How South Dakota Plumber license verification works

A Plumber in South Dakota is licensed by the SD Contractor Licensing Board. PrimaryCheck looks the license up live at the board's public verification system (board lookup) by license number, or by name when no number is supplied. The record the board publishes is captured as evidence, hashed, and rendered into a proof PDF.

Fields returned for this board: name city license_type license_types expires page section.

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
