Where is the number to a border crossing card?

The number on a border crossing card, also known as a Border Crossing Card (BCC) or forma I-586, is typically found on the front of the card, usually located in the lower portion or near the cardholder's photograph. It is often labeled as the "Card Number" or similar designation. This number is unique to each cardholder and is used for identification purposes during border crossings. Always verify the specific layout, as it may vary slightly by issuing authority.
