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

How to fix ibr-sr-55 in UAE e-invoicing

What is ibr-sr-55?

ibr-sr-55 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 a postal address and belongs to the Party & address rule group. An e-invoice that fails ibr-sr-55 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

The Tax Representative Postal Address Line (ibt-164) MUST occur maximum once
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.
