UPDATED: Keep Your FRN Information Up to Date

February 9, 2026

As we flagged on February 6, new rules took effect on February 5, 2026, requiring any entity or individual with an FCC Registration Number (FRN) to update their FRN contact information in the FCC’s Commission Registration System (CORES) within 10 days of any change to such information. This new 10-day requirement was coupled with a rule change imposing a fine of $1,000 per day on parties subject to submitting filings in the Robocall Mitigation Database (RMD) who fail to update their information within 10 days of a change. 

These overlapping rule changes led some to believe that the $1,000 daily penalties applied to all CORES registrants, not just RMD filers. In a Public Notice released February 6, 2026, the Wireline Competition Bureau made clear that while all CORES registrants are required to update their FRN information within 10 days of a change, the $1,000 per day fine applies only to RMD filers. Outside of the RMD context, the FCC has not identified a specific base forfeiture amount or method of calculation for failing to update FRN contact information in a timely manner.

Each person or entity that does business with the FCC must obtain an FRN. This includes not only those who hold an FCC license or authorization, but also any individuals or entities with reportable interests in such licensees or authorization holders, as well as those who may have other FCC-related reporting requirements. When an entity requests an FRN, it must provide its name, contact information, and Employer Identification Number (EIN). When an individual requests an FRN, they must provide their Social Security number in addition to their name and contact information.

In view of the new 10-day requirement, we encourage all parties with an FRN to periodically check their FRN contact information in CORES to confirm it is accurate and up to date. To check the information associated with an FRN, you must first log in to CORES. New FRNs can be obtained here. Prior to obtaining a new FRN, you must first set up a CORES username.
