The FCC has decided to end Legacy CORES and has online the new CORES2. 

Every Licensee should register with CORES2 to continue to be able to manage their FRN after July 15th, 2022. 
It is important that you do this and also affiliate your FRN with your new login on CORES2. 

Failure to do so by July15th will require you to contact the FCC to make any changes. 

CORES is the database that lists your Personal name, address, email and phone number and the FRN with the FCC.   

The Licenses you hold are in the ULS (Universal License System).   They work together.

CORES access info is below and the ULS can be accessed at this URL if you need it.

See the FCC NOTICE below for information.

DA 22-508

MD Docket No. 10-234

The Office of Managing Director will decommission the Federal Communications Commission (FCC or Commission) Legacy Commission Registration System (CORES) (Legacy CORES) on July 15, 2022.

The current version of CORES (called CORES2 herein and found at has been in use since 2016 and should be used to register for or maintain an FCC Registration Number (FRN).

2 Using CORES2 for FRN-related transactions requires FRN registrants to set up an account with a unique username (by providing a valid e-mail address)

3 and password to associate with their existing or new FRN(s).

4 The FRN registrant’s email address is then established in the system as their username. Users already registered in CORES2 can continue to manage their FRNs in CORES2 without change. No additional actions are required for CORES2 users.

Legacy CORES will be retired on July 15, 2022 at 6 pm.

5 Once Legacy CORES is retired, users will be unable to make any changes to their FRNs in that system, including resetting their passwords. Users should be aware that they will need to register in CORES2 to gain online access and manage their FRN(s). See below for help with FRN registration in CORES2.

1 Commission rules require an FCC Registration Number (FRN) to be supplied by anyone doing business with the Commission. 47 CFR. § 1.8002. Any business or individual wishing to conduct business with the Commission must register through CORES to obtain an FRN. 47 CFR. § 1.8001. The FRN is a 10-digit number used to identify the registrant’s business dealings with the Commission. Id.

2 CORES2 allows users to (1) Create FRNs; (2) Modify FRNs; (3) Associate FRNs to different user accounts; (4) View FRN financial data; and (5) Make payments. See also

3 To finalize the decommissioning of Legacy CORES, the Commission updated 47 CFR 1.8002(b) to require registrants to provide a valid e-mail address when registering for an FRN through CORES. Amendment of Part 1 of the Commission’s Rules, Concerning Practice and Procedure, Amendment of CORES Registration System, MD Docket No. 10-234, Report and Order, 36 FCC Rcd 10773 (2021) (CORES Order); Federal Communications Commission, Practice and Procedure, CORES Registration System, 86 Fed. Reg. 59858 (Oct. 29, 2021).

5 The Commission directed the Office of Managing Director to announce the end date for access to Legacy CORES. CORES Order, para.11.

Federal Communications Commission DA 22-508

Recommended steps prior to July 15th To help prepare for any upcoming Commission business, Legacy CORES users are encouraged to establish an FCC username account in the FCC User Registration System, and then to access CORES2 to associate their FRN(s) with their username. Legacy CORES should not be used for creating new FRNs even though it will remain open through July 15, 2022.

The Commission is in the process of transitioning its various online systems to CORES2.

Certain Commission systems already require access using a username and password that have been registered in the FCC User Registration System and associated with FRN(s) in CORES2. Other Commission systems will continue to allow access using the FRN and password established in the Legacy CORES. Users may also log in to these systems using an FRN and username password, established in CORES2. Over time, Commission systems that have not yet transitioned will be updated to require a username and password obtained through the FCC User Registration System and may redirect users to use CORES2 to associate their FRN(s) with a valid FCC username. Future system transitions will be handled at different timeframes through separate notifications.6

Payment and Payment-Related Transactions Users that need to pay annual regulatory fees, view Red Light status details, pay Universal Licensing System (ULS) fees, and complete payments for all FCC filings and fees will be required to use a username and password with an FRN associated with a username in CORES2 to authorize these transactions according to the following timetable:7
