Where to Find Your Tax Identification Number for AdultWork

If AdultWork asks for a Tax Identification Number (TIN), use the identifier required for the person or legal entity receiving the funds. Individual and company identifiers can differ within the same country.

Check an authoritative source

Start with your tax account, assessment notice, registration documents, or the relevant national tax authority. AdultWork also links to international jurisdiction information through its tax guidance.

Do not guess from a generic length rule or enter a company registration number merely because it is the only number you have. The correct identifier depends on the country and the form's purpose.

Submit it securely

Verify the request through AdultWork's official account or support process and use the designated form. If your situation does not fit the available field, ask support which information it needs before submitting an invented or incomplete number.
