Proof of Employment

USPS has joined more than 1,500 companies using The Work Number, an automated service that allows you to quickly — and securely — provide proof of your employment or income. You benefit from having control of the process, since you authorize access to your information. The Work Number can be used anytime, anywhere and its available 24 hours a day, seven days a week.


To verify employment, just give the verifier your social security number and the Postal Service employer code — 12946 — and send them to or have them call 1-800-367-5690.

    I worked for the US Postal Service from Sept 1969 to Sept 1973. Does the work number . com go back that far.
