MiUI Minute: Issue 17

The Michigan Unemployment Insurance Agency (UIA) is transitioning to a new tax and benefits system called MiUI, which will replace the current Michigan Web Account Manager (MiWAM). In this issue of the MiUI Minute, we’re providing information about your employer account number in MiUI vs. MiWAM.

MiUI Employer Account Number

How is a MiUI employer account number different than account numbers in MiWAM?

The employer account number (EAN) is the system ID number for each employer account in MiWAM and in MiUI. The EAN in MiUI has a few key differences from MiWAM:

• The EAN is the simplest way for UIA staff or third-party administrators (TPAs) to find an employer account in MiUI through the various search functions.
• The 7-digit EAN will be used to initiate a MiUI account at Go Live on Feb. 23, 2026. More information on the MiUI account initiation process will be provided soon. 
• If an employer account changes status (i.e., reimbursing, contributing, terminated, reactivated), the account will maintain the same EAN. An employer will no longer use multiple EANs, which is the case in MiWAM.
