MEMORANDUM**


2
Arizona state prisoner Greg Schultz appeals pro se the district court's dismissal of his 42 U.S.C. § 1983 as frivolous under 28 U.S.C. § 1915(d).1  Schultz contends that a prison policy requiring that correspondence sent to an inmate include the inmate's prison number as part of the address violates his first and fourteenth amendment rights.   We have jurisdiction under 28 U.S.C. § 1291, and we reverse and remand.


3
We review the district court's determination that a complaint is frivolous under section 1915(d) for abuse of discretion.   Denton v. Hernandez, 112 S.Ct. 1728, 1734 (1992).   A complaint is frivolous if "it lacks an arguable basis in law or in fact."   Neitzke v. Williams, 490 U.S. 319, 325 (1989);   McKeever v. Block, 932 F.2d 795, 798 (9th Cir.1991).   In civil rights actions where the plaintiff appears pro se, the court must construe the pleadings liberally and afford the plaintiff the benefit of any doubt.   Karim-Panahi v. Los Angeles Police Dep't, 839 F.2d 621, 623 (9th Cir.1988).

"[W]hen a prison regulation impinges on inmates' constitutional rights, the regulation is valid if it is reasonably related to legitimate penological interests."   Turner v. Safely, 482 U.S. 78, 89 (1987).   If, however, the inmate can demonstrate alternatives to the regulation that accommodate the inmate's constitutional rights with minimal effect on valid penological interests, a court may consider such alternatives as evidence that the regulation does not satisfy the reasonable relationship standard.   Id. at 90.


5
Here, Schultz alleges that if correspondence addressed to him from outside of the prison does not have his inmate number on the envelope, it is automatically returned to the sender.   Such a policy arguably impacts first amendment rights of both inmates and non-inmates because it effectively blocks communication between them simply for failure to include the inmate's number.   Moreover, as far as we can tell on the scant record before us, the alleged policy may address purely administrative concerns rather than valid penological objectives.   See Turner, 482 U.S. at 89.   Accordingly, because it appears that Schultz's claim has an arguable basis in law, we reverse the district court's dismissal of the action, and remand for further proceedings.   See McKeever, 932 F.2d at 798.

REVERSED AND REMANDED.

 The district court dismissed the in forma pauperis complaint sua sponte before service of process.   We review this dismissal as a dismissal under 28 U.S.C. § 1915(d).   See Jackson v. Arizona, 885 F.2d 639, 640 (9th Cir.1989)
