How to verify a CIDB contractor

Start with a CRS number or contractor name. Search GradeCheck to find the closest match, then confirm the contractor's registration status, expiry date, and full grading history before shortlisting.

The final verification step is always the source CIDB page. Every contractor profile on GradeCheck links back to the captured source record so you can validate the result at the point of decision.
