Greece VAT number format

A Greece VAT identification number is the prefix EL followed by 9 digits (prefix EL, not GR); EL094259216 is a well-formed example. The national check digit is public, so a mistyped number is caught before VIES is asked. Structure as published in the Commission’s VIES FAQ, consulted 2026-10-24.

Structure

Prefix EL, then 9 digits (prefix EL, not GR). The regular expression the API applies to the part after the prefix is ^[0-9]{9}$; letters are upper-cased and spaces, dots and dashes removed before the test.

The check digit

Greece publishes the algorithm of its check digit, so an impossible number is refused before VIES is asked: the answer says structure.checksum: "failed", costs nothing and reaches no upstream. The same algorithms are implemented by the open libraries (jsvat, python-stdnum).

How to validate it

The structure says whether a string can be a Greece VAT number; only VIES says whether it is registered. The free check below asks VIES live and shows the registered name and address where Greece publishes them; the API does the same from your code.

What a valid answer proves

That the number was registered for intra-EU trade at the moment of the check. Keep the date and, on paid tiers, the VIES consultation number: together they are the evidence a tax audit asks for when an intra-EU supply was zero-rated.

Questions

9 digits (prefix EL, not GR), after the two-letter prefix EL: EL094259216 is an example.
Is EL094259216 a real VAT number?
It is a well-formed example used in the documentation; whether it is registered today is VIES’s answer, not this page’s. Check it with the free tool.
Why EL and not GR?
VIES uses EL for Greece (the ISO code is GR); a number sent with the GR prefix is normalised to EL by the API.
