PEPPOL-COMMON-R044

Explanation

A number on the invoice – a party's electronic address, identifier or registration number – is marked as an IPA code (Codice Univoco Unità Organizzativa). This code identifies an office of the Italian public administration and consists of exactly 6 letters or digits, without spaces or special characters.

How to fix

Ask the seller for a corrected invoice that states the correct six-character IPA code given by the public body. If it is the buyer's number, give the seller the correct one.
