When you have received your certificate with your company prefix you can start to calculate the numbers themselves. You use our page “calculate check digit” to calculate your SSCC.
The certificate shows what the unique structure for your SSCC looks like.
The structure consists of a combination of digits and letters. For a series of 10,000,000 numbers, for example, the structure looks like this:
N 123456789 AAAAAAA K
N – is a leading digit that can be from 0 to 9
123456789 – is your company prefix which must be part of all SSCCs you create.
AAAAAAA – is a sequence number. You decide this yourself. It can be anything from 0000000 to 9999999. We recommend that you number sequentially, i.e. 0000001, 0000002, 0000003 and so on. It is important that you keep track of the sequence numbers you have used since this is not something we register.
K – is a check digit that you calculate on our website. You cannot choose the check digit, it must be calculated. You can also calculate the check digit when you are logged in to MyGS1. Note that you must calculate the new check digit for every new SSCC you create.
The SSCC is then printed on a data carrier such as GS1-128.
