Estonia: company identifier formats (Registry code)

Shape, check digit, accepted and refused examples and the API call for Registry code in Estonia. Every example on this page is run through the same validators as the free identifier validator, so a value shown as accepted is a value the validator accepts.

Notes and scope

The VAT number (KMKR) is a separate number and cannot be derived from it. Sole traders (FIE) are never served.

Call it from code

curl "https://api.prometiam.com/functions/v1/risk-api/companies/search?country=EE&company_number=10060701" \
  -H "Authorization: Bearer YOUR_API_KEY"

Shape notation: N digit · L letter · X digit or letter · C check digit or character · {n} repeat n times.

A valid shape and check digit prove that a number is well-formed, not that a company holds it. Only a lookup in the register answers that.
