Mark database
Responsibility mark search
Search for a responsibility mark by its letters or find makers associated with a particular location. You can use either field or complete both.
How to get better search results
If the holder of a responsibility mark is not found, try searching by location only. Results also include makers whose mark has not yet been identified with certainty.
For a Symbol Mark or Signature Mark, enter the Symbol Mark number or Signature Mark search code in the mark field. The codes are available in the Symbol Marks and Signature Marks sections above.
Letters in old marks can resemble one another. If necessary, try alternatives such as I and J, or C and G.
Enter the letters together without full stops or spaces: A:PIHRA → APIHRA, C:G:N → CGN and C.F. ELG → CFELG. The characters /, & and – may form part of a mark.
