GS1 Company Prefix

[Gary Thompson <gthompson@xxxxxxxxxxx>]

I am in early testing of an EDI 856 Advance Ship Notice app.

One detail concerning me is the "Company Prefix" that part of
the SSCC-18 Serial Shipping Container Code.

I did ask for a GS1 Company number, but my company has
balked at paying.

At this time I am using our 9 digit company DUNS number
as the Company Prefix.

I have been able to gen 20 digit numbers with a check digit
that passes a Check Digit Calculator available on the web.

Does anyone have current, real-world experience using a
DUNS number to form an SSCC-18 ?

Thanks!

P.S.
I am using the following "structure" for the SSCC-18:

AAeCCCCCCCsssssssssD

Where:        AA  Application Identifier (AI)

                  ("00" is the AI value for SSCC-18 data structure)

               e  Extension digit (has no defined use and is
                     used as an extra digit for the Company
                     Prefix and Serial Number combination).

         CCCCCCC  Company Prefix of 7-10 digits.  (9 for my app)

       sssssssss  Serial Reference of 6-9 digits. (7 for my app)

                  The total length of the Company Prefix and
                     Serial Reference is 16.
                     (17 if the Extension Digit is used ??)

               D  Modulo 10 Check Digit.
