- Acceptable Evidence for Identification - According to CFR Title 46 part 10.203(d):
"Although an MMD and an MMC serve as certificates of identification, a TWIC must be retained by the mariner to whom it was issued and, while valid, serves as the mariner's primary identification document. The TWIC must be produced to verify identity when required by an authorized official as identified in 33 CFR 101.515(d). "
Transportation Worker Identity Credential (TWIC)
Mariners who desire to send correspondence or applications to a Regional
Examination Center, should use the correct address (available here)

ensure that a return address is shown on the envelope. Incorrectly addressed
mail will result in delays in processing. If sending original or certified
copies of documents, it is recommended that you use certified mail or another
mail service that provides tracking capabilities. Originals will be returned
to you after verification.
