Fin.com verifies every natural person through two document categories: an identifying document that proves who they are, and an address document that proves where they live. This applies both to an individual customer and to each associated party (owner, director, or controlling person) of a business customer.
Files must be uploaded first through the Upload document endpoint. The endpoint returns a URI that you then reference in the files array of the attach request.

Where documents are submitted

​
Identifying documents

Accepted government-issued identity documents, and the number of images each one needs: Requirements that apply to every identifying document:
  • The document must not be expired. expiry_date must be a future date.
  • number, country, and expiry_date are required for all types except SELFIE.
  • state is required when type is DRIVERS_LICENSE and country is USA. It is optional for a license issued elsewhere and is not accepted for other document types.
  • Images must be clear, uncropped, and show the full document including any machine-readable zone.
If you plan to issue USD SWIFT virtual accounts for your customers, upload an identifying document that matches the recommended type for the country that issued it. Other accepted types may still pass verification, but they can prevent a USD SWIFT virtual account from being issued.

​
Address documents

Address documents must be dated within the last 90 days and must show the person’s full name and residential address.
For an individual customer, exactly one address document is required and its country must match the customer’s country_of_residence.
Tax identification numbers are captured separately from these documents. See Individual Tax ID documents for the accepted type per country.
