Your Retirement Planning Checklist
Four to six weeks after retirement, OPM will send you a retirement claim number beginning with the letters “CSA” (Civil Service Annuity). You will need to refer to this number any time you call or write to OPM about your retirement or insurance benefits. Six to eight weeks after retirement, OPM will normally authorize interim annuity payments of approximately 80 percent of your estimated annuity until your retirement case is finalized.
