Illinois Registered Agent: verify the record, then decide

The official source for Illinois Registered agent records

Every listing on this page is an official government register: coverage is evidenced by the register's own pages, never asserted. Ordering is a printed rule, not a rating: registers with a verified official fee first, then by verified-fact count, then by name.

What to know before you search

Verify before anything else. The official search linked in the table shows the current agent of record for any registered Illinois entity; that lookup is the authoritative answer, and it is where you confirm a change actually landed after any filing.

Illinois still runs corporation and LLC records as visibly separate series in one search, and its fee schedule is unusually public: the charges sit in the Business Corporation Act itself rather than a rate card.

If you are choosing an agent for your own company rather than checking someone else's, the trade-off is the same in Illinois as everywhere: serving as your own agent puts your street address on the public record and ties you to business hours, while a commercial service sells coverage and privacy. The referral below is disclosed where it appears, and the register facts on this page do not depend on it.

Searches for this page also arrive as "registered agent illinois"; same register, same record, same evidence standard.

How do I find out who a company's registered agent is in Illinois?

Search the entity in the official register (Illinois Secretary of State); the agent of record is part of the public listing. The link and the register's verified facts are in the table above.

Can I be my own registered agent in Illinois?

Generally yes, with a street address in Illinois and availability during business hours; your address becomes part of the public record. Our guide on whether an LLC needs a registered agent walks the decision.

How do I change a registered agent in Illinois?

File the state's change-of-agent route with the new agent's consent, then confirm the new agent shows on the official record; the register, not a service dashboard, is the proof. Our change-of-agent guide covers the steps.
