Maryland’s three-month unemployment rate from December through February reached 6.1 percent, a level that allows unemployed workers in the state to receive an additional 13 weeks of unemployment insurance benefits.

The Maryland Department of Labor, Licensing and Regulation said today it is mailing notices to those who may be eligible for the extra benefits. The notice will explain how and when to file a claim. In other words, don't call.

The standard benefit is 26 weeks for Marylanders, but Congress last year twice extended benefits by an extra 20 weeks. The latest increase in benefits will start with the week ending April 18, the state agency said.
