ID. needed. What are they?

[Mike Cecil]

The NATO stock number country code is correctly described as the code which identifies the country assigning the NATO item identification code or NAMSA management control number. The numbers in Code sequence as at October 1996 were (and still are):

00 United States
01 United States
09 NAMSA (used only for NAMSA Management Control Numbers)
11 NATO
12 Germany
13 Belgium
14 France
15 Italy
17 Netherlands
20 Canada
22 Denmark
23 Greece
24 Iceland
25 Norway
26 Portugal
27 Turkey
28 Luxembourg
33 Spain
99 United Kingdom

In simple terms, it is the country code assigned to an object that identifies the country of origin/manufacture.

Australia's Defence Stock Number (DSN) code is 66, formerly referred to as the NSN (NATO Stock Number). Australia is not a formal member of NATO.

As more countries have been admitted to NATO since then, the list has probably expanded by a few more code numbers.
