1. Why use this guide?

Use this guide to interpret a range of abbreviations found in Merchant Navy service records from 1835 to 1972.

2. Essential information

You may need to interpret an abbreviation

  • so you can proceed to look at other possible records which may provide further information about the merchant seamen
  • because it will provide you with information about the merchant seamen  i.e. where they went on a particular recorded voyage

No key for port rotation numbers (which appear in earlier merchant seamen service records) has been found. You may be able to locate which official numbers belong to which ships in series BT 336.

4. Port numbers for UK ports

Use the below list to find out which port numbers abbreviations refer to which UK ports.

4.1 Why do I need to know which port numbers refer to which UK ports?

You may need to know which port number abbreviations refer to which ports so you can then proceed to find a document reference for an agreement and crew list from 1835 to 1857 in series BT 98

For more information on how to find an agreement and crew list read Crew lists, agreements and log books 1747-1861.

Port numbers frequently appear in merchant seamen records up to 1857. For information on where a port number may appear in a service record read Merchant seamen up to 1857: further research.
