Cyprus VAT number format

A Cyprus VAT identification number is the prefix CY followed by 8 digits + 1 letter; CY10259033P 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 CY, then 8 digits + 1 letter. The regular expression the API applies to the part after the prefix is ^[0-9]{8}[A-Z]$; letters are upper-cased and spaces, dots and dashes removed before the test.

The check digit

Cyprus 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 Cyprus VAT number; only VIES says whether it is registered. The free check below asks VIES live and shows the registered name and address where Cyprus 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.
