You can check GTIN
Preferences
by following the below path. Go to
Company > My Company >Unique ID Generators >GTIN
Preferences
tab. The GTIN
Preferences
tab displays issuing agency, company prefix, and GTIN length. The issuing
agency field is not editable. Your administrator can store GS1 as the preferred
issuing agency. GTIN length can be 14,13, 12, and 8.
The DI (Device Identification)
number is filled automatically based on the GTIN number count.
GTIN consists of four parts: indicator, company prefix, item reference
number, and check digit.
- Indicator- It is a single digit from 0 to 9 that indicates the level.
- Company prefix- GS1 company prefix is administrated by GS1. It can be
7 to 10 digits in length.
- Item reference number- You can assign an item reference number to a
product. The length of the item reference number depends on the length of the
GS1 Company Prefix.
- Check digit- The check digit calculation is as follows: Eg: GTIN is
036000241453.
- Add the odd number digits: 0+6+0+2+1+5 = 14
- Multiply the result by 3: 14 × 3 = 42
- Add the even number digits: 3+0+0+4+4+3 = 14
- Add the two results together: 42 + 14 = 56
- To calculate the check digit, take the remainder of (56 / 10),
which is also known as (56 modulo 10), and subtract from 10. So, the check
digit value is 4.
