Log in to the ULS License Manager with your FCC registration
number (FRN) and CORES password to view and manage your
licenses and applications. The sections of this document
contain help for common issues related to logins and FRNs.
If you have forgotten your CORES password, please call FCC Technical Support at 1-877-480-3201.
Effective 7/15/2022 at 6 pm ET, Legacy CORES is no longer accessible.
All FRN registrations and updates, including FRN password resets, must be completed in the new
CORES.
Users who do not have an FCC username will need to register a username in the FCC User Registration System and associate their FRN(s) in CORES.
An FRN, or FCC registration number, is a 10-digit number
that is assigned to all businesses and individuals conducting
business with the FCC. The FCC will use the FRN to determine
if all of a registrant's fees have been paid. You must register
with the Commission prior to filing applications in ULS
License Manager. You may already haven an FRN. Most ULS
and ASR users that had existing licenses and were registered
in the ULS TIN Registration database prior to December 3,
2001, were issued an FRN automatically. Search by your call
sign in ULS License Search. Your FRN will appear on the
License Search results page.
For more information, see Public
Notice DA 01-2452.
You must have an FCC Registration Number (FRN) to transact
business with the FCC, including filing applications online
with ULS. Most ULS and ASR users registered in the ULS TIN
Registration database, prior to December 3, 2001, who
had existing licenses were automatically assigned an FRN
by ULS. As a result, you may have already received one or
more FRNs. At the time of the conversion, each TIN/SGIN
combination received a corresponding, separate FRN.
For more information see Public
Notice, DA 01-2452
or and the FAQ on the CORES
website
A unique FRN is assigned to each registrant (using the
tax payer identification number or TIN). If you register
again, another FRN will be assigned to you. You may have
a good reason to obtain multiple FRNs. For example, the
state of Virginia has a single TIN; however, individual
departments and agencies of the state government that transact
business with the FCC have been assigned unique FRNs. In
another example, a corporation may choose to request a separate,
unique FRN for each division, department, or line of business.
It is possible you have received multiple FRNs inadvertently.
If you had an existing license and were registered in the
ULS TIN Registration database prior to December 3, 2001,
you may have been automatically assigned an FRN. If you
have subsequently registered with CORES, you may now have
multiple FRNs.
You cannot cancel an FRN. However, you may ask the CORES
Help Desk to deactivate an FRN that is not associated with
a license (call sign) in ULS. The deactivated FRN may be
used within the FCC for statistical purposes.
If you have multiple FRNs registered to the same TIN, and
you would like to associate a license currently assigned
to one of your FRNs to a different FRN associated with your
TIN, you may contact ULS Technical Support to request this
change. The process will be greatly expedited if the person
contacting Technical Support is the same person listed as
the contact person on the license. The Help Desk may request
additional proof by fax or US mail that the person making
the request is the legitimate licensee before processing
the request. Use the link in the bottom right of the ULS
license manager to view the contact information for ULS
Technical Support.
