IS-R-001

What does IS-R-001 mean? If seller is icelandic then invoice type should be 380 or 381 — Ef seljandi er íslenskur þá ætti gerð reiknings (BT-3) að vera sölureikningur (380) eða kreditreikningur (381).

Why did my invoice fail IS-R-001?

If the seller is Icelandic, the invoice type code (BT-3) should be 380 (commercial invoice) or 381 (credit note). This Peppol BIS 3.0 Icelandic country rule restricts the wider UNCL1001 code list to the two document types accepted in Iceland; in UBL the value is carried in cbc:InvoiceTypeCode (or cbc:CreditNoteTypeCode).

Official rule text

If seller is icelandic then invoice type should be 380 or 381 — Ef seljandi er íslenskur þá ætti gerð reiknings (BT-3) að vera sölureikningur (380) eða kreditreikningur (381).

Common causes

• Using another UNCL1001 code such as 386 (prepayment) or 384 (corrected invoice)
• ERP default document type code not adjusted for Icelandic sellers

How do I fix it?
