Belgian Company Lookup → JSON

How the lookup works

Type or paste one Belgian enterprise number or VAT number in any common form: 0417.497.106, BE0417497106 or the old 9-digit 417497106. The number is first validated in your browser with the modulo-97 rule, so a typo is caught before anything goes online. Only a valid number is sent to our server, which asks two public registers at the same time:

• VIES, the European Commission's VAT validation service, which queries the Belgian VAT administration and returns whether the VAT number is active, plus the registered name and address.
• The Peppol network: an SML lookup tells whether the company is registered as 0208: + enterprise number, and the SMP of its access point lists which document types (invoice, credit note, order...) it can receive.

Everything else in the record (the formatted enterprise number, VAT number and both Peppol IDs) is computed locally from the digits.

Sample output

Input 417497106 gives a record shaped like this (name and address shortened):

{
  "enterpriseNumber": "0417.497.106",
  "enterpriseNumberDigits": "0417497106",
  "vatNumber": "BE0417497106",
  "peppolIds": {
    "primary": "iso6523-actorid-upis::0208:0417497106",
    "vat": "iso6523-actorid-upis::9925:BE0417497106"
  },
  "vies": { "valid": true, "name": "...", "address": "...", "checkedAt": "..." },
  "peppol": { "registered": true, "smp": "...", "documentTypes": [ ... ] }
}

Copy it or download it as company-0417497106.json to feed a spreadsheet, a CRM import or a supplier-onboarding checklist.

Edge cases worth knowing

• Valid but not active for VAT. Many non-profits, some VAT-exempt businesses and stopped companies have an enterprise number but no active VAT number. VIES then answers "not valid" even though the number is correct.
• Not on Peppol under 0208. Some companies registered only under the VAT-based scheme 9925. Check both IDs with the Peppol ID checker before concluding they cannot receive e-invoices.
• Establishment units (numbers starting with 2 to 8) are not companies and are not in VIES.
• VIES downtime. The Belgian VIES node is sometimes unavailable for minutes; the record then carries an error instead of a name, and you can retry.

Legal form, NACE activities, directors and establishment units live in the KBO/BCE, which has no free real-time API. Decode the codes from the monthly KBO Open Data files with the KBO code lookup and NACE-BEL lookup, and read the guide to Belgian company identifiers for how the numbers relate.
