Avoid this Common Error After Signing In

Authorization Failed

If you see the "Authorization Failed" message under Program Status on your MNsure account page, it likely means you already have an active application in the MNsure system. For help with this issue, please call our Contact Center at 651-539-2099 or 855-366-7873.

M002 Error

An M002 error may occur during the account creation process if you have recently moved or changed names. MNsure verifies this information against federal data and recent changes can take a while to be communicated to the federal government. If you receive this error, please try your former address or name. Please note: On the MNsure application itself, you will need to use your current name or address.

Online Service Problems (Blocked or Frozen Credit File)

If your credit report is frozen, we will not be able to verify your identity online and you will see this error message while trying to create an account. You will need to temporarily unfreeze your credit report before creating your account. (See Equifax, Experian or Transunion.)

Or, you can complete the MNsure Account Request form. This method does not rely on credit reporting information.
