Baltimore and the Chesapeake region
410 is huge for a city code: Baltimore and its suburbs (Towson, Catonsville, Pikesville, Glen Burnie, Columbia, Elkridge), the state capital Annapolis, and much of the Eastern Shore across the Chesapeake Bay, including Salisbury. That’s why it lists 102 rate centers, far more than any other code in this list.
