How to verify a contractor license

A license number printed on a website is a starting point. The next step is finding the relevant official record and understanding what it says about the company and the work you are planning.

Find the right authority

Licensing requirements depend on location and type of work. Identify the state or local authority responsible for the relevant trade. Start from an official government website rather than relying solely on a directory’s description.

For example, California’s Contractors State License Board lookup supports searches by license number and business name. This is a California resource, not a nationwide licensing system.

Match the company you are hiring

Compare the official record with the name on the proposal. If a brand name differs from the contracting entity, ask the company to explain the relationship. Do not assume that a similar name proves it is the same business.

Save the lookup address and the date you checked. If the authority provides information about status, classification, or disclosed complaints, read those fields rather than stopping at the fact that a record exists.

Ask what the record means for your project

Write down anything you cannot interpret and ask the licensing authority or a qualified professional. Useful questions include:

• Is this the entity that will sign the agreement?
• Does the relevant credential cover this type of work?
• Are other trade licenses or permits relevant to the proposed scope?
• What should I check again before work begins?

Keep the evidence in context

A license check does not answer every question about a contractor. It does not, by itself, tell you how the company communicates, whether it is available for your schedule, or whether the proposal is complete.

Combine credential research with references, a clear written scope, and direct conversations. Home Review Board does not issue contractor licenses; any license information on a company profile should identify its source and be checked for current status.
