“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.”
“I’ve been coming to this post office for two decades. Always friendly, helpful and to the point. Happy to see my federal tax dollars going to something truly useful.”
“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.”
“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 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 had a great experience the lady who helped me had such a good vibe and was so helpful even with people like me making obvious questions! (Imagine have to deal with that all day)🤣 she didn’t hold back to help! thank you!”
“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!”

“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.”
“I always have a great experience at this Rite Aid! The staff is friendly and super helpful, and they usually have everything I need in stock. I love the variety of products they offer, especially the seasonal items!”
“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!”

“Always friendly, keep boxes in stock, I’ve never had to wait longer than 5 minutes and that was a busy day. Usually walk in and im helped right away. Also parking is very easy.”
“I had an appointment scheduled for later in the day, but Monica was kind enough to take care of me earlier than expected, which I truly appreciated. From the moment I arrived, she was incredibly welcoming, professional, and attentive. She walked me through the entire process with patience and clarity, making sure everything was handled correctly and efficiently.
What stood out the most was her positive attitude and willingness to help—she made what could have been a stressful situation feel easy and manageable. Her efficiency didn’t take away from her friendliness; she balanced both perfectly and made me feel valued as a customer.
Thank you, Monica, for going above and beyond and making my passport experience as smooth, quick, and pleasant as possible. Your excellent service truly made a difference.”
“I have never had a bad experience at this location. The clerks have always been friendly and helpful. In fact I applaud them for working in such a challenging environment. Lack of leadership, at the top, (De Joy), covid, lack of employees, and long hours, have made a very difficult working situation for these people. I think them for their perseverance.”
“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.”
“Great , reliable service, the workers seem passionate, the location is in great condition, the have seasonal stamps, rare stamps, and everyone who works there REALLY seems to be so helpful. Had so troubles with mail delivery, so asked a question and although they sent me to the main office, the lady working ( I didn't catch her name, she has long braids) was truly so helpful, she gave me a 800 number, said call this #, to figure what was going on!
very grateful they are so helpful, recommend this place if you need to buy stamps or get money orders
HAVE BEEN GOING HERE FOR YEARS.
FIRST GAVE 5 STARS, THEN UPDATED TO 3 STARS, HAVE MIXED FEEDBACK, A COUPLE OF THE WORKERS ROCK,
LAST TIME I WENT THERE THE LADY WORKING WAS A LITTLE STRESSED OUT WASNT REALLY ABLE TO EXPLAIN WHY OR WHAT WAS GOING ON, SO JUST TOLD ME TO CALL THE 800 NUMBER.”
“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.”
“Close to work and not too busy. I like to use their machine for self-checkout for mailing packages. Then I stop next door at Contra Costa Coffee for gelato or coffee.”
“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.”
“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.”
“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”
