Your CalPERS ID Number Explained

" "

Your CalPERS ID is a unique identifier you can use when contacting us or completing any CalPERS business transactions.

CalPERS is committed to protecting your confidential member information. One step we have taken is to assign each CalPERS member a unique 10-digit identifier, which we refer to as the CalPERS Identification Number, or CalPERS ID.

Use your CalPERS ID as an alternative to your Social Security number when conducting any CalPERS business. For example, you can use it to identify yourself when registering for my|CalPERS or when calling our CalPERS Customer Contact Center. You can also use it when completing CalPERS forms and business transactions.

In fact, we encourage members to note their CalPERS ID on any and all correspondence with CalPERS. For example, whether you submit a letter or copy of a marriage certificate, simply write your CalPERS ID at the top of the page.

Your CalPERS ID will stay with you as your working status changes. Whether you retire or switch to another employer, your CalPERS ID will always remain the same.

If you don’t yet know your CalPERS ID, here are a few ways to find it:
