### What this is

Businesses operating in unincorporated Marin County hold a County business license. The County publishes the active ones with their type and issue date. This site keeps the companies — names that carry Inc, LLC, Corp and the like — and makes them searchable by name, type and place.

### Who uses it

- **Suppliers and landlords** — is this company in the Marin County file, and since when?
- **Sales teams** — companies by type and place, and the newest ones.
- **Owners** — your own record as the source publishes it.

### What it is not

Not the County of Marin, and not a certificate. Individuals and names without a company word are left out. The County file covers unincorporated areas; cities such as San Rafael license their own businesses.
