Northern Ireland (UK) TIN and VAT Information

EU VAT number

The Northern Ireland VAT number for EU-trade is a 9-digit number prefixed by the ISO 3166-1 alpha-2 temporary country code XI. After Brexit the UK has left the EU VAT area, but Northern Ireland remains part of the EU VAT area for trade in goods. The number follows the same rules as the UK VAT number, and is the only UK VAT number that is still verifiable by the EU VIES system.
