“My only complaint is that the outside mailboxes for some reason were locked. It made no sense to me as to why. I was there during regular business hours. The drive thru mailboxes were open so why were the others locked?”

“Love our little post office. We had a po box here years ago and still come by occasionally for shipping. I do love the convenience and that little machine you can use for postage, but I really enjoy talking to the staff here. They’re always friendly, and I especially love the brunette women who greets you with a warm “hi mija.” it just makes the whole experience feel a little more personal ?”

“I prefer the post office that has a self service kiosk in the lobby like the Covina Post Office. Though small and any couple of clerks at the counter, it's been very efficient for me to use.”

“I had a great experience at the Covina United States Postal Service office while helping my husband get his passport for the first time. The whole process was smooth from start to finish. It was super easy to make the appointment online, and when we arrived, everyone was friendly and helpful. The staff made sure we had everything we needed and walked us through the steps clearly. It made what could have been a stressful process feel quick and easy. Thank you to the Covina USPS team for the excellent service!”

“This is a nice post office. Here's my tip for anyone who needs a passport: Many city halls and even public libraries will process your passport. It's worth it to call around and go there instead. You can also start the process online and print out the forms and read about all the things you will need for your passport. In my experience, the post office is the last place I would go for passport needs.”

“Sergio the manager or person in charge definitely runs a tight ship, has all his clerks on check and on point, they have helped me tremendously on all my shipping needs for my business, his mail carriers too do a great job. I've had a few issues here and there but Sergio addresses it promptly anytime I have brought it to his attention. Love this post office, been coming here for years.”

“I am responding to the several selfish, unthoughtful negative reviews posted recently. I have come to this post office for more than 20 years, beginning from the time I was a student at the nearby colleges. I have noticed how USPS head office have steadily reduced the staff, services, and capabilities here while the number of customers has remained the same or grown. Head Office has set up this post office and hundreds more like it to fail. Your unthoughtful complaints are not helping. Meanwhile, staff here struggle valiantly on. I thank them for doing their best in spite of conditions beyond their control. May I recommend before you slam the staff here that you consider writing first to USPS Washington DC and your representatives. Thank you.”

“Effective: There was a notice posted on the door. On Saturday, May 30, 2026, this post office closed. If you need PO service go to 123 W. Holt or the other one farther east on Holt or Arrow Highway/3rd St in Upland.

I liked this P.O. because it was smaller and the staff was very nice, pleasant and courteous.”

“It's a very small post office, right off Irwindale Ave and Arrow Hwy, on a side street directly across from a city park and the Irwindale Police Station. The parking lot has 4 spots, one is disabled only, however, there is parking permitted at it's curb on the street, which is why 4 stars. If you arrive at 2:00pm during weekdays, you'll have to come back at 2:30pm to allow the employees their lunch break. There's also the drive-up out-going stamped mailbox with the Priority Mailbox and Express in the parking area. It isn't as big as the Covina Post Office on Rimsdale or the West Covina P.O. nearby the West Covina Fashion Plaza which may discourage some but I find a bonus for no waiting, generally. It has a handicapped entrance and ramp next to disabled spot. And I've yet to see any of the postal employees being rude or unhelpful to any of the customers and there definitely is no woman by the door asking if you need stamps (really? it's so small, she'd get in the way if she existed) as one review claimed. I just like it because it's quick and easy if I need to go inside.”

You might find what you need here.

They don't have the kitchen sink but they have a billion other items you might need”

“I had a great experience here at this location in regards to their Passport services. Passport services are by APPOINTMENT ONLY. It was super easy to book an in person appointment online through the USPS website. When I arrived, it was busy as usual & there was a line. They separated the lines into two, with passports standing to the side. Per appointments, it went by pretty quick. Christy provided amazing guest service. She was efficient, thorough, friendly and quick. It was my first time applying for a passport and she guided me step by step with ease. They do provide money orders & on site passport photos. I was in and out the post office within 20 minutes. Limited parking in the front. Handicap accessible. Self service kiosk desk available.”

“The supervisor is very helpful and kind, she responds to clients’ concerns and questions promptly. The people under her can be unprofessional and rude sometimes, however, she will take appropriate steps and actions accordingly. Not the most customer friendly staff at the window, so you are pretty much at their mercy and remember to remain polite.”

“I have to admit that the management or system used for 2025 during the busy season (November-December) have improved substantially compared to the last 10 years.

The key thing was keeping the drop off bin free of packages getting stuck especially for those that drop off ton of packages. Otherwise you'll have to wait in line just to drop off which could be worse when there are only 1 employee working the front.

The most annoying thing would be that the outer door can be locked at times before 9am which means you can't access the drop off bin or PO Boxes earlier.”
