Fatal — invoice rejected Party & address Shared Peppol rule PINT-AE 2026.5

How to fix ibr-068 in UAE e-invoicing

What is ibr-068?

ibr-068 is a fatal validation rule in the UAE's Peppol PINT-AE e-invoicing specification, inherited from the shared Peppol layer. It is checked against the invoice document and belongs to the Party & address rule group. An e-invoice that fails ibr-068 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

GLN MUST have a valid format according to GS1 rules for endpoints (ibt-034), (ibt-049), party identification (ibt-029), (ibt-046), (ibt-060), legal entities (ibt-030), (ibt-047), (ibt-061).
UAE impact: this is a fatal rule from the shared Peppol layer, enforced in the UAE profile — an invoice failing it is rejected at the Accredited Service Provider gateway before it ever reaches the FTA. A rejected invoice means resubmission delays, and late transmission risks the AED 100-per-invoice penalty under Cabinet Decision No. 106 of 2025.

Where it applies

This rule is checked against the invoice document of your UBL 2.1 invoice: 

cbc:EndpointID[@schemeID = '0088'] | cac:PartyIdentification/cbc:ID[@schemeID = '0088'] | cbc:CompanyID[@schemeID = '0088']
