“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!”

“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.”

“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.”

“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 ?”

“There was a queue, but the lady behind the counter was courteous, friendly, patient, yet very efficient.
It was such a joy to watch her work, I didn't mind rejoining the queue when I was done putting my packages together.
If every business had a Kwana (I hope I spelled her name right?), this world would be a much better place!”

“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.”

“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.”

“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.”
