This map shows the 12,983 post offices that are on the Postal Service’s list for reduced hours under the POStPlan.  Click on a marker for more details.

Red = 2 hours of operation; Yellow = 4 hours; Blue = 6 hours

When it released the list, the Postal Service provided only zip codes, not street addresses, so the markers do not identify the exact location for the post office.  There’s another map, with all the country’s post offices and exact locations, here.

[Google Fusion Tables (with the maps) was shut down on Dec. 3, 2019. A spreadsheet version of the data is here.  A  Carto map with all the country’s post offices is here.]
