CBP Discontinuing 5106 Mailbox

Trade Update • August 11, 2021

U.S. Customs and Border Protection Agency has advised that the Office of Trade’s Commercial Operations Revenue and Entry Division (CORE) will be disabling the 5106 mailbox, effective September 4, 2021.

CBP 5016 is the form used to create or update importers’ unique identification information within CBP’s systems. The Agency is currently in the process of revising the form and incorporating those changes into the Automated Commercial Environment.

New Procedure for Submitting 5106 Requests

All future Form 5106 requests must be sent to the appropriate location as indicated below:

• Center of Excellence and Expertise – If the importer has been assigned to a Center, send requests to the corresponding Center email address.
• Port of Entry – If the importer has not been assigned to a Center, go here to determine the port location to which the request should be submitted.
• Revenue Division – If the importer is in void status, inquiries should be sent to bondquestions@cbp.dhs.gov, using the naming convention Void IR#, in the subject line.

Note: Do not send requests to multiple locations since this will cause duplication of work and delayed processing.

How Do I…?

Make a New Request: A completed and signed CBP Form 5106 should be emailed to the appropriate Center of Excellence and Expertise. The subject of the message should include “New 5106 Add.” Center email addresses can be found here.

Update My Address: To update your address, you will have to complete a new CBP Form 5106. The completed and signed CBP Form 5106 should be emailed to the appropriate Center of Excellence and Expertise. The subject of the message should include “5106 Update” along with the team assignment of the account so that it can easily be routed to the appropriate division.
