28 Miss. Code R. § 1-02-207
In accordance with the U.S. Coast Guard 33 Code of Federal Regulations 101.514, all persons requesting unescorted access to secure areas of facilities regulated by the USCG must possess a Transportation Worker Identification Credential (TWIC) or request must be denied. Persons requesting access to the Mississippi State Port Authority at Gulfport facilities and who has been approved for access but does not possess a TWIC card must have an approved TWIC Escort. Such escorting must be side-by-side for the duration of the visit.
Although the Mississippi State Port Authority encourages each person requesting access into the Port to possess a TWIC we realize that access may be required while the TWIC application is being processed so the Mississippi State Port Authority at Gulfport has licensed three (3) TWIC Escort companies to conduct the side-by-side escort service. You may contact Americas Security Escort Service at (985) 385-2737, U.S. Maritime (251) 459-1578 or Gartman Security Escort Service at (228) 234-2043 for your Port access requirements.
