If you're trying to reach Michigan's unemployment agency, you're dealing with the Michigan Unemployment Insurance Agency (UIA) — the state office that administers unemployment benefits, processes claims, handles appeals, and manages employer accounts. Knowing which number to call, when to call it, and what the agency can and can't do for you over the phone can save you significant time and frustration.
The UIA operates under the Michigan Department of Labor and Economic Opportunity. It is the single state agency responsible for:
Michigan's unemployment program is state-administered but federally framed — it follows rules set under the Federal Unemployment Tax Act (FUTA) while applying Michigan-specific eligibility standards, benefit calculations, and procedures under the Michigan Employment Security Act (MESA).
| Contact Purpose | Phone Number |
|---|---|
| Claimant inquiries (general) | 1-866-500-0017 |
| Employer inquiries | 1-855-484-2636 |
| UIA Advocacy Program (claimant assistance) | 1-800-638-3994 |
| Fraud reporting | 1-855-468-0427 |
Hours of operation for the main claimant line are typically Monday through Friday, though wait times and availability can shift during high-volume periods. Michigan's UIA website — michigan.gov/uia — is the authoritative source for current hours, as these change periodically.
The Advocacy Program number is worth noting separately. Michigan operates a UIA Advocacy Program staffed by state employees who can assist claimants who are having difficulty navigating the system — not legal advocates, but trained staff who can explain processes and help identify next steps.
Many claimants find the Michigan Web Account Manager (MiWAM) faster than phone contact for routine actions. Through MiWAM, claimants can:
MiWAM is accessible through the UIA's official website. If you haven't registered, you'll need your Social Security number and Michigan driver's license or state ID. First-time users set up an account before accessing claim functions.
Calling the UIA directly is useful for some things and limited for others. Agents can generally:
Agents cannot:
If you receive a determination you disagree with, the appeals process — not a phone call — is the formal mechanism for challenging that decision.
If the UIA denies your claim or reduces your benefits, you have the right to appeal. Michigan has a two-level appeals structure:
Appeals are filed through MiWAM or by mailing a written request. The UIA's main claimant line can confirm that an appeal has been received, but the appeals office operates separately from the claims processing side.

For appeals-related inquiries specifically, contacting the MCAC directly — rather than the general claimant line — is typically more effective once a case has advanced past the first level.
Michigan closed its walk-in UIA offices to the public following the COVID-19 pandemic and has largely maintained a phone-and-online service model since. However, the agency does accept written correspondence at:
Michigan Unemployment Insurance Agency P.O. Box 169 Grand Rapids, MI 49501-0169
Written submissions are appropriate for formal requests, document submissions that can't be uploaded digitally, or correspondence related to fraud, overpayments, or legal proceedings. Keep copies of everything you mail and consider using certified mail for anything time-sensitive.
Employers contesting a claim, responding to a separation inquiry, or managing their UIA tax account use a different contact channel than claimants. The employer line (1-855-484-2636) routes to agents who handle employer-side functions — rate notices, account management, and formal responses to claim notifications.
When an employer contests a claim, that protest triggers a separate adjudication process. Both the claimant and the employer may be contacted separately during that process, and determinations are made based on information submitted by both parties.
Getting the right contact information is straightforward. What's more variable is what happens once you make contact — and that depends heavily on:
The UIA's contact channels are consistent. The process, timeline, and outcome that follow depend on the specifics of your claim, your work history, your former employer's response, and how Michigan's eligibility rules apply to your particular separation.
