Can't get address right...even though I have a PO Box!! Lost packages. Returned mail to sender instead of putting it in my box. Doors are never open until 6pm to collect my mail. They really should change the hours on the website so more people don't waste their time going just to find the door locked. Very frustrating.


This is the second time our mail was opened, my child has a pen pal who sent her a small shopkin in envelope and it was stolen out of the card. You can never reach the post office by phone bc it is always busy and we are still getting mail from 3 different previous owners after complaint twice. Get it together Fishkill.


This post office is awful. The employees are rude. Our mail carrier is completely useless, unreliable and a liar to boot. She hangs packages on the side of the mailbox in plastic bags in snow storms, or balances them on top of the mailbox, or delivers to the wrong house. I consistently receive mail for other people. In the 10 years I've lived here I've had nothing but disappointment and problems with this post office. If you need something shipped use fed-ex or ups, I know I will.


Fishkill Post Office does not have all the priority prepaid boxes that are available.. A postal employee that works the front desk in Fishkill, a woman with blonde hair, gets very annoyed if a customer inquires about the availability of a box size that is not on the box shelves. Asking for tape, which the USPS used to supply free for priority packages, REALLY annoys  and she stage whispers to a coworker "Can you believe she's asking for tape?".
 The boxes can be ordered for free through the web site and they will pick up the package for free. This is great service that saves a trip to the post office and saves the public from dealing with a miserable employee.
