Retire FAQ

Question
What are the CSA and CSF numbers? And, where did I get those CSA and CSF numbers?
Answer
When OPM receives your retirement application from your Agency, we mail you a Welcome Letter, along with a retirement card, which contains your CSA number.  It's a seven digit number and will be included on all correspondences from OPM. 

If you are a survivor, OPM will issue you a CSF number after we process the notification of death.  It, too, is a seven digit number and will be included on all correspondences from OPM. 

We will mail you a password which will give you access to your annuity online at Services OnLine.  You'll need your CSA (or CSF) and password in order to access the site. 

Remember:  When logging onto Services OnLine, follow the tips for entering your claim number in the logon box.

Retiree: If you are a retiree, the first letter you type in the claim number box is capital “A”, type your 7 digit claim number, then type in a zero.
Example: A12345670

Survivor: The first letter you type into the claim number box is capital “F”, type your 7 digit claim number, then type in a “W”.
Example: F1234567W
