DOD UID Part Mark – What data can I use?
What's in My UID?
There are several numbering schemes that the government will allow you to use as UID data, such as VINs (vehicle identification numbers) and Aircraft Tail Numbers.
For the majority of us, we have a choice between "Type 1" and "Type 2" UIDs.
Both Type 1 and Type 2 UIDs start with an enterprise identifier (nearly always your CAGE code).
Type 1 UIDs then have a sequential counter (first UID is CAGE followed by "1", second UID is CAGE followed by "2", etc.).
CAGE + Sequential Counter
1HLD9 + 00001
1HLD9 + 00002
1HLD9 + 00003
Type 2 UIDs instead use a part number and the part's serial number.
CAGE + Part + Serial Number
1HLD9 + AGF0014 + 67GG14
1HLD9 + YTT07AA + 67GG23
1HLD9 + AGF0014 + 67GH30
If you use Type 1 UIDs you have a greater need for a "UID Data Management System" which keeps track of which UID goes with which part and serial number. These systems cost tens of thousands of dollars to start, require on-site system installers and trainers, and have hefty annual fees.
Type 2 UIDs are pretty simple because they use part numbers, which you already manage, and serial numbers, which you also probably already manage.
Our advise is for most suppliers to use Type 2 unless you find some deal-breaker that forces you to go with Type 1.
