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