Professional and occupational licenses in California are issued by state licensing boards — each profession has its own board with its own search tool. There is no single database of all licenses in California.
What this page covers: California professional license verification databases — medical, legal, real estate, contractor, financial, and other regulated professions. What it does not cover: Business entity filings (those are with the Secretary of State) or association memberships (those are private organizations).
Where to start: Identify the profession, then go to the specific licensing board for California. For attorneys, go to the state bar. For doctors, the medical board. For contractors, the contractor licensing authority. The databases below are organized by profession.
Common mistake: A professional license and a business registration are different. A license authorizes a person to practice a profession. A business registration authorizes a company to operate. They are filed with different agencies.

Frequently Asked Questions
Where do I verify a California professional license?▼
Most California professional and occupational licenses (medical, legal, contracting, real estate, cosmetology, etc.) can be verified through the Official California Professional & Occupational Licenses at www.dca.ca.gov. Look for the 'License Lookup' or 'Verify a Licensee' tool — searches are typically by name or license number and return active/inactive status.
How do I apply for a California business license?▼
California business licensing combines state, county, and city permits depending on activity. The Official California Professional & Occupational Licenses at www.dca.ca.gov is the primary state portal; local business-tax certificates are issued by the city or county where you operate. The federal usa.gov permits guide is a helpful starting overview.
Is a California license required to work in my profession?▼
That depends on the profession. California, like most states, licenses regulated occupations such as healthcare, legal, construction, real estate, cosmetology, security, and many trades. The Official California Professional & Occupational Licenses publishes the full list and exemption criteria at www.dca.ca.gov.
How do I report a complaint against a California licensee?▼
Complaints against licensed professionals in California are filed with the issuing board or division under the Official California Professional & Occupational Licenses. Most boards accept online complaint submissions at www.dca.ca.gov, plus mail-in forms. Each board reviews complaints under the standards in California's occupational code.
Does California recognize licenses from other states?▼
Many California boards offer license-by-reciprocity, license-by-endorsement, or expedited pathways for applicants already licensed in another U.S. jurisdiction. The Official California Professional & Occupational Licenses at www.dca.ca.gov publishes the reciprocity rules per profession; some require additional California-specific exams or jurisprudence tests.
