Is BNC the Same as a Claim Number? A BNC is not the same as a claim number. Social Security uses your Social Security number for benefit claims. This number consists of nine digits and an alphanumeric suffix that identifies the type of beneficiary and their qualification category.

What is the BNC number?

The BNC is an encrypted 13-character alphanumeric code, which is unique to each notice. Employees access a lookup tool to identify the beneficiary and associated records. We also worked with the Department of the Treasury to remove the SSN from all Social Security and SSI benefit checks.

Where can I find my Social Security claim number?

Social Security claim numbers can be found on your Medicare card and on letters sent by SSA. You can contact SSA if you are not able to find our claim number.
