What is the Commission Registration System?
Before you can take advantage of all of these new features, first you
must register! The vehicle for doing this is the Commission Registration System (CORES). For many amateurs, ULS and CORES may be transparent, especially for those filing electronically, but they are two different systems. Registration involves simply entering your Taxpayer Information Number (typically your Social Security Number), your name and your call sign (or call signs if you hold any in other FCC Wireless Telecommunications Bureau-administered services) into the ULS.
Amateurs may now file electronically overthe FCC ULS Web Site. Manual filing using the paper form remains, but people are encouraged to file electronically which is easier.
