Yes, you will receive a physical Global Entry card in the mail after you are approved for the program, but it is rarely needed for air travel. When arriving in the United States by air, the card is not required; instead, you simply use the facial recognition kiosks or the Global Entry mobile app. The physical card is primarily designed for land and sea border crossings when entering the U.S. from Canada or Mexico via NEXUS, SENTRI, or "Ready Lanes." It serves as a valid form of federal photo identification and is RFID-enabled to allow for expedited processing at vehicle checkpoints. To receive the card, you must be a U.S. citizen, a U.S. lawful permanent resident, or a Mexican national. If you are a citizen of another country (like the UK or Germany) enrolled in Global Entry, you will not receive a physical card. For air travelers, the most important part of your approval is the Known Traveler Number (KTN), which you must add to your airline profile to receive TSA PreCheck benefits.
