### What this is

Contractors, subcontractors, suppliers and architecture and engineering firms register with the Capital Development Board to work on State of Illinois building projects. The Board publishes each registration with its trades and expiration 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 Illinois 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 Illinois Capital Development Board, and not a certificate. Individuals and names without a company word are left out. Only registrations not yet expired are shown.
