How New Hampshire Plumber license verification works
A Plumber in New Hampshire is licensed by the NH Contractor Licensing Board. When this board is live, PrimaryCheck will query it directly for status, expiration and disciplinary actions and attach the board's record as evidence. Until then the API answers honestly with unable_to_verify and the reason, and the coverage endpoint reports this row as blocked.
What a Plumber license check returns
| Field check | Passes when |
|---|---|
license_number | Equal to the board's number, ignoring prefix and leading zeros |
name | Last name or declared alias matches; first name exact or nickname |
license_type | The record is a Plumber license, strictly (no near-miss types) |
status | The board shows an active status; probation is active with a flag |
expires | Expiration is on or after today, where the board publishes it |
disciplinary_actions | Recorded and flagged with any order documents; never silently dropped |
Verdicts: verified, discrepancy, not_found, unable_to_verify (with a reason), pending. See how verdicts are decided.
