Which number goes where

VAT number: Fifteen digits starting and ending with 3. The seller needs it on every invoice, and a registered buyer on a tax invoice. A wrong format rejects the invoice (BR-KSA-40 for the seller, BR-KSA-44 for the buyer).
CR, unified number, national ID and Iqama: They identify a buyer not registered for VAT, in the buyer identifier field with their type, not in the VAT number field (BR-KSA-14). Letters and digits only.
National ID and Iqama: A number with the right shape but a wrong check digit comes back with warning BR-KSA-F-13 on an invoice already issued.

The most common mix-up: a CR or unified number in the VAT number field. The first has ten digits; a VAT number has fifteen.

Frequently asked questions

Fifteen digits, the first and the last a 3, in Latin digits, with no spaces or dashes. Any other shape is rejected before the rest of the invoice is read.

With another identifier and its type: the CR, the unified 700 number for government bodies, or the national ID or Iqama for individuals. It goes in the buyer identifier field, not in the VAT number field.

Because ZATCA verifies it. A national ID with the right shape but a last digit that fails the check comes back with warning BR-KSA-F-13 on an invoice already issued, so it is better caught before issuing.

No. It checks the format only and sends the number nowhere. To confirm a VAT number is registered and see the business name, use the VAT number lookup.
