  SECTION II — GEOGRAPHICAL ENTITY CODES
  2-2. On 19 February 2004, NATO Standardization Agreement (STANAG) 1059 (Edition 8), Letter Codes
  for Geographical Entities, was promulgated. The aim of this agreement is to provide unique three letter codes
  for use within NATO to distinguish geographical entities. However, due to implementation difficulties, a 28
  January 2005 memorandum from the NATO Standardization Agency declared that until STANAG 1059
  could be fully implemented, the two letter code would be used for the technical automated information system
  domain, while in all other (nontechnical) administrative areas, the three letter code would be used. The list
  on pages 106 through 111 provides both the two letter and three letter codes.
