What Is the Michigan Workers’ Compensation Phone Number?

The main phone number for the Michigan Workers’ Compensation Agency is 888-396-5041. That toll-free line reaches the Workers’ Disability Compensation Agency (WDCA), which oversees the state’s workers’ compensation system under the Worker’s Disability Compensation Act. If you know which part of the agency handles your issue, calling the division directly is faster.¹

Direct Numbers for Every WDCA Division

The WDCA is split into divisions, each with its own line. Dialing the right one the first time avoids the transfer loop.

Which Division Handles What

A few of these lines come up more than others. The Compliance and Employer Records Division at 517-284-8922 is the number to call if you need to know whether an employer carries the workers’ compensation insurance Michigan law requires, or if you believe an employer is operating without it.²

Claims Processing at 517-284-8912 handles questions about new and pending claims. The Funds Administration Division at 517-284-8888 manages the Second Injury Fund and the Silicosis, Dust Disease, and Logging Industry Compensation Fund, which cover specific categories of occupational illness and prior-disability situations.

If your claim is already in dispute, the Board of Magistrates at 313-456-3650 is where contested cases go for a formal hearing after mediation. The Workers’ Disability Compensation Appeals Commission at 517-284-9312 is the next stop if you want to challenge a magistrate’s decision.¹

What to Have Ready Before You Call

WDCA representatives can only pull up your file with precise identifying information. Gather this before you dial:

Your Social Security number, which is the primary identifier in the agency’s system
The exact date of injury, not an approximation
Your employer’s legal business name as it appears on your pay stub or W-2, which often differs from the trade name
Your treating physician’s name and contact information, so the representative can match medical records to your claim
Any existing claim or case number from prior correspondence

If you’re reporting a new injury, the representative will likely walk you through the Employee’s Report of Claim (Form WC-117), which initiates a workers’ compensation claim.³ The form asks for your SSN, date of injury, employer name and address, and a description of how the injury happened.⁴ You can submit it electronically or mail it to the WDCA at P.O. Box 30016, Lansing, MI 48909.

When You Don’t Need to Call at All

Some things are faster online. The WDCA website has a public Insurance Coverage Look-up tool that tells you instantly whether a specific employer has active workers’ compensation insurance, so there’s no reason to call for that.

For document filing, the agency uses a File Transfer Service (FTS) as its secure portal for claim forms, insurance documents, and applications for mediation or hearing. The Health Care Services Online Reporting System got a new interface in February 2026 and uses MiLogin for access.⁵

Deadlines That Make the Call Urgent

Two separate deadlines govern Michigan workers’ compensation claims, and missing either one can sink the case. If you’re calling the WDCA about an injury, know where you stand on both.

You must notify your employer of the injury within 90 days. The clock starts on the date of injury or the date you knew (or reasonably should have known) you were injured. Late notice doesn’t automatically kill a claim, but the employer can defeat it by showing the delay actually prejudiced their ability to investigate.⁶

You then have two years to file a formal claim with either your employer or the WDCA. That window runs from the date of injury, the date the disability first appeared, or the last day you worked for the employer, whichever is latest. If you were physically or mentally unable to file during that period, the deadline extends until two years after the incapacity ends, and it pauses while you’re receiving benefits or favored work from the employer because of your disability.⁶

Even inside the two-year window, back benefits have a separate ceiling. You generally can’t collect compensation for any period more than two years before the date you filed a hearing application, and nursing or attendant care is limited to one year of back recovery.⁶

If Your Claim Is Disputed

If the carrier questions your right to benefits, it must file a Notice of Dispute (Form WC-107) with the WDCA within 14 days of the employer learning about the injury, and you’ll receive a copy at your address on file.⁷ A WC-107 doesn’t mean the claim is dead. It means the carrier has raised a question that needs resolution.

To move a disputed claim forward, either side files a written application with the WDCA stating the nature of the dispute. The agency may route the case to mediation first. If that doesn’t resolve it, the case goes to a formal hearing before a workers’ compensation magistrate, who issues a written decision.⁸ Call the Board of Magistrates at 313-456-3650 for hearing questions and the Appeals Commission at 517-284-9312 to appeal a decision.
