How to Check a Cyprus VAT Number

Why you must verify Cyprus VAT numbers

Before issuing a zero-rated B2B invoice to a Cyprus or EU business you must verify their VAT number on the EU VIES system. If the number is invalid the supply defaults to B2C — meaning you should have charged VAT. If you did not charge VAT and the number is invalid the VAT liability falls on you as the supplier, not on your customer. You cannot retrospectively recover the VAT from a customer who paid a net price. The verification takes 30 seconds and the risk of not doing it can cost thousands.

How to verify a Cyprus VAT number on VIES

1. Go to ec.europa.eu/taxation_customs/vies
2. Select Cyprus from the member state dropdown
3. Enter the VAT number without the CY prefix — just the 9-digit number
4. Click Verify
5. VIES returns: Valid (currently registered) or Invalid (not registered or cancelled)
6. Save a screenshot or record of the result including the date — this is your audit evidence

What to do if a Cyprus VAT number is invalid

If VIES returns an invalid result for a customer's VAT number do not issue a zero-rated invoice. Contact your customer and ask them to provide their correct VAT number or to confirm their VAT registration status. If they cannot provide a valid VAT number the supply is B2C and Cyprus VAT applies at the appropriate rate. If you have already issued a zero-rated invoice and the number is invalid you need to issue a corrected invoice adding the VAT and either charge the customer the additional amount or absorb it as a cost.

VIES validation for non-Cyprus EU numbers

VIES validates VAT numbers from all 27 EU member states — not just Cyprus. When a French, German or Polish business gives you their VAT number use VIES to check it the same way — select their country from the dropdown and enter their number without the country prefix. All EU VAT numbers follow the same verification process through the same VIES portal.
