On 9/15/20 I mailed several bills at the drive up mail box in front of the Antioch Post Office. Among them was a contribution to the Trump re-election. All mail except the Trump check were cashed. Again on 10/18/20 I mailed several bills at the same location including another contribution to the a Trump campaign. Again, all checks have since been cashed except the Trump check. What is one to conclude about that?


You are a jackass and you did not mail anything.. Trump 2020 got you..hahaa. And leave this post office alone! Great work is being done there!.. the greatest you will ever see! No one does it better

Mail delivered to old address. Unable to receive. Need help !!!!!


Our carrier does not wear a mask when delivering. I believe everyone needs to wear a mask when entering a place of business. Please speak with Zak. Thank you


I appreciate our Antioch Postal Service office. If I walk in or if I call they are always pleasant and kind. They take their time with each person. We really get the small town feeling from our postal workers. Thank you for ALL you do Antioch Post office!


I really appreciate having a post office nearby where the workers are so helpful and congenial. No matter how many people need assistance, they take the time to respond to any inquiries I have and always provide service with a smile. Thank you!!


Clerk 08 interrupted 3 times; never answered my question & assumed she knew what i was asking. She ruined the appearance of my professional mail pieces by slapping on so many stickers (tracking, postage and 2-3 Priority Mail) on the front of the 9 X13 envelope. I use white envelopes and custom address labels so they can be seen and read and present my company with a professional look. I do not use white envelopes with custom labels; so they compete with a sea of crooked stickers applied by a "sticker-slapping-happy" clerk!. When I pointed this out, she even bragged about using so many! This person is clueless about postal piece appearance!
