, if you do not know your FCC Registration Number, look yourself up on:
and there will be an entry towards the bottom that says "FCC Record #" and a button that says "View FCC Record" that will take you to your record. If you have never logged in to the FCC's Universal Licensing System (ULS) website, go ahead and register. It is very easy to update your license, renew your license, etc. via the ULS portal.
If you have any questions, let us know.
