unsupported_register

No register is held for that identifier type or country

The identifier type is recognised but this server holds no register that could answer it.

Free. An identifier no register could answer for never costs a credit.

What it means

Company numbers are only unique inside their own register, so a country is required and only the registers installed here can answer. GB is the country covered today.

This is a limit of the data on this server, never a statement about the company.

What to do

Use a LEI if the entity has one: those are global and need no country.

Example response

{
    "identifier": "12345678",
    "identifier_type": "company_number",
    "found": false,
    "reason": "unsupported_register"
}

Abbreviated: a real answer carries all 33 fields, listed in the validate-phone reference.
