that the district court should not have applied the twenty-
year mandatory minimum to his sentence.

   On appeal, Wright first argues that he did not receive a copy of the
information, which he alleges indicates that the information was not
served in accordance with 21 U.S.C.A. § 851.3 Assuming that the
    3
   Wright further argues that the lack of proper service is a jurisdictional
defect. Given our agreement with the district court’s holding that the
                        UNITED STATES v. WRIGHT                          5
information was served, Wright argues that the district court neverthe-
less improperly enhanced his sentence because the 1991 conviction
was neither a "conviction" nor drug-related and, therefore, does not
trigger the § 841(b)(1)(A) enhancement provision.4 We will address
each argument in turn.

                                    II.

   Wright argues that the district court improperly found that the gov-
ernment served the 1991 prior conviction information. Wright con-
cedes that, if the information had in fact been placed in the mail, that
mailing would constitute sufficient service, irrespective of his non-
receipt. He contests, however, if the United States Attorney’s office
actually placed the information in the mail. The issue of whether the
United States Attorney’s office actually placed the information in the
mail is a question of fact. "If the court’s [factual] findings may ratio-
nally be said to be supported by a preponderance of the evidence, they
may not be disturbed on appeal." United States v. Crump, 120 F.3d
462, 468 (4th Cir. 1997).

   Proper service by mail is governed by Federal Rule of Criminal
Procedure 49, which states that service must comply with the rules
"provided in civil actions." Fed. R. Crim. P. 49(b). Federal Rule of
Civil Procedure 5(b) provides that "service upon the attorney or upon
a party shall be made by delivering a copy to the attorney or party or
by mailing it . . . at the attorney’s or party’s last known address. . . .
Service by mail is complete upon mailing." Fed. R. Civ. P. 5(b).
Because service is complete upon mailing, non-receipt of the informa-
tion does not affect the validity of service. See, e.g., In re Eagle Bus.
Mfg. Inc., 62 F.3d 730, 735 (5th Cir. 1995) ("[T]he question becomes
whether the sender properly mailed the notice and not whether the
intended recipient received it."); see also Charles Alan Wright &
Arthur R. Miller, Federal Practice and Procedure § 1148 at 430-

information was served in accordance with § 851, we have no occasion
to pass upon the district court’s alternative holding that service is not a
jurisdictional requirement under § 851.
   4
     Wright does not dispute that the information was filed properly; he
argues only that the information was not served.
6                      UNITED STATES v. WRIGHT
31(1987 & Supp. 2000) (citing cases holding that service is complete
upon mailing regardless of non-receipt). Accordingly, the central
issue in determining whether the information was served is whether
the information was placed in the mail and not whether Wright’s
counsel received the information.

   The burden of showing that service was made is on the serving
party, which in this case is the government. See Rivera v. M/T Fos-
sarina, 840 F.2d 152, 155 (1st Cir. 1988). The evidence in the record
supports the district court’s conclusion that the information was actu-
ally mailed. First, the government introduced into evidence a signed,
valid certificate of service stating that both of Wright’s attorneys were
served "by placing said copies in a postpaid envelope" addressed to
each of them at their respective addresses. (J.A. Supp. I at 2). A pre-
sumption that the information actually was mailed attaches to this
valid certificate of service. See Fed. R. Civ. P. 5(d), Advisory Com-
mittee Notes, 1991 amendment (stating that certificates of service are
required to be on file because they "may be useful for many purposes,
including proof of service if an issue arises concerning the effective-
ness of the service"); Eagle, 62 F.3d at 735-36 (stating that a court
should look to whether a proper certificate of service was filed to
determine whether mailing took place); Wright & Miller, supra,
§ 1150 at 436-37 (approving of allowing the certificate of service to
constitute sufficient proof of service because that approach "avoids
delayed challenges to service and frivolous appeals"); cf. Timmons v.
United States, 194 F.2d 357, 361 (4th Cir. 1952) (holding that attor-
ney’s certificate of service is sufficient to establish service in the
absence of any requirements as to the form of proof and of a season-
able objection).

   Additionally, at sentencing, the Assistant United States Attorney
stated that her office had "complied with the [office’s] standard pro-
cedure" by filing the information and the certificate of service and
proceeding to mail the information to Wright’s counsel. (J.A. at 18).
The district court did not err by accepting the certificate of service
and the statement of the Assistant United States Attorney as proof that
the information was mailed without requesting an affidavit from that
office as further proof of actual mailing. As noted in Timmons,

    The addition of an affidavit would perhaps have given a
    greater appearance of formality, but it would have added
                       UNITED STATES v. WRIGHT                        7
    nothing to the effect of the certificate [of service] since it
    would constitute merely a voluntary act of the affiant; and
    the absence of the affidavit did not absolve the certifier from
    the criminal sanctions applicable to one who corruptly
    obstructs the administration of justice in the federal courts.

Timmons, 194 F.2d at 361 (citing 18 U.S.C.A. § 1503).

   The record further reflects that Wright’s counsel had changed
addresses without notifying the government. When an improper
address is given, a delay in receipt of items properly placed in the
mail is expected. Based upon this change of addresses without notifi-
cation to the government, the record supports an inference that the
information had been placed in the mail but failed to reach counsel
in a timely fashion. Cf. Eagle, 62 F.3d at 736 ("Moreover, we note
that Rogers herself is to blame for not receiving the notice because
she failed to keep Greyhound apprised of any changes in her mailing
address.").

   Wright’s only evidence contradicting the government’s proof of
actual mailing is his counsel’s in-court statement that neither he nor
his co-counsel received the information. As stated above, however,
non-receipt does not affect the validity of service. If we accept coun-
sel’s mere denial of receipt as conclusive evidence that the informa-
tion was not mailed, we would implicitly rewrite Rule 5 to require
receipt to validate service. See Fed. R. Civ. P. 5(b) ("Service by mail
is complete upon mailing."); see also Eagle, 62 F.3d at 735-36 (stat-
ing that a denial of receipt is insufficient to rebut a presumption that
actual mailing occurred). We decline to extend Rule 5’s service
requirement in this way. To the extent, however, that counsel’s state-
ments have any evidentiary value toward the issue of whether the
information was placed in the mail, that evidentiary value is offset by
the valid certificate of service and the Assistant United States Attor-
ney’s statement that her office had complied with its standard proce-
dure by placing the information in the mail.

  In light of these facts, it was not clearly erroneous for the district
court to conclude that the government met its burden of proving ade-
quate service. Accordingly, we affirm the district court’s factual find-
8                       UNITED STATES v. WRIGHT
ing that the government complied with the requisites of § 851 by
mailing the information to Wright’s counsel.

                                   III.

   Wright next argues that the district court erred by determining that
Wright’s 1991 conviction qualified as a prior felony drug conviction
for the purpose of enhancing his sentence under § 841(b)(1)(A).5 Spe-
cifically, he argues that his plea of nolo contendere to his 1991
offense was not a "conviction" under Florida law. Wright further
argues that his 1991 offense was not drug-related because he was
charged and convicted under a general conspiracy statute. We address
each argument in turn.

   When a defendant objects to the court’s treatment of one of his
prior convictions as a particular type of crime for sentencing pur-
poses, we review the issue de novo. See United States v. Kirksey, 138
F.3d 120, 122 (4th Cir. 1998). The government has the burden of
proving beyond a reasonable doubt that the alleged underlying con-
viction is a prior felony drug conviction for purposes of enhancement
under § 841. 21 U.S.C.A. § 851(c)(1) (West 1999 & Supp. 2000).
Because we hold that the government is able to meet this burden of
proof, we affirm the district court’s determination that Wright’s 1991
    5
   The government urges us to decline to review these arguments
because Wright failed to file a written response to the information, as is
required under § 851(c)(1). Despite Wright’s failure to file a formal writ-
ten response, however, the government allowed the district court to con-
duct an evidentiary hearing on Wright’s objections to his prior conviction
and did not object to Wright’s failure to file a written response. Accord-
ingly, the government has waived the issue of Wright’s non-compliance
with § 851 by its failure to notify the district court of his non-
compliance. Cf. United States v. Brown, 33 F.3d 1014, 1017-18 (8th Cir.
1994) (declining to consider the defendant’s argument waived for failure
to comply with the written response requirement of § 851 because the
district court had addressed the argument on its merits); United States v.
Stephens, 35 F.3d 451, 453-54 (9th Cir. 1994) (holding that because the
government did notify the district court of the defendant’s failure to com-
ply with the written response requirement of § 851, the government was
not barred from asserting that lack of compliance on appeal).
                       UNITED STATES v. WRIGHT                          9
conviction qualified as a felony drug conviction to warrant sentencing
enhancement under § 841.

                                   A.

   Wright contends that his 1991 plea of nolo contendere is not a
"conviction" under Florida law, see Garron v. Florida, 528 So.2d
353, 360 (Fla. 1988), and, therefore, an enhancement under
§ 841(b)(1)(A) is not warranted.6 We have, however, previously
rejected the argument that state law controls the definition of "convic-
tion" as that term is used in § 841.7 See United States v. Campbell,
980 F.2d 245, 250 n.6 (4th Cir. 1992) ("Interpretation of the ‘final
conviction’ language used in section 841 is a matter of federal, rather
than state, law because it involves a federal statute."). Thus, Florida’s
failure to treat a plea of nolo contendere as a conviction is irrelevant
to our determination of whether Wright’s 1991 nolo contendere plea
constitutes a conviction for purposes of a sentencing enhancement
under § 841. The issue, rather, is whether the plea of nolo contendere
is a prior conviction as that term is defined under federal law.

   We had occasion to define the meaning of "conviction" as the term
is used in § 841 in Campbell, in which we held that a sentence of pro-
bation, entered without an adjudication of guilt, was a "conviction"
for purposes of § 841. See id. at 250-51. We did not address, however,
whether a plea of nolo contendere is outside the scope of "conviction"
as the term is used in § 841.

  In resolving this issue, we are guided by the United States Supreme
Court’s prior analysis of the meaning of "conviction." In defining
"conviction," the United States Supreme Court has focused on the text
  6
     Wright argues the applicability of Florida law to the definition of
"conviction" because his 1991 arrest and conviction took place in Dade
County, Florida.
   7
     Even if we applied Florida law to determine the meaning of convic-
tion, Garron v. Florida, 528 So.2d 353, 360-61 (Fla. 1988), would not
aid Wright because that case held that a plea of nolo contendere, where
adjudication was withheld, is not a "conviction" for purposes of a capital
sentencing proceeding. Wright’s adjudication was not withheld. See infra
at 14. Accordingly, Garron is inapplicable to Wright’s offense.
10                      UNITED STATES v. WRIGHT
of the statute and the entry of judgment and sentencing to determine
whether a prior offense constitutes a "conviction." See Dickerson v.
New Banner Inst., Inc., 460 U.S. 103, 110-15 (1983) (defining "con-
viction" in the context of 18 U.S.C.A. § 922(g) and (h), which pro-
hibit a "convicted" felon from possessing a firearm). In Dickerson, the
Supreme Court reasoned that a plea of guilty to a kidnapping charge
resulting in a deferred probationary sentence was nevertheless a "con-
viction" under § 922. See id. at 114. The Court stated that although
the definition of "conviction" may vary according to its use in differ-
ent federal statutes, the entry of formal judgment typically establishes
that the prior plea was a "conviction," absent language in the relevant
statute defining "conviction" more narrowly. See id. at 113 n.6. The
Court distinguished Lott v. United States, 367 U.S. 421 (1961), in
which the Supreme Court had held that a plea of nolo contendere was
not a "conviction" because it had not resulted in the entry of final
judgment and was being reviewed within a time frame in which the
defendant had the ability to withdraw the plea. See Dickerson, 460
U.S. at 113 n.7. From its discussion of Lott, the Court made clear that
the relevant inquiry in defining the term "conviction" is not the nature
of the plea entered by the defendant but rather the entry of final judg-
ment of guilt and the imposition of a sentence indicating the defen-
dant’s guilt. See id.

   Although Wright entered a plea of nolo contendere, the state circuit
court for Dade County, Florida, formally entered judgment of guilt
against Wright and sentenced him to time served, two years proba-
tion, and a $225 fine.8 Additionally, as with § 922, the text of § 814
  8
   Wright argues that no formal adjudication was entered against him,
but his argument is unavailing because the state court’s order of proba-
tion contains separate sections for "Judgment of Guilt" and for "Order
Withholding Adjudication." (J.A. at 51G). The state court completed the
section for "Judgment of Guilt" and sentenced Wright under that section
to time served, two years of probation, and a $225 fine, whereas it left
blank the section for "Order Withholding Adjudication." It is clear, there-
fore, from the state court’s order that the state court entered judgment
against Wright. Regardless, however, of whether adjudication was
entered against Wright, his sentence of probation indicates that he was
convicted. See Dickerson v. New Banner Inst., Inc., 460 U.S. 103, 113-
14 (1983) ("[O]ne cannot be placed on probation if the court does not
deem him to be guilty of a crime. . . ."); see also United States v. Mejias,
47 F.3d 401, 404 (11th Cir. 1995) (holding that a plea of nolo contendere
to a state felony charge constitutes a conviction for purposes of § 841,
despite the fact that adjudication was withheld).
                       UNITED STATES v. WRIGHT                       11
does not indicate any congressional intent to limit the scope of the
term "conviction" within that statute so as to exclude those pleas that
result in the entry of a formal judgment. Accordingly, under the
Supreme Court’s reasoning in Dickerson and our holding in Camp-
bell, we hold that the district court correctly concluded that Wright’s
1991 plea of nolo contendere, which resulted in the entry of a formal
judgment of guilt and a sentence of time served, two years probation,
and a $225 fine, constitutes a "conviction" as that term is used in
§ 841.

                                  B.

   Finally, Wright argues that the evidence presented at sentencing
was insufficient to prove that his prior conviction was drug-related
and, therefore, an enhancement under § 841 is not warranted. Wright
contends that he was charged and convicted under a general conspir-
acy statute. Because a general conspiracy offense does not include a
drug component as an element of the offense, Wright argues that his
conspiracy conviction is not drug-related. Wright’s argument that he
was charged and convicted only under the general conspiracy statute
and not a drug-related statute ignores all of the charging and convic-
tion documents in the record. The amended information charged
Wright with conspiracy to traffic in cocaine in violation of Fla. Stat.
Ann. §§ 777.04 and 893.135. Section 777.04 is a general conspiracy
statute, whereas § 893.135 makes drug-trafficking a "felony of the
first degree." Similarly, the order of probation states that Wright
entered a plea of nolo contendere to the offense of "conspiracy to traf-
fic drugs." (J.A. at 51G). Accordingly, we find no support in the
record for Wright’s allegation that he was not convicted of a drug-
related offense. Thus, we uphold the district court’s determination
that the government produced sufficient evidence of Wright’s prior
felony drug conviction to warrant the § 841 sentencing enhancement.

                                  IV.

   In conclusion, we reject Wright’s various arguments that a sentenc-
ing enhancement under § 841 for his prior felony drug conviction was
not warranted. For the reasons stated, we affirm Wright’s sentence.
