1. THE NATO CODIFICATION SYSTEM:

1.7. CODIFICATION SERVICES AND EXCHANGE OF CODIFICATION DATA

In order to obtain the maximum benefit from the NATO Codification System, internationally agreed methods, formats and procedures have been set up to facilitate the regular exchange of codification data and services among member nations.

Standard procedures for exchange of data by telecommunication means have been established and special input and output codes and formats have been agreed upon.

The NATO and Sponsored nations also exchange general data, including national NCAGE Data, which details the full names, addresses, telephone, fax, e-mail and industrial classification codes of all recorded national manufacturers and suppliers. The nations also supply the NSN Cross Reference Lists (CRLs), which contain nationally assigned NSNs cross-referenced to manufacturer's Refsets (Reference Sets), which are the identifying data string created by joining the manufacturer's NCAGE and reference/drawing numbers together, to NSPA in order to produce the NMCRL.

Some NATO nations are currently able to exchange Materiel Management Data (MMD) and other nations are planning to introduce this facility. MMD includes information necessary to acquire, account for and generally manage Items of Supply, such as price, source of supply, shelf life. The exchange of these data elements is accomplished on the basis of STANAG 4199 (Uniform System of Exchange of Materiel Management Data).
