What it entails

Identity Checks examine SSN formatting and death records tied to SSN.

Why it works

A fraudulent SSN may not be correctly formatted, or not found in our records. A SSN with a death record, while valid, cannot be used in many cases.

The following are the distinct IDs and types of checks that are included in the Identity Check Package.

SSN validity

Value	Name	Description
`INVALID_SSN_FORMAT`	Invalid SSN format	The SSN is malformed or impossible under SSA assignment rules.
`NO_AUTHORITATIVE_MATCH`	SSN has no authoritative match	The submitted SSN was not observed from an authoritative source.
`NO_KNOWN_SSN_FOUND`	SSN not found	The submitted SSN was not found in known graph data.

`TRUE`	Identity is deceased	The submitted SSN is marked as deceased.
`FALSE`	Identity is not deceased	The submitted SSN is not marked as deceased.
