WHY POSTALSURE

Most residency checks stall between a deliverable mailbox and proven habitation. PostalSure is the evidentiary record layer in between: carrier DPV normalization, county parcel deeds, household roster alignment, and field confirmation unified on one schema, so your risk team audits facts instead of reconciling scattered bureaus.

Three instruments built on
one record.

One console for postal deliverability, household corroboration, and field custody. Every carrier lookup, utility header, and disposition score lands in the same immutable trace.

4-Stage Evidentiary Provenance

From raw street string to
sealed chain of custody.

Every stage appends UTC-timestamped evidence without overwriting prior observations, giving underwriting, escrow, and compliance officers complete replayability.

STATE 01 · VERIFIED

Corroborated Habitation

Carrier DPV/RDI flags, property and utility registries, and any scoped field visit align with the declared street unit and adult roster without material contradiction.

STATE 02 · DISCREPANT

Contradictory Evidence Cited

Independent records or physical threshold inspection directly conflict with the declaration—such as an undisclosed CMRA mail drop, vacant unit, or divergent household links.

STATE 03 · UNVERIFIABLE

Explicit Evidentiary Boundary

Where rural highway-contract registries or restricted building access prevent independent confirmation, PostalSure documents exact coverage limits rather than guessing.

Operational Questions

Clarity before you
verify a record.

Returning applicants and invited record holders can retrieve their active verification file directly via the Record Portal.

How does PostalSure differ from standard CASS/DPV address hygiene?

Standard CASS/DPV lookup only confirms that a physical mail receptacle exists along a carrier route—it cannot tell whether the address is a commercial mail receiving agency, an unoccupied apartment, or inhabited by an unrelated household. PostalSure unifies carrier deliverability with parcel ownership, utility headers, household corroboration, and optional on-site confirmation.

When does the Verification Policy trigger an on-site field visit?

Most files clear deterministically through Stage 02 registry linkage in milliseconds. Stage 03 on-site field confirmation is dispatched only when documentary sources conflict, sub-unit numbering is ambiguous, or your underwriting policy requires physical occupancy verification under a 48-hour SLA.

How are conflicting or thin rural records reported?

PostalSure never masks uncertainty behind synthetic scores. Conflicting sources produce a Discrepant disposition citing each contrasting timestamp and registry, while sparse rural coverage or locked-lobby limits produce an Unverifiable disposition itemizing exact data boundaries.

Can we monitor verified files for post-closing relocation drift?

Yes. Enabling Quarterly Drift Watch attaches longitudinal monitoring to the sealed baseline hash, alerting your servicing team when NCOA forwarding orders, parcel deed transfers, or utility disconnects indicate household movement.
