How to format each number
What do I need to start using the system?
1. EAN·UCC company prefix
2. Item reference
3. Check digit
1. Get a company prefix
You need to get an EAN·UCC company prefix, by contacting
GS1 JORDAN . In general the EAN·UCC company
prefix comprises 6 to 10 digits depending on the need of the company.
The EAN·UCC company prefix, unique worldwide,
is the first part of the number used
to uniquely identify a product or service.
Example:
|
EAN·UCC company prefix
|
|
6 |
2 |
5 |
1 |
2 |
3 |
4 |
5 |
6 |
2. Item reference
You will be assigned a block of numbers that your organisation will use as an item
reference.
The item reference has typically 1 to 6 digits, it is a non-significant number,
which means that the individual digits in the number do not relate to any classification
or convey any specific information.
The simplest way to allocate item references is sequentially, that is 000, 001,002,
003, etc.
Example:
|
EAN·UCC company prefix
|
Item references
|
|
6 |
2 |
5 |
1 |
2 |
3 |
4 |
5 |
6 |

1 |
3. Calculate the Check digit
The check digit is the last digit (rightmost) of the GTIN (Global Trade Item Number).
It is calculated from all other digits in the number and is used to ensure that
the bar code has been correctly scanned or that the number is correctly composed.
Example:
|
EAN·UCC company prefix
|
Item references
|
Check digit
|
|
6 |
2 |
5 |
1 |
2 |
3 |
4 |
5 |
6 |
0 |

1 |
1 |
Warning!
The number must always be used as a whole.
No processing of data should be based on any part of a GTIN.
