IS-R-006

Layer peppol·Checked against Peppol BIS Billing 3.0 2026.5

What does IS-R-006 mean? If seller is icelandic and payment means code is 9 then a 12 digit account id must exist — Ef seljandi er íslenskur og greiðslumáti (BT-81) er krafa (kóti 9) þá skal koma fram 12 stafa númer (bankanúmer, höfuðbók 66 og reikningsnúmer) (BT-84)

Why did my invoice fail IS-R-006?

If the seller is Icelandic and the payment means code (BT-81) is 9 (claim/krafa), a 12-digit account identifier (BT-84) must be present, consisting of the bank number, ledger 66, and account number. This Peppol BIS 3.0 Icelandic country rule ensures the Icelandic claim payment can be routed; in UBL BT-84 is cac:PaymentMeans/cac:PayeeFinancialAccount/cbc:ID.

Official rule text

If seller is icelandic and payment means code is 9 then a 12 digit account id must exist — Ef seljandi er íslenskur og greiðslumáti (BT-81) er krafa (kóti 9) þá skal koma fram 12 stafa númer (bankanúmer, höfuðbók 66 og reikningsnúmer) (BT-84)

Common causes

PayeeFinancialAccount/ID missing when PaymentMeansCode is 9
Account identifier shorter or longer than 12 digits
Account identifier contains separators (dashes, spaces) instead of 12 plain digits

How do I fix it?

<cac:PaymentMeans>
  <cbc:PaymentMeansCode>9</cbc:PaymentMeansCode>
  <cac:PayeeFinancialAccount>
    <cbc:ID>013266001234</cbc:ID>
  </cac:PayeeFinancialAccount>
</cac:PaymentMeans>
