Collection agency license required?	Yes — Illinois generally requires third-party collection agencies to hold a state license, registration or bond, at least for consumer debt.

These are general rules for orientation only; limitation periods depend on the contract, the type of debt, where suit is filed and events like payments or acknowledgments. Licensing rules often differ for consumer vs. commercial debt and change over time. Confirm with the Illinois regulator or a Illinois-licensed attorney. This is not legal advice.

Should I use a collection agency or a lawyer in Illinois?

For most past-due accounts, a collection agency is the first step: demand letters, calls and negotiated payment plans, usually on contingency. If the debtor disputes the claim, ignores the agency, or the balance justifies litigation, a collection attorney licensed in Illinois can file suit in the appropriate Illinois court and, after a judgment, use the state's enforcement tools such as garnishment, levies or liens. With a 10-year general window for written contracts, it pays to act well before deadlines approach. See collection agency vs. collection attorney.
