“Great experience at the USPS Diablo location! This charming, historic post office is nestled between golf courses in a peaceful country club setting. I had a passport appointment and was in and out in 10 minutes. No lines, and the staff member was friendly, efficient, and even took my photo on-site. It's a small post office with just one staff member, but everything ran smoothly. Hidden gem for passport services!”

“Great service, convenient location I'm glad was not closed, though one time a package was not picked up from here (to be shipped) on the same day even though I dropped it off before the cutoff time. That was years ago and it's only happened once out of multiple times, so I think it's alright.”

“I never thought I would give a USPS location a high rating, 'til I came to this one. They're so friendly and helpful. I was trying to mail a couple of packages and surprised by the cost going to the other coast. I didn't even say anything but the lady there was so nice asked what it was and offered me cheaper mailing options. She even gave me the supplies to repack my packages. And I saw them even offer tape to help someone seal their package better. Can I just say Wow, that's so nice! Usually you get someone very moody behind the counter at other locations that would tell you to buy your own tape. This location is a USPS gem.”

“This Post Office is located in the San Leandro Plaza and is open on Saturdays!!When I do have to mail a package, this is where I go!! The main reasons for that is that they usually have multiple windows open and they are open on Saturdays, the only day that I really have time for this. Now, sometimes on said Saturdays there's a long line here, but it moves along decently.The postal workers here are friendly and polite also!!”

“My recent visit to the US Postal Service for a change of address was a mixed experience. The process itself was fairly simple and efficient, which was a relief. However, my observation with the Customer Service left me with conflicting feelings.

On the one hand, the representatives were undeniably friendly and welcomed each customer but on the other hand, I couldn't shake off a disconcerting incident I witnessed. While waiting in line, I overheard a customer, whose native language wasn't English, seeking assistance regarding fragile items. The customer selected yes, when they should’ve selected no on the keyboard. Unfortunately, they were advised by the representative to bring their own interpreter if they couldn't communicate effectively in English. This struck me as somewhat insensitive and disappointing.

While I understand the practical challenges faced by the establishment, it's crucial for them to offer language services to accommodate diverse customers. Expecting individuals to bring their own interpreters seems impractical and burdensome. The availability of toll-free numbers for language assistance should be actively promoted and utilized to ensure equal access to services and although this would require additional steps, it’s something all establishments should do.

Overall, the US Postal Service seems to strive for kindness, friendliness, and professionalism, but there's room for improvement in addressing language barriers and ensuring inclusivity.

On a positive note: I really enjoyed their large selection of greeting cards and the person who helped me was supper kind in explaining the process of changing my home addresses ?”

“I want to say, the staff is so kind and professional at this location! I lost a receipt a few weeks ago, and I couldn't see her name but the lady on the very right hand side booth bent her back trying to get my receipt I lost. Literally so kind and professional. She didn't seem annoyed at all and the nicest. I can't thank her enough for the help she gave!”

“I love this post office. The sistah that works in the far corner is so incredibly helpful and proficient at her job. She is so on it, that I usually leave feeling better than I walked in because she makes the experience so pleasant and clear. If it weren't for parking I would use this post office exclusively. I will say that the USPS should update the equipment. Some of the machines seem like they haven't been updated since before Regan was president.”

“Ramon rocks and is the glue that holds this post office together. Not sure what we'll all do when he retires. But, I wish him the best of luck when he does and thank him for all of his helpful service over the years.”

“Went to the post office to ship a package and mail some letters. I arrived a little after 11:30 and the line was out the door. It took about 15 minutes before I was served. Maybe 10-10:30 is the golden hour. It would be nice if there was a dedicated parking lot, but I have a feeling the majority of patrons are walk-ups. I appreciate their constant cleanliness, knowledgeable employees, and their constant stock of domestic and international stamps.”

“I came in for a Passport Walk-In. It’s honored between 11-12 Tuesday thru Thursday. I was there by 8:45 am and was the first one in walk in. By 9:30 I was called and taken care of. We were greeted and asked to wait in line. Then when they had no other customers, they started processing the walk-ins and were very efficient. They had very good knowledge about passport services. Overall other customers were also taken care of very nicely and with great customer care.”

“I would like to say Thank you so much MARIA for helping me. 10 star for you. Maria was so accommodating, nice, kind, and she has a long patience. I have a big box to send overseas and she approached me and help me without any hesitation.

Honestly, there's a few staffs that should help me but they went all at the back of their office so Maria can take my big box which was not fair to MARIA. By the way God bless you Maria and to other staff who doesn't want to help me cause they don't want to carry the big box well then shame on you Guys.

To clarify, this is April 12 2025 transaction only so who ever work on that day then shame on them except MARIA who helped me to carry my big box.

I also want to thank you the other Lady she's quite Old Asian who borrowed me a trolley cause I can't lift heavy stuff. If you read this Thank you so much.”

“This post office is located on MacArthur Boulevard down the street from where I live. They normally have two to three workers at one time and I haven't had too many problems coming here to buy money orders and stamps. Lunch is from 12:00 p.m. to 1:00 p.m. so normally there's one person working at this time.”

“After trying several zip codes to find a passport appointment, I used OAK Airport's zip code and got what seems to be the only appointment in the bay area for the month of February. I arrived for my appointment 15 minutes before and was helped right away by David, he was great, attentive, polite and very helpful. I rarely leave reviews but this location has so many negative ones I had to comment with my experience and help this post office because there was literally nothing to complain about. Thank You for the help David, as a brand new American citizen and applying for my first United States Passport you made it a breeze.”
