The Department of Defense Commercial and Government Entity (DOD CAGE) code identifies the manufacturer of the part or product, sometimes  produced under government contract .  CAGE codes are also used by civilian organizations to provide a standardized method of identifying a given facility at a specific location which can aid in the traceability of Aviation parts.

CAGE Codes are used by Boeing both internally and on their MyBoeingFleet product when referencing suppliers.

CAGE Codes are used internationally as part of the NATO Codification System (NCS), and are sometimes refered to as  NCAGE Codes. CAGE codes are referenced in various databases of the NCS, where they are used along with the supplier’s part number to form a reference which is held on the National Stock Number (NSN) record. This reference enables users of the NCS to determine who supplies any given part and provide for traceability.

CAGE codes are all five characters in length

There is no meaning encoded in the code itself, other than the underlying NCB; it is simply a unique identifier.

  • In the United States – The first and last characters must be numerals; the remaining characters can be numerals or any letter except for I or O. Example: 81349
  • In France – The first character is the letter F or M and the last character must be a numeral. Example: F1234
  • In the United Kingdom – The first character is either the letter U or K and the last character must be a numeral. Example: K1F21
  • In Spain  The last character is the letter B and the first character must be a numeral. Example: 001ZB
