Interpretation of MobileMatch
Interpreting the results of a standard MobileMatch verification.
Overview
Verification via MobileMatch is represented at the top level by a policy decision (true for all transactions on the AXN). You can confidently engage business logic based on only the policy decision, but understanding the underlying outcomes at the assertion and component levels will enable you to engage in more nuanced business logic and help users troubleshoot.
Recommended Reading
You'll need to understand policy decisions and the process for finding and reviewing an individual transaction before attempting to analyze an individual transaction, which is what's covered here.
Assertions/Components
For standard MobileMatch, the verification process is two steps: PII verification followed by OTP verification. Since there are multiple paths through which a user can pass through PII verification and since users can be Denied at either step, it's helpful to understand each underlying component independently.
Standard PII verification uses two policy components (level 1): the "PII" component is based on four sub-components (level 2) with their own sub-components (level 3) and assertions. The "Risk Checks" component is based on four assertions. Standard OTP verification uses one policy component (level 1), the "Phone access indicator (OTP)" component which is based on one assertion.

Notes
A) MobileMatch is unique in that it can and does attempt to connect a full name to a phone number any way possible, as direct as name-to-phone or more indirectly such as name-to-address-to-phone. This increases the number of potential assertion payloads.
B) What may seem like undue complexity in the MobileMatch policy is actually there to accommodate the multiple vendors capable of returning an individual assertion within the AXN; what is presented as one assertion here (e.g. link.lastName_phone) actually represents x3 assertions, hence why these assertions are organized into one component so one policy can accommodate multiple vendors.
