Structure the input before you verify
A reliable bulk workflow starts with a state, license number, and contractor identity for each row. Keep the original input beside the normalized response so reviewers can see what matched and what changed.
- Normalize state codes and preserve leading zeros in license numbers.
- Separate exact-number verification from business-name discovery.
- Record when each check ran and which source supplied the result.
Route exceptions instead of hiding them
Bulk verification is most useful when obvious matches move quickly and ambiguous records enter a review queue. Define outcomes for no match, multiple matches, identity mismatch, inactive status, and stale or incomplete data.
- Do not treat a missing field as approval.
- Recheck records on a schedule appropriate to your risk policy.
- Confirm consequential decisions with the licensing authority.
