“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 can’t say enough good things about this post office. Every single time I walk in, I’m greeted with genuine warmth and kindness. Adriana, Anne, and Jose are absolute gems — each one of them is so friendly, patient, and makes you feel truly cared for. They go out of their way to be helpful, and there’s such a comforting, positive energy every time I visit.

What also really stands out is how much effort they put into decorating for every holiday. It’s those little touches that make the place feel so welcoming and special. Going to this post office honestly feels like visiting family. Thank you all for making a routine errand feel so warm and human. Highly recommend this location to anyone who wants great service with a smile!”

“I didn’t know I would write a review for USPS. Everybody was so nice and thoughtful. I walked in for a passport. Made a few mistakes, but was in and out within 5 minutes. Even took passport photo and staff made sure I like the picture. My nearest USPS has a bad reputation. I’m so glad I drove extra to this location. Thank you everybody who helped me out!”

“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 ?”

“Haven't been there IRL, but from the service I get from deliveries. I can't help but give them 5 starts — they work their butts off no matter how if it rains or if it's ungodly hot or cold. These guys are always here for us, they're one of the back bones of America! Keep up the amazing work mail(men/women) of USPS Covina! You guys are amazing”

“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!”

“Best USPS!!! The workers there are always friendly and always give a little treat to my package helper (kids ?). They go above and beyond and are so patient with all the packages I drop off. ??”

“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.”

“After failing to find my packages in my mailbox for quite some time, I went to the front desk for assistance. I was advised to purchase a P.O. box, which I did; however, my packages were still missing.
When I returned today, an absolutely wonderful staff member—a woman named Kamal—helped me out. I panicked because a package delivered today contained medication, and although I overreacted, she handled the situation with great understanding. She contacted the person who had delivered the box to inform him of the issue—a man named Mark—and he immediately met me at the mailboxes to assist me. He was incredibly understanding and patiently demonstrated, step-by-step, that my key was actually opening the wrong box. It turned out my previous shipments—and everything else—were right where they belonged. Given how stressed and agitated I was today, I was extremely pleased and grateful to encounter two employees who were so helpful and understanding.
My deepest thanks and appreciation.✨✨✨✨✨⭐️⭐️⭐️⭐️”

“Scanned my box right away and gave me a receipt as the good lord intended. No disputes over the weight, no telling me to take my box and go. I recommend this location over Eureka because there are competent staff here and not at Eureka.”

“Just a shout out to our awesome postman, Larry Cashman. He works very hard, always delivering our mail timely, even though he has a pretty sizeable delivery area. He's the best we've ever had and we wanted to let him know how much we appreciate him. Always has a smile and a friendly greeting!!! He is the best!!!”

“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.”

“January 8, 2026
I have been extremely happy with the very recent new, well-skilled and pleasant postal clerks who have been added to this location. Veretta has always been excellent and friendly and I have not seen Anh in a very long time who was also very good but these new ones at the front counter are beyond a wonderful needed and welcomed change here. A huge thank you to the one who made and followed through on this decision. Thank you. Please keep them there!?”

They explained everything thoroughly and ensured my documents were safely packaged. The service was quick, professional, and the prices were very fair, especially for the quality I received. I’m so grateful for their help, and I will definitely return for all my mailing needs.”

“Often a positive experience every time I come to the post office :) There’s often a line, but it moves quickly. The new scanning machine helps me avoid long lines for when I just need to scan a pre-purchased label.”

“The staff were very welcoming. Since my English isn't good, they guided me through each step of the filling process and even used simple colors to help me complete the payment. It was so heartwarming and efficient.”
