Understanding Match, No Match, Partial Match and Unable to Verify

Overview #

Verification results are often misunderstood. A result is usually a comparison between supplied information and available source information. The outcome may be a clear match, a clear no match, a partial match, or an unable-to-verify outcome.

Why it matters #

Decision-makers should avoid treating every non-match as fraud. Errors, old records, spelling differences, maiden names, data capture mistakes, timing delays and source availability can all affect the result.

How to think about it #

• A match means the supplied data aligns with the reference data used for that check.
• A no match means the supplied data does not align with the reference data under the matching rules applied.
• A partial match means some attributes align and others do not; this usually needs review.
• Unable to verify means the check could not be completed or the source did not return enough information to support a result.

Common examples #

• A person changed surname after marriage but the source still carries the previous name.
• A qualification was recently issued but not yet reflected in the relevant verification process.
• A document image is unreadable, causing data extraction errors.
• A source is temporarily unavailable or a manual turnaround is required.

Responsible use reminders #

• Do not make high-impact decisions on ambiguous results without a review step.
• Keep a record of the matching rule and the data submitted.
• Give affected people a reasonable opportunity to correct inaccurate information where required.
