The company number is the legal registration number of an entity provided by the relevant national authority in the country where it is registered. The company number is one of the elements checked during the user verification process. The number is required for Business-type legal users, and recommended for Soletraders and Organizations if it exists. See the verification requirements for details. The CompanyNumber must be in the correct format for their country of registration, as determined by the Country of the HeadquartersAddress. For Business-type users, an incorrect format blocks the verification process.

​
Validating format prior to verification

Platforms should validate the format of the CompanyNumber for businesses before requesting verification. You can set up hook notifications for the following event types to be notified when a user’s number corresponds or not to the expected format:
  • LEGAL_COMPANY_NUMBER_VALIDATION_SUCCEEDED
  • LEGAL_COMPANY_NUMBER_VALIDATION_FAILED
These hooks can be triggered on the following calls: You can also use the following endpoint to check the format of the number and retrieve the validation rules applied for a given country:

Accepted format by country

The countries in the table below have rules in place regarding a valid format for their country number. Countries not in the list have no formatting rules in place – the number format should match the verification documents. The regular expressions for the accepted formats are returned on the POST Validate the format of User data endpoint.
Note - Only alphanumeric characters assessedThe company number formatting rules only evaluate letters and digits. Any other characters, like dashes or spaces, in the CompanyNumber string are removed beforehand.In some cases, a punctuation mark (such as a hyphen or dash) is given in the table below for information purposes only because it is commonly used locally.
