§ HOW IT WORKS

Three seconds. One source of truth.

  2. 02We check HMRC directly. Not a cached database — a live call to the HMRC Check UK VAT Number API. Same data a tax inspector sees.
  3. 03You get The Stamp. Company name, address, status, timestamp, and a Countersure verification ID. Pro accounts can export an audit-ready PDF.
