New Mailing Address Format for USCIS National Capitol Region Offices

WASHINGTON—U.S. Citizenship and Immigration Services (USCIS) announced today a new address format for offices within the National Capital Region (NCR), affecting all USCIS headquarters offices, the Arlington Asylum Office, and the Washington District Office.

In order to ensure the timely delivery of USCIS mail, correspondence addressed to the affected offices should list a unique mailstop and corresponding ZIP code + 4 number.    The mail will be delivered to each office according to the mailstop and ZIP code + 4 number provided.   If the address does not list a mailstop and corresponding ZIP code + 4 number, the correspondence will still be delivered but may be subject to minor delays as a result of the new mail process.

For example, the new format the Information and Customer Service Division, which handles all general inquiries, is:

Information and Customer Service Division MS 2260
U.S. Citizenship & Immigration Services
111 Massachusetts Ave. N.W.
Washington, D.C. 20529-2260

This address format change does not apply to USCIS offices outside the National Capitol Region (such as the Baltimore District). It also currently does not apply to the Alexandria Application Support Center.

Please see the attached list for the unique mailstop and corresponding ZIP code + 4 number of each affected office.
