Address verification step

Address verification includes `AddressForm` and `AddressDocument` steps.

Address Documents

Flow description

1. The user uploads one of the listed documents.

2. The system analyzes the provided document with a specific Azure's Document Recognition model (model types), which is selected depending on the document type (document analyzer types).

3. The system extracts the following key data points:

   • Address;

   • Document issue date;

   • Document owner's full name.

   In case the address cannot be extracted - the appropriate error (InvalidDocuments) is raised.

4. The system checks if the document is not older then 3 months and validates the address (as described in AddressForm section, point 2).

5. Document expiry check, address validation result, and the full name extracted from the document are saved for further checks (covered in AddressForm section, point 4).

Address Form

Flow Description

1. User provides the following data via preset form:

   • First Name;

   • Last Name;;

   • Country (This field is filled by the user's selection in the previous step - AddressDocuments);

   • City;

   • Street;

   • Building Number;

   • Zip Code.

2. The system serializes the received data and sends it to Azure's azure.mgmt.billing.BillingManagementClient.address.validate() API (source). Azure API checks if the provided address actually exists. Up to 3 additional address suggestions may be processed, and only in case they are not different from the initially provided address.

3. Validation result (bool) and applicant's full name are saved and stored for further comparison with these received from the previous step (AddressDocuments).

4. If Auto Approve is enabled for this verification step, the system makes the following checks:

   • Both addresses, received from AddressForm and AddressDocuments, are valid (validated as described in point 2);

   • Full name, extracted from the document, matches the one provided via the form;

   • The document, provided in AddressDocuments step, is not older then 3 months.

   If all of these conditions are met, this specific verification is automatically approved.
