Supplementary documents

AI Tools

Yoti offers the ability to request additional documents to enhance the verification of the user. You can request this on its own as part of a new session or include in your current session.

Please see our document comparison feature to complement the supplementary documents.

Good to know

Yoti will only compare the NAME of the users between the documents uploaded.

Yoti supports the ability to upload the following documents:

Document type	Validity
Utility bill	From the past three months.
Council tax bill	From the past 12 months.
Phone bill	From the past three months.
Bank statement	From the past three months.

Text Extraction

A request to obtain the data printed visually on a document, in structured form. If machine data extraction is not successful, there is an option (selected at session creation) to fall back to manual data extraction. This generates a ‘text data check’ automatically.

const supplementaryDocumentDataExtraction = new RequestedSupplementaryDocTextExtractionTaskBuilder()    .withManualCheckFallback()    .build(); const sessionSpec = new SessionSpecificationBuilder()    // ...    .withRequestedTask(supplementaryDocumentDataExtraction)    // ...    .build();

Manual Data extraction	Description
withManualCheckFallback	This will initiate manual data extraction only if the automatic extraction fails. We strongly recommend this option.
withManualCheckNever	If the ID fails on automatic extraction, Yoti will not attempt manual extraction and will return a failure in the report.
withManualCheckAlways	The document is always referred for manual review at Yoti's Security Centre, regardless of whether machine data extraction has succeeded or failed.

Filtering documents

You can filter documents by country or by document type.
