Where to fax it

One of the 4 Illinois agencies below publishes a fax line for its documents, one runs its program through local offices, so the number is your own county's, and 2 publish only lines for a particular form or an appeal. Call the number in the row before you send.

The office asks for your case number on every page. Put it on every page you send, and keep the fax receipt. An office that cannot match a page to a case has to set it aside, and the receipt is what proves you sent it before the deadline.

Call before you send. Agency fax lines change and some stop answering. A short call confirms the number and whether that office is the one holding your case.

Medicaid renewals
Illinois Medicaid Redetermination Project

The Department of Healthcare and Family Services asks for the name and case number on every page sent for a Medicaid-only redetermination, and asks the sender to keep the fax confirmation.

What the fax costs on FaxTerra

This is what FaxTerra charges to send it. It is not a fee the office charges.

Free pages reset on the 1st. If a second packet in the same month takes you past 10 pages, a FaxTerra Lite pack covers it, with no subscription.

Questions

What do I put on every page I fax to a Illinois agency?

Your case or client number, your name, and your date of birth, unless the row below says the office asks for something else. A page that arrives without a case number has to be matched by hand, which is the slowest path through any agency.

Can I fax a Illinois agency without a fax machine?

Yes. Upload the pages from your phone or computer, enter the office's fax number, and send. The agency receives it as a fax. Every account gets 10 free pages a month, and a page to a US fax number counts as one.

What if the fax line does not answer?

Call the number in that office's row before you try again. A line that rings and never connects will not start working on a retry, and the office can tell you whether the number changed or whether it wants the document another way.

My row says the program runs through county offices. Where do I fax it?

To your own county office, whose fax is in the state directory linked in that row. Illinois does not run that program from one address, so there is no statewide number to give you, and a number from another county will not reach your caseworker.

Is this an official Illinois site?

No. FaxTerra is a fax service. Illinois and the office you are writing to set the rules and decide your case; every number and requirement here is linked to the agency's own page under official sources.
