Countries with a Merchant Navy or Merchant Marine require identifying credentials for their mariners. The 'Merchant Mariner's Document' (MMD) or 'Z-Card' in the United States, and the 'Ordinary Seaman's Certificate' in the Great Britain are examples of these credentials.

An Ordinary Seaman Certificate is a required certification to obtain a job as an Ordinary Seaman, a rating in a merchant ship's deck department. It consists mostly of proof of identity, proof of some minimal health (possibly including a drug test) and some minimal age, and the standards defined under Standards of Training, Certification and Watchkeeping for Seafarers (STCW).

United States

The 'Merchant Mariner's Document' (MMD), or 'Z-Card', is issued by the United States Coast Guard in accordance with the STCW guidelines, and is the standard documentation required for all crewmembers of U.S. ships with a Gross Register Tonnage of over 100. An entry-level MMD allows one to work on the deck as an Ordinary Seamen (OS), in the engine department as a Wiper, or in the steward's department as a Food Handler (FH). With experience and testing, qualified ratings such as able seaman (AB) or qualified member of the engine department (QMED) can be obtained.
The document is the size of a driver's license, and contains the sailor's information regarding date of birth, the location of issue, nationality, and the shipboard duties he or she is qualified for. Crewmen on any vessel over 100 gross tons are required to have one by United States law.
The documents were created shortly after World War II ended in 1945 to maintain security in ports around the world when sabotage was still a major concern. Today, the document still serves this purpose, and is regarded as a proof of identity as well as a passport when a sailor is in a foreign country. The document must be renewed every five years, and is obtainable by applying at any of the 17 United States Coast Guard Regional Examination Centers in the United States.
Prior to the early 1990s, Z-Cards were obtained free of charge and were good for life, but increased safety standards in the maritime industry sought to keep all active mariners renewing these documents and constantly training to stay abreast of any advancements in their field. All applicants for a Z-Card are required to apply, take a drug test, and wait for a criminal background check to complete before receiving their documents, which may take anywhere from a few weeks to 6 months.
The name Z-Card comes from its early days in use where the sailor's ID number always started with the letter 'Z'.
The Coast Guard has announced a proposal to replace the Merchant Mariner's Document, STCW Certificate, and Certificate of Registry with a new credential, the Merchant Mariner Credential. This proposal is related to the upcoming requirement for mariners to obtain a Transportation Worker Identification Credential.
