Each radio service has its own rules for legal IDs: Ham, GMRS and more

If you have a license issued by the Federal Communications Commission to transmit, you’re required to say your call sign at regular intervals. It doesn’t matter whether you are a ham radio operator, a broadcast station, a business user or even public safety.
