Securing Your Importer Record: The CBP IRN Freeze Program

Protecting your business from unauthorized changes to your Importer Record Number (IRN) is critical for maintaining secure, compliant import operations. Participation in U.S. Customs and Border Protection’s (CBP) voluntary Freeze Program ensures that only designated, authorized individuals within your company can update your company’s name or address on record.
Why Enroll in the Freeze Program?
Enhanced Fraud Prevention: Restricts who can modify your IRN details with CBP.
Centralized Oversight: Once frozen, updates can only be processed by CBP’s Surety Bonds & Accounts Team (SBAT) upon receiving a CBP Form 5106 signed by your authorized representative.
Complete Control: You decide exactly which designated titles or positions hold updating authority.
How to Join or Leave the Program
To opt in or out, submit a formal request on company letterhead signed by an authorized importer of record or designated agent.
