How long is a TWIC valid once issued?

The Transportation Worker Identification Credential, commonly known as TWIC, is typically valid for a period of five years from the date of issuance. After this period, workers will need to renew their TWIC to maintain their access to secure areas of the maritime transportation system. It is important to note that starting the renewal process before the expiration date is advisable, as it can help avoid any disruptions in employment or access. The renewal application can often be completed online, and further details about the process can usually be found on the official TWIC website. Keeping track of the expiration date is essential to ensure that you maintain your credential without any gaps in validity.
