Efficient, Friendly, and Always Reliable! I’ve had consistently excellent experiences at the Flanders Post Office. The staff here go above and beyond to make every visit smooth and pleasant. Whether I’m dropping off packages, buying stamps, or asking questions about shipping options, they’re always courteous, knowledgeable, and quick to help.

it is Monday, 11/12/18. I went to pick up my mail from my PO box. I reached the post office at 4:30PM. The doors were locked even though the lobby was supposed to be open until 5PM. I drove 30 minutes and ended up wasting my time and gas...
