The Transportation Security Administration does not offer an address for sending applications for a Transportation Worker Identification Credential. Applicants can submit their details online by visiting TSA.gov or can visit an application center to complete the entire process in person.
Interested parties who complete an online application must also visit an application center to provide a facial photo, fingerprints and other required documentation such as a birth certificate and a driver's license or current U.S. passport. The application requires a non-refundable fee payable via money order, credit card, cashier's check or company check. Approved applicants can pick up the card at the application center or have the TSA mail it to their home address.
