GLN (Global Location Number)

Σύντομη απάντηση

13-digit GS1 code uniquely identifying a location (HQ, warehouse, store, delivery dock).

Βασικά συμπεράσματα

  • NAD+BY (Buyer) → buyer GLN
  • NAD+SU (Supplier) → supplier GLN
  • NAD+DP (Delivery Place) → delivery location GLN (usually the retailer store/DC, NOT the legal seat)
  • NAD+IV (Invoicee) → invoicing entity GLN

Definition

GLN (Global Location Number) is a 13-digit GS1 identifier marking a unique physical or legal entity in a commercial transaction: legal seat, warehouse, store, retailer delivery dock, specific receiving bay.

How it appears in EDI

  • NAD+BY (Buyer) → buyer GLN
  • NAD+SU (Supplier) → supplier GLN
  • NAD+DP (Delivery Place) → delivery location GLN (usually the retailer store/DC, NOT the legal seat)
  • NAD+IV (Invoicee) → invoicing entity GLN

Common confusion: physically shipping to the legal-seat GLN instead of the store GLN → rejected order and penalty.

Practical example: Carrefour

Carrefour has one GLN for the legal entity (invoicing) and separate GLNs for each hypermarket / distribution center. The supplier must keep a complete map: internal location code ↔ Carrefour GLN.

How to obtain one

  • Companies with a GS1 prefix issue their own GLNs
  • For retailer/partner GLNs, they are shared at onboarding or pulled from GDSN
  • CRMconnect keeps a pre-mapped library for native retailers (Carrefour, Auchan, Kaufland, Lidl, Mega Image, Profi, Metro, Dedeman, Hornbach, Leroy Merlin)

Ενημέρωση:

Συχνές ερωτήσεις

Can a GLN be reused if a location closes?+

No. GS1 rules require a deactivated GLN not to be reused for at least 48 months from deactivation.

Difference between GLN and GTIN?+

GTIN identifies a product (what); GLN identifies a location or legal entity (where/who).
