What filer code DEF means

CBP issues one three-character filer code per permitted brokerage company. Every entry Mark III International CHB Inc transmits carries DEF as the first three characters of its entry number, which is how CBP and the importer trace a given entry back to the firm that filed it.

That makes the code more reliable than the name for identification. Firm names in the CBP list are truncated, inconsistently punctuated, and sometimes shared across separate permits, whereas the filer code is unique. If you are reconciling entry summaries or a CBP notice against a broker, match on DEF.

To file at all, the company must hold a customs broker permit and employ at least one individually licensed customs broker who qualifies it. The permit is national in scope, so Mark III International CHB Inc is not restricted to filing at ports near Jamaica.
