You can find your ten digit Maryland Employer Account Number on any notice received from the MD Department of Labor, Licensing and Registration, Division of Unemployment Insurance. You can also find it on your Unemployment Insurance Quarterly Contribution Report (FORM DLLR/OUI 15) or at the top of your annual tax rate notice that's mailed by the agency in December of each year.
