### What this is

Businesses that collect or owe a City of Chicago tax — amusement, parking, ground transportation, hotel, lease, use tax and others — register with the Department of Finance. 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 Chicago 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 City of Chicago, and not a certificate. Individuals and names without a company word are left out. Sole proprietors are left out. The record ID is made by this site from the name and address.
