We now issue all original airmen certificates with a unique certificate number. The Airmen Certification Branch no longer assigns your Social Security Number (SSN) as your certificate number. If your certificate uses your SSN as the certificate number we will continue to issue you that number unless you request a unique number.
If your airman certificate uses your SSN as your certificate number and you would like to change it, or you would like to remove your SSN completely from our official records, please fill out a Request Change of Airmen Certificate Number (PDF, 19 KB) form. You can mail the completed form to:
Monday through Friday
7:30 a.m. to 4:00 p.m. Central Time
