EU VAT guide
Greece EL VAT number
Greek VAT numbers are checked in VIES with the EL country code, not GR.
EL vs GR
Greece is commonly represented by GR in many country-code contexts, but VIES uses EL for Greek VAT validation.
If you paste a Greek VAT ID, make sure the selected checker country is EL.
Format mistakes
Remove spaces and punctuation before checking the number, and avoid entering the country prefix twice.
A correctly formatted Greek VAT number still needs a live VIES response before it can be treated as validated.
