Seafarer's Identity Document

The seafarer’s identity document is the internationally recognized identity record established by ILO Convention 185 of 2003, which revised the 1958 Convention 108. The biometric SID lets a seafarer transit borders for shore leave and crew change without a visa where the convention applies. It is distinct from the seaman’s discharge book, which records sea service, and complements the passport for the specific purpose of seafarer mobility.
