The Postal Service is considering closing more than one in 10 of its retail outlets.
The financially troubled agency was announcing Tuesday that it will study more than 3,600 local offices, branches and stations for possible closing.
In D.C., nineteen locations have been placed on the list. Dozens have also been targeted in Virginia and Maryland. For a state-by-state list, click here.
Currently the post office operates more than 31,000 retail outlets across the country, down from 38,000 a decade ago, but in recent years business has declined sharply as first-class mail moved to the Internet. In addition, the recession resulted in a decline in advertising mail, and the agency lost $8 billion last year.
Some of the offices that face review are in rural areas, but postal officials say they are looking into alternative service, such as locating offices in local businesses, town halls or community centers.
In those cases the so-called Village Post Office would replace one to be closed.
