One particular mail carrier who delivers to River Valley Ranch, white female with long greyish/dirty blonde hair, has been NOT wearing her mask inside the mailbox room at the Ranch House. A few weeks ago, the door was open while she was unloading the mail, and I walked in to find her unmasked. I asked her to mask up, and she was belligerent with me, stating that she's been vaccinated - as if that was reason enough to not mask up inside. She clearly does NOT know that she could still get infected AND leave respiratory Covid-19 droplets and aerosols behind that infect others. I stopped by the Ranch House today, and she was unloading the mail, again unmasked, and this time with the door closed. It is NOT acceptable that she does not wear a mask inside a small space, and in this case, with no ventilation. NOT acceptable.


Last collection time of 3pm for Carbondale on Saturdays is incorrect. It is now 1pm. This caused me to waste two hours of my time for a drive to Carbondale today. Please try to keep info on the web pages current.


USPS delivery drivers has gotten lazy by the days. I pay for priority mail and this guys say attempt to deliver hold for pick up, but my security camera says otherwise. They do not attempt to deliver the items on time.


This post office has the worst delivery system I’ve ever seen. I rarely get my Packages delivered when they note on tracking they have been delivered. So many times I have to reach out and wait and some days or weeks later the package will finally appear. I’ve lived in many states over the years and this city and it’s postal delivery persons must be totally ill funded because they can’t manage to get letters or small items into the correct mailboxes in Carbondale


My neighbors and I are having a horrible time with our mail - it gets delivered to the wrong address, packages do not arrive at all, or arrive empty.


I don’t know if this office is understaffed or just not efficient. I’ve always had problems from the local office in the 3 different locations I’ve lived in Carbondale, and I decided to get a box, hoping that if they didn’t have to sort it to a truck, it would be faster. With a post box, the mail seems to be slower than ever. Furthermore, it was better when UPS delivered my packages when I lived 3 miles outside of town, and now that I live in town, USPS is delivering, but it takes 2 extra days for everything. I’ve also tried to deliver things through this office, and besides Marty, everyone else is gruff, terse, and incredibly angry to be working there. It’s worse than TSA!


This P.O. has been just great!! good operating hours and helpful and friendly and efficient counter staff. Home deliveries impeccable! Thank you for a daily service that is dependable and happy.


On Friday, July 8th, all of my mail was delivered to the wrong address by the mail carrier. The next day, a small box addressed to me was delivered to the ground next to the alley. I tried calling the local postmaster (81623) but the phone was constantly busy. This is the first time in 25 years that have felt the need to complain.
