Directory cards sometimes show a CSLB license number, and sometimes they do not. When a number is shown, it is labelled 'stated by business' — meaning the business states it on its own website or listing, and this directory has not re-checked it on the CSLB website. That distinction matters, because a stated number and a verified number are different claims.
The only way to confirm a license is to check it yourself on the CSLB website before hiring. That check takes a few minutes and answers the questions a directory card cannot: whether the license is current, what classification it covers, and whether it belongs to the business you are hiring.
How to check on CSLB
- Go to the CSLB license check on cslb.ca.gov.
- Search by the license number shown on the card, or by the business name.
- Confirm the license is current and the classification covers the work you are hiring for.
- Confirm the business name on the license matches the business you are hiring — not just a similar name.
What a missing number means
A card with no license number does not mean the business is unlicensed. It means the directory has no business-stated number to show. Some trades and firms are licensed under a different structure, and some listings simply do not state a number. The CSLB check is still the right step before hiring.
Questions people ask
Is a stated number worthless?
No — it is a useful lead for your own check. It is simply not a verification, and this site never presents it as one.
What if the number does not check out?
Do not hire on the strength of the card. Ask the business directly, and consider another provider. A mismatch is a reason to pause, not to proceed on trust.
License verification pending — confirm with CSLB before hiring, unless a license number is stated by the business itself. Any license number shown is stated by the business, not verified by this directory.
