Where to contact the Illinois Department of Unemployment Insurance
The Illinois Department of Unemployment Insurance (DUI) is the state agency that handles unemployment claims, benefit payments, and wage records. You can reach them by phone, mail, or through their online portal. The main phone line is 1-877-342-6562, available Monday through Friday, 8 a.m. to 5 p.m. Central Time. Wait times are often shortest early in the morning or late in the afternoon.

The portal is available 24 hours a day, seven days a week.

What information to have ready before you call
When you contact the DUI, have your Social Security number and claim number available. Your claim number appears on any correspondence from the DUI and in your online account. If you are calling about a specific issue — a payment delay, a disqualification notice, or a wage record problem — have the date of the notice or the week you are asking about.
If you are filing a new claim, have your driver's license or state ID, your most recent pay stubs, and the name and contact information of your last employer. If you were laid off, have the date your job ended. If you quit, be ready to explain why. The DUI representative will ask detailed questions about how your employment ended, so having these facts straight will speed up the process.
Common reasons to contact the Illinois DUI
People contact the DUI most often to report a payment that did not arrive, to ask about a disqualification or overpayment notice, or to update their address or direct deposit information. If your payment is late, the DUI can check whether it was sent and when it should arrive. If you received a notice saying you are disqualified or owe money back, calling to understand the reason is important — many disqualifications can be appealed.
You may also need to contact the DUI to report that you returned to work, to request a wage record for another purpose, or to ask about a hold on your account. If you are filing a new claim after a previous one ended, the DUI can tell you whether you have enough recent wages to start a new benefit year or whether you need to wait.
If you received a notice that your employer is contesting your claim, the DUI will schedule a fact-finding interview or hearing. You will receive a letter with the date and time. Attending or calling in at the scheduled time is required — missing it can result in a denial of benefits.
How to file a claim online or by phone
Filing online through the DUI portal is usually faster than calling. Go to www2.illinois.gov/idol, create an account if you do not have one, and select "File a New Claim." You will answer questions about your employment history, the reason your job ended, and your work availability. The system will tell you when ready whether you appear to meet the basic requirements. Processing typically takes 7 to 10 business days.
If you cannot file online, call 1-877-342-6562 and ask to file by phone. A representative will walk you through the same questions. Phone filing takes longer because of wait times, but the information you provide is the same. Either way, you will receive a notice in the mail confirming your claim number and your weekly benefit amount.
What to do if you cannot reach the DUI
If the phone line is consistently busy or you cannot get through during business hours, try calling early in the morning (8 a.m. to 9 a.m.) or later in the afternoon (4 p.m. to 5 p.m.). These times typically have shorter wait times. You can also use the online portal to check your claim status, request a payment trace, or submit documents without speaking to anyone.
If you have a specific problem that requires a response — such as a disqualification you want to appeal or a payment error — you can mail a written request to the Chicago office. Include your claim number, a clear description of the issue, and any supporting documents. Request a response date in your letter, and keep a copy for your records.
Some local workforce centers in Illinois also have staff who can help you contact the DUI or file a claim. Search for "Illinois American Job Center" plus your city name to find the office nearest you. These centers are free and do not require an appointment.
Understanding DUI notices and correspondence
The DUI sends notices by mail for important decisions: approval of your claim, your weekly benefit amount, disqualifications, overpayments, and appeals important date. Read these notices carefully and keep them. They contain your claim number, the reason for the decision, and the important date to appeal if you disagree.
If you receive a notice you do not understand, call the DUI and ask them to explain it. The phone representative can tell you what the notice means, what happens next, and whether you need to take action. If the notice says you are disqualified or owe money, you usually have 30 days to file an appeal. Missing this important date can be difficult to overcome.
Frequently Asked Questions
How long does it take to get my first payment after I file a claim?
The DUI typically processes new claims in 7 to 10 business days. Once your claim is approved, your first payment is usually sent within one to two weeks. If you set up direct deposit, the money arrives faster than by debit card or check. If you have not received payment within three weeks of filing, call the DUI to check the status.
Can I file a claim if I was fired?
You can file, but the outcome depends on why you were fired. If you were fired for misconduct — breaking a rule you knew about or were trained on — you may be disqualified. If you were fired for poor performance, inability to do the job, or a reason unrelated to your conduct, you may still receive benefits. The DUI will contact your employer to ask why you were fired, and you will have a chance to explain your side.
What if I disagree with a decision the DUI made about my claim?
You have 30 days from the date on the notice to file an appeal. You can appeal online through your account, by mail, or by phone. An appeals examiner will review your case and may hold a hearing where you and your employer can present information. You will receive a written decision after the hearing. If you disagree with that decision, you can appeal to the Illinois Unemployment Insurance Board of Review.
Do I have to report my income if I work part-time while receiving benefits?
Yes. You must report all income you earn during the week you are claiming benefits, even if it is part-time or temporary work. The DUI will reduce your benefit payment based on your earnings. Some income is not counted — for example, the first $25 per week and 50 percent of earnings above that. Report your income when you certify your weekly claim, either online or by phone.
What happens if the DUI says I was overpaid?
An overpayment notice means the DUI believes you received more money than you were may have access to to. This can happen if you did not report income, if your claim was approved in error, or if you did not report returning to work. You can request a hearing to dispute the overpayment, or you can agree to repay it. The DUI can deduct repayment from future benefits or set up a payment plan. Call the DUI to discuss your options.
