What proves that the FCC has issued an operator/primary license grant?

The correct choice indicates that the presence of a license in the FCC ULS (Universal Licensing System) database serves as the official proof of an operator/primary license grant issued by the FCC. This database is the authoritative source for tracking amateur licenses and other telecommunications licenses in the United States.

When an individual passes the necessary examinations and the application is processed, the updated license information is reflected in the FCC ULS database. This serves not only as confirmation of the licensing status but also establishes the validity and legality of the operator to use the assigned call sign and operate on the amateur radio frequencies.

While a certificate of successful completion of examination or an email notification from the NCVEC may indicate that you have completed the necessary steps to obtain your license, neither of these documents is considered official proof of the license grant itself. The database listing is definitive evidence that the FCC recognizes the individual as a licensed amateur operator.
