TWIC card holders may renew their TWIC card online up to one year prior to the expiration date printed on their card and up to one year after their card expires. After one year, you will be considered a new enrollee, subject to the standard in-person enrollment process. To be eligible for online renewal, you must be a U.S. citizen, U.S. national, or a lawful permanent resident.
If you have changed your name since enrollment, you must contact the TSA Help Center at 855-DHS-UES1 (855-347-8371) to update your name before renewing online. If you are not eligible for online renewal, you can follow the same steps as a new applicant to renew your TWIC card in person at an enrollment center.
