“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!”
“Hey! If this is your flag which I think it is because of POW flag, is time to change it. The flag is split into two and that's a nono. Jun 2025, two months later on a visit, new flag, thank you.”
“Aihua was extremely friendly, professional, and helpful while assisting with passport applications for my two daughters. She made the process easy, smooth, and stress-free. We truly appreciate her outstanding customer service. Thank you, Aihua!”
“I don't mind going to this post office especially since I live so close. I can't say I haven't had my share of problems with them, but it is the post office and sometimes thats to be expected. Generally when I go I'm in and out as opposed to other larger ones. I wish parking was better, but downtown Clayton is pretty small”
“I was so nervous to get my first passport, but Dean made the process super simple and straight forward! Very happy and thankful I went to this location and got helped by him!”
“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 completely forgot my old school id two days ago when i picked up my package and i just got it in the mail today! i didn’t even hit anybody up for it! a+ customer service thank you very much”

“The Lafayette post office is a great place for your needs. And their customer service is awesome. They got above and beyond, to make sure their needs are met at their business. Thank you.”
“Shout out to YVETTE! I normally dread going to the post office, but she made my experience so special. She has wonderful, personalized service, a constant smile and works with the customers to ensure they’re getting the best price possible. Goldstar employee!”
“Ruth was very kind and helpful here! She's an excellent employee. She saved me $50 today by finding a spare box in the back so that I didn't have to use the XL size they had in stock. The XL would have cost $74 (and was too big for the stuff I had to ship), but the box she found only cost me $24 to ship. Thank you Ruth!”

“Thank you David for having a smooth transaction with you. I ask an envelope and without hesitation you gave me one and you explained the normal envelope and the priority one. You're kind to me and you have patience of answering all my questions.
Thank you for helping me.”
“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!!”
“They were incredibly helpful. I mean, they’re always great, but they helped me work out which box to use, and they were spot on! I like these simple pleasures, like friendly, helpful people.”
“They don't answer the phone because they don't have one here unfortunately, they have really long lines, and the only good thing about this office is they are helpful and are nearby where I live so I can send packages”
“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 ?”
“The bad reviews worried me but at least in my experience today it was totally fine. Rang the doorbell, lady came out quickly, I explained my issue with my package not being delivered to my home, she found it and gave it to me. Easy as that.”
“This is a great post office! It's unfortunate that their reviews don't reflect it.The staff is always incredibly helpful. And they have a lot of patience in dealing with helping people with their packaging. I've never seen a look of contempt from any of them. In fact the opposite. 5 Huge ? ? ? ? ?”

“Passports! I had to get passport renewals for minors, and that can only be done in person. It was impossible to get an appointment anywhere, but they do walk-in passport applications here!!!
Here is what I learned and my pro tips:
-walk-in appointments MWF 9-10am ONLY
-They only take the first 20 people… (I don’t know if that’s actually just the first 20 passport, but I don’t think it’s groups)
-If you’re number 21, you’re gonna have to come back another day
-If you wanna make sure you are in that first 20, you need to get your rear end there *** early*** (the line was about 30 people along by 8:30 AM today)
-don’t think that you can show up at 9 AM and be fine, at least not at this time of year
-Come with everything already completed
-Use black ink only
-Better yet fill out your application online and print it out
-Don’t worry about passport pictures, they take them there and charge $15
-They take check or debit card for passports. No credit cards.
-They’re strict and very busy, so bring your patience, be polite and be humble to their process
-if you are eligible to renew by mail, just do it and save yourself the hassle
The lady that helped me was very down to business, but awesome! I think this post office is great, they’re all nice and helpful.”
“I don’t know there are such bad reviews, I had a lovely time if you can getting my postage and packages out. They were very friendly, quick and informative. A machine was broken and they were very apologetic.”
“Excellent service, the lady was super nice and sweet ?, never judge a book by it's cover y'all. They may look angry but they aren't. Doesn't mean you have to be rude yourself ? Patience ?”
“Applying for my son's passport here was a breeze. Filled out all the details online and came here with right set of documents and took the photo at the facility. Overall it took 15 minutes at the facility and received the passport in 4 weeks.”
“**America is still alive!!!**
I had the absolute best customer service experience in at least the past 5 years at the San Ramon USPS Post Office – hands down the most outstanding and stupendous service I've ever received from any business.
During the chaotic Christmas week, a delivery attempt was made to my closed office on Christmas Eve (Wednesday). With Thursday being Christmas Day, I waited until the next business days – Friday the 26th and Saturday the 27th – but there was no sign of my package. After calling USPS customer service, I was told it should be at the San Ramon location.
I went in and explained the situation to an older African-American clerk (I regrettably forgot her name). She was incredibly patient and helpful from the start. When the package couldn't be found initially and I mentioned how important it was – a discontinued, very expensive product – she went completely above and beyond. She searched multiple areas thoroughly and even escalated it to the supervisor.
It turned out there was a scanning issue after the Christmas Eve attempt; the package hadn't been properly logged back into the facility or was still on a truck. They took my contact info and promised to call. Just 10-15 minutes later, while I was driving home, I got a call from Supervisor Will – he had the package in hand! Even though the post office was closing, they invited me to come right back so I could pick it up that day.
This level of dedication and genuine care simply doesn't exist much anymore. They turned a stressful holiday mishap into a complete turnaround, saving my Christmas week entirely. I can't express enough gratitude to the wonderful clerk and Supervisor Will – you restored my faith in people.
In places like this San Ramon USPS, the real America I grew up in is still very much alive. Thank you from the bottom of my heart!”

“My husband and I just received such high quality service it honestly amounted to concierge level service from Ali who processed our expired passport renewal. We arrived without an appointment (you can make an appointment but they will try to serve you if they can even without an appointment,) Ali took our photos, processed the forms and in ten minutes at most, we were all set and out the door. Best of all was Ali’s professionalism and friendly attitude.
UPDATE: On the above review and an added exceptional experience. We applied for our US Passport renewals with Ali at Alamo USPS on July 15, 2025. We received our new Passports Aug 13 and 15, 2025. Great service time.
On Aug 15, 2025, I took my 95 year old aunt in for passport renewal of her expired passport. Ali helped us. His patience and professionalism were superb. Great staff at Alamo, USPS office.”
