When we receive your retirement application, we will notify you and will provide a civil service claim identification number (a seven-digit number preceded by "CSA"). You must use that identification number whenever you contact OPM about your annuity. To check the status of your form or application, you may contact the Retirement Office at (888) 767-6738 or
retire@opm.gov. The phone lines are open from 7:30 am to 7:45 pm (Eastern Standard Time). It is a busy phone number so we encourage you to call early in the morning or after 5:00 pm when the phone lines are less busy.
