OPM Retirement Services does not have a main fax number. You should only fax us documents if an official OPM form or one of our Customer Service Specialists asks you to (the fax number will be provided on the form, or the Customer Service Specialist will provide you one.) Otherwise, you should mail us your documents.
You can meet with one of our Customer Service Specialists in person. We serve walk-ins on a first come, first served basis—no appointment necessary. Retirement Services Support Center U.S. Office of Personnel Management 1900 E. Street, NW Room 1323 Washington, DC 20415 Directions. Hours: Monday thru Thursday, 8:00 a.m. to 4:00 p.m. ET
(However, hours for the Division of Retirement are 8 a.m. to 5 p.m. Eastern; 7 a.m. to 4 p.m. Central.) Employees living or traveling outside the U.S. can still use the toll-free number to contact the MyFRS Financial Guidance Line. You'll need to have an AT&T calling card or AT&T international network remote access to use the service.
