If you're collecting unemployment benefits in Illinois, filing your initial claim is only the first step. To keep receiving payments, you must certify — a recurring process where you confirm your eligibility for each week you're claiming benefits. Understanding how Illinois certification works, what's being asked of you, and what can affect your payments helps you avoid mistakes that could delay or interrupt your benefits.
Certification (sometimes called weekly certification or biweekly certification) is how the Illinois Department of Employment Security (IDES) verifies that you remain eligible for benefits after your initial claim is approved. Each certification period, you're essentially answering: Was I still unemployed, available to work, and actively looking for a job during the week(s) in question?
Illinois processes certifications on a biweekly schedule — meaning you report for two weeks at a time, rather than week by week. IDES assigns you specific filing days based on your Social Security number. Filing outside your assigned window can delay payment.
Illinois claimants certify through the IDES online portal or by phone through the Tele-Serve system. The online option is available around the clock during open certification windows; Tele-Serve has specific operating hours.
During certification, you'll typically be asked to confirm:
Answering these questions accurately matters. Providing false or misleading information during certification can result in an overpayment, disqualification, or fraud penalties.
Illinois requires claimants to conduct a minimum number of job search activities each week to remain eligible for benefits. As of recent program rules, claimants are generally required to complete at least three job search activities per week — though this can change based on program updates, labor market conditions, or individual claim circumstances.
Qualifying activities typically include:
You're expected to keep records of your job search activities, including employer names, contact information, dates, and the type of activity. IDES can request this documentation at any time. Failing to meet job search requirements — or being unable to document them — can result in a denial for that certification week.
If you worked part-time or earned wages during a certification week, you're still required to report that income. Illinois uses a formula to determine how part-time earnings affect your benefit payment for that week.
Generally, Illinois allows claimants to earn a certain amount before benefits are reduced dollar-for-dollar — but the specific calculation depends on your weekly benefit amount (WBA), which is set based on your earnings during your base period. Reporting wages accurately each week is required; underreporting can trigger an overpayment.
| Situation During Certification Week | Effect on Payment |
|---|---|
| No work, met job search requirements | Full weekly benefit typically issued |
| Worked part-time, reported earnings | Partial benefit — calculated based on WBA and earnings |
| Worked full-time or exceeded threshold | Benefits typically not payable for that week |
| Failed to report earnings | Potential overpayment and penalties |
| Did not meet job search requirements | Possible denial for that week |
Illinois has historically required a waiting week — the first week of an otherwise eligible claim for which no payment is issued. This week must still be certified; it simply isn't paid. Not all states have a waiting week, and Illinois has waived it during certain periods (such as during the COVID-19 pandemic), but under standard rules it applies.
A few patterns consistently cause problems for claimants:
Certification is the ongoing part of your claim, but several underlying factors shape what actually happens when you submit:
Illinois claimants who are denied for a specific week can appeal that determination through IDES's appeals process. Outcomes vary depending on the specific facts of each case.
The certification process itself is straightforward — but whether your responses result in a payment, a hold, or a denial depends on your individual claim history, your work activity, and how your particular case has been adjudicated.
