If your Wisconsin unemployment claim was denied, the next move is usually boring but critical: file the appeal and ask for a hearing. You do not need a legal memo. You need a request that reaches the UI Hearing Office before the 14-day deadline runs out.
The Wisconsin Department of Workforce Development accepts appeals three ways. Pick the fastest one you have access to, and keep proof of how and when you filed.
Where the appeal goes
All first-level Wisconsin unemployment appeals are routed to the UI Hearing Office within the Wisconsin Department of Workforce Development. The address, fax line, and portal path are the same no matter where in the state you live.
Online: dwd.wisconsin.gov/uiben/appeals-and-petitions.htm
Mail: UI Hearing Office, P.O. Box 7975, Madison, WI 53707
Fax: (608) 327-6498
Phone (for filing help, not the appeal itself): (608) 266-8010
The three filing methods
1. The claimant portal (fastest)
Wisconsin allows online appeals directly through the claimant portal you already use to certify weekly. This is the fastest path and the one we recommend when the deadline is close — submission is time-stamped the moment you confirm. Keep a screenshot of the confirmation screen.
2. Fax
Send to (608) 327-6498. Receipt time is the transmission date on the fax confirmation sheet, not the date someone at DWD prints it. Save the confirmation sheet.
3. Mail
Send to UI Hearing Office, P.O. Box 7975, Madison, WI 53707. Wisconsin treats a mailed appeal as timely by postmark, so the date the postal service stamps the envelope is what matters — not the date DWD opens it. If the deadline is within a few days, use certified mail and keep the receipt.
If your determination letter lists a specific address or fax that differs from these, use what the letter says. Wisconsin sometimes routes appeals to the hearing office identified on the determination. The notice controls.
The nine-digit number that controls everything
Every Wisconsin unemployment determination has a nine-digit determination number printed on it. Whether you appeal online, by fax, or by mail, you need to identify the determination by that number. It tells the UI Hearing Office which decision you are appealing, which is not obvious if there are multiple determinations in your file.
If you cannot find the number, look near the top or bottom of the first page of the determination. Most workers also have it in the portal under their claim history.
What to actually write
There is no magic sentence. Wisconsin just needs your appeal to make one thing obvious: you are appealing the determination and you want a hearing. If you are filing by mail or fax, a short signed letter is enough. Something like this works:
“I appeal the determination dated [issue date], determination number [nine-digit number]. I disagree with the decision and request a hearing. My name, mailing address, and phone number are below.”
Include your full name, the last four digits of your Social Security number if your state asks for it, your mailing address, and a phone number that will still work when the hearing notice arrives. Save the longer story — what happened, who said what, the documents — for the hearing itself.
Five things to do right after you file
- Save proof. Portal confirmation, fax receipt, or certified mail receipt. The deadline trap is procedural; your proof is the answer to it.
- Keep filing weekly claims. If you stop certifying, you can win the hearing and still lose weeks of back pay.
- Watch for the hearing notice. Wisconsin sends a hearing notice with a date, time, and call-in instructions. Wisconsin first-level hearings are usually by phone.
- Register your phone number and any interpreter needs as soon as the hearing notice arrives. Missing the call is treated like missing the hearing.
- Build the evidence packet: timeline, emails, attendance records, text messages, witness names. If your employer appealed, gather the records that show why you should qualify.
What if my employer appealed instead of me?
You still need to participate. An employer appeal can put existing benefits at risk, and a Wisconsin administrative law judge can reverse a determination that originally paid you. Watch for the hearing notice, register your phone number, and gather the same evidence you would gather if you had appealed yourself.
