Ireland VAT number check (Irish IE VAT ID)
Use this Ireland VAT number check to verify an Irish VAT ID in VIES. Use IE for Ireland; Northern Ireland uses XI for the relevant goods transactions. Read the current result and keep a dated copy for your records.
Ireland VAT number format: IE, XI or GB?
Use the prefix on the business's VAT number to choose the right check. IE and XI identify different VAT registrations.
- IE — Ireland: use the Irish VAT ID in the checker below. IE1234567AB is an invented format example, not a verified business.
- XI — Northern Ireland: for the goods transactions covered by HMRC's guidance, use the XI number and the Northern Ireland XI VAT check.
- GB — United Kingdom: follow the UK VAT number check guide for the HMRC route. Do not replace GB with IE or XI to make a number pass.
If you only have the business name, ask it for its full VAT ID rather than guessing its prefix.

How to check an Irish VAT number in VIES
An Irish VAT number check needs the VAT ID, not just the business name.
- Select Ireland or paste the complete number with the IE prefix.
- Run the check to ask VIES for the current intra-EU validation response.
- Compare any returned business details and save the dated result for your records.
If VIES returns invalid for an Irish VAT number
First confirm the IE number with the business. An invalid response can mean that the number does not exist, is not activated for intra-EU transactions, or its registration is not yet finalised. If the business says it is registered, ask it to confirm its status with Irish Revenue. A registry error or timeout leaves the check unresolved; it is not an invalid result.
Expected format
A typical Ireland VAT ID looks like IE1234567AB. You can paste the full number with the IE prefix or select Ireland in the checker.
Ireland VAT check questions
How do I check an Irish VAT number in VIES?
Select Ireland or paste the full VAT ID with its IE prefix, then run the checker. VAT Validate checks the local format before contacting VIES and shows whether the response is valid, invalid, or unavailable.
What format does an Irish VAT number use?
Irish VAT numbers use the IE prefix followed by an eight- or nine-character local identifier, for example IE1234567AB. Use the IE prefix once, then keep the dated VIES result with the invoice record.
Is an Ireland IE VAT number the same as a Northern Ireland XI number?
No. Ireland uses IE. Northern Ireland uses XI for the goods transactions covered by HMRC guidance. Use the VAT ID supplied by the business; do not change its prefix to obtain a valid response.
Can I find an Irish VAT number by company name?
This checker needs the VAT number; it does not search by company name. Ask the business for its VAT ID, check it in VIES, then compare any returned details with your records.
What should I do if an Irish VAT number is unavailable in VIES?
Retry later and review the VIES error status before treating the number as invalid. A temporary Irish or EU registry outage is not proof that the VAT number is invalid.
If the registry does not answer, review the VIES error guide. For a usable response, run the checker below and keep the dated result with the invoice record.
For registration or tax-account questions, consult the Irish Revenue VAT guidance.
What VIES can return
- Valid: the VAT number is currently confirmed for intra-EU transactions.
- Invalid: VIES did not confirm the number as valid at the time of the check.
- Unavailable: VIES or the national VAT registry did not reply.
Before relying on the result
Match the VAT result with your customer's invoice details and keep your own evidence of the check. A valid VIES response is a useful record, but it is not a substitute for your compliance workflow or advice from a tax professional.
If Ireland is unavailable in VIES, retry later before treating the VAT number as invalid. Member-state registry outages can look like a failed check even when the number itself is fine.
