What is a GLN number used for?
The abbreviation GLN stands for Global Location Number.
- A GLN is used to identify companies and parts of companies – such as warehouse locations or branches – worldwide, making them clearly identifiable.
- The GLN is a prerequisite for electronic data interchange (EDI). Every EDI participant must therefore have a GLN code and use it to identify themselves. The GLN code is sent with the structured information of the EDI message. Each EDI partner has its own identifier.
- The GLN is also the prerequisite for generating GTIN or SSCC numbers.
What does a GLN consist of?
A GLN consists of 13 digits:
- GS1 base number (GS1 prefix or country code)
- Location reference
- Check digit
