What format is a Cyprus TIC?

A Cypriot Tax Identification Code (TIC), also written ΑΦΤ, is 8 digits followed by one uppercase Latin letter — 9 characters in total. The trailing letter is a check character computed from the 8 digits, and the same number serves as the Cyprus VAT identifier in VIES.

How is the check letter calculated?

Digits in odd positions (1st, 3rd, 5th, 7th) are translated through a fixed table (0 maps to 1, 1 maps to 0, 2 maps to 5, and so on up to 9 maps to 21); digits in even positions use their plain value. The eight values are summed, taken modulo 26, and that index 0-25 maps to a letter A-Z.

Why do some Cyprus TICs start with 0, 1 or 6?

The leading digits indicate the taxpayer category. Legal entities historically begin with 1, while individual TICs issued since March 2023 begin with 6. The validator checks the math of the trailing letter rather than enforcing a particular leading digit.

Does a valid check letter mean the taxpayer is registered?

No. A valid check letter only confirms the TIC is internally consistent. It does not confirm the taxpayer is registered with the Cyprus Tax Department or active in the EU VIES system — use the official register to verify that.

Is my data sent anywhere?

No. The check-letter calculation runs entirely in your browser. The TIC you enter never leaves your device and no external lookup is performed.

Cyprus TIC Validator

A Cyprus Tax Identification Code (TIC) — written ΑΦΤ in Greek — is the identifier the Cyprus Tax Department issues to individuals and companies, and it doubles as the country’s VAT number for intra-EU trade. It is 8 digits followed by a single check letter, and that letter is derived from the digits via a modulo-26 algorithm. This free tool runs the exact check in your browser, which is what you need for VIES registration and company-law filings.

How it works

The trailing letter is a check character computed from the 8 digits:

Uppercase the input and strip separators, leaving 8 digits and one letter.
For digits in odd positions (1st, 3rd, 5th, 7th), translate them through a fixed table: 0->1, 1->0, 2->5, 3->7, 4->9, 5->13, 6->15, 7->17, 8->19, 9->21.
For digits in even positions (2nd, 4th, 6th, 8th), use their plain value.
Sum all eight values and take the result modulo 26.
That index 0-25 maps to a letter A-Z, which must equal the 9th character.

Example and notes

Take 10259033P. The odd-position digits 1, 2, 9, 3 translate to 0, 5, 21, 7 and the even-position digits 0, 5, 0, 3 stay as-is. The total is 41, and 41 mod 26 = 15, which maps to the 16th letter P — matching the supplied check letter, so the TIC is valid.

A passing check letter confirms internal consistency only. It does not confirm the taxpayer is registered or active in VIES — only the Cyprus Tax Department’s register can do that. Everything here runs locally, so the TIC never leaves your device.
