How many digits is an HVHH?

An HVHH is exactly 8 digits. It is a sequential identifier with no embedded date or region, assigned when a taxpayer registers with the State Revenue Committee.

Does this tool verify a check digit?

No. The State Revenue Committee does not publish a check-digit algorithm for the HVHH, so this tool validates the documented structure — exactly 8 numeric digits. A passing format check rules out the most common length and character errors.

Is the HVHH the same as a VAT number?

Yes. Armenia uses the HVHH as the single taxpayer identifier for VAT-registered businesses; there is no separate VAT number. The same 8-digit code appears on VAT invoices and the e-Invoicing.am system.

Is my HVHH sent to a server?

No. Validation runs entirely in JavaScript inside your browser. Nothing is uploaded, logged, or stored, and the tool works offline once loaded.

Q: What is an HVHH?

HVHH (ՀՎՀՀ — Հարկ վճարողի հաշվառման համար) is the taxpayer identification number assigned by Armenia's State Revenue Committee (SRC). Every registered company and individual entrepreneur receives one, and it is used for VAT, e-invoicing on e-Invoicing.am, and customs declarations.

Armenian HVHH at a glance

The HVHH (ՀՎՀՀ — Հարկ վճարողի հաշվառման համար, “taxpayer registration number”) is Armenia’s taxpayer identification number, issued by the State Revenue Committee (SRC). Every registered company and individual entrepreneur receives an 8-digit HVHH, which is used for VAT, the e-Invoicing.am system, and customs declarations. It is the single tax identifier — there is no separate VAT number.

How it works

The State Revenue Committee does not publish a check-digit algorithm, so validation is a structural format check against the documented rule:

HVHH = exactly 8 numeric digits
  - strip spaces and hyphens
  - reject any non-digit character
  - reject anything other than 8 digits

The HVHH is a sequential code with no embedded date, gender, or region, so there is no additional structure to verify offline. The tool normalises separators, confirms every character is a digit, and checks the length.

Tips and notes

A valid 8-digit format confirms the HVHH is well-formed and free of common transcription errors, but it does not prove the taxpayer is registered or VAT-active — confirm that through the State Revenue Committee’s public lookup. When importing Armenian supplier data, always strip separators and store the clean 8-digit form so the same HVHH compares equal regardless of how it was formatted on the source document.
