Came here to finally get the kiddos their passports. Fast service and very friendly. Glad they do walk ins and don't require an appointment like all the surrounding post offices. read more

I was waiting for a package to be delivered but tracking said it was being held a the post office because they could not leave the package in a "secure delivery location". No one even attempted to deliver to the door. My husband was home that day at the time it was SUPPOSED to be delivered. I had called the 800 number and tried the automated service to request a re-delivery, and went through all the damned options, and at the end the automated system finally told me that my package was no longer available for re-delivery. I selected the option to talk to a live person. So I talked to a live person finally after a 20 minute hold and they told me where the package was. My husband went to go pick it up TODAY 4/13/17, and although it says they will hold the package until the 15th, they could not find the package. "We attempted to deliver your item at 9:57 am on March 31, 2017 in MONTCLAIR, CA 91763 and a notice was left because no secure delivery location was available. You may arrange redelivery by using the Schedule a Redelivery feature on this page or calling 800-ASK-USPS, or may pick up the item at the Post Office indicated on the notice beginning April 1, 2017. If this item is unclaimed by April 15, 2017 then it will be returned to sender." My husband's reaction: "They are just too f@ckin' lazy" "And they wonder why nobody wants to use the US mail anymore!" I agree. I almost went postal on the postal service... pun intended. lol read more

We like the services the Montclair post office provides. They are always pleasant, busy and extremely hard working. Our mail carrier is the best b/c he delivers in all kinds of weather, cheerfully which is why these carriers deserve air conditioned trucks ...(?)... A while ago I thought abt our carrier and felt bad that he 'd be delivering in such hot 116 degree weather, I worried a little but hoped he'd be fine as are the other postal people out there would be. In closing I say , we love our Montclair Post office. Thank You !! I partially posted this b/c I want to stick up for these guys . read more

First time visiting and TOM K. was my sales associate. This was BY FAR the BEST customer service I've experienced from a USPS office, and on top of that it was busy! I noticed the camaraderie between the workers and it positive, respectful, and contagiously happy. This will be my go-to office moving forward. Wish I would've known about this location a long time ago! Way better than Upland office. read more

Read all the reviews and majority of them are the same issue I had, not once but thought the years. I had a passport appointment at 11:15, took work off & headed there just to get there and tell them I was there for a passport appointment. Keep in mind I live in Fontana & every appointment in my city was beginning April. I only found one appointment middle of March in Montclair! I took it and made the drive. She continues to tell me she called out sick and I said do you guys not call to reschedule or let people know? She said the should've, but obviously reading these reviews nobody does. I asked if I can come back when she's back to work she said no reschedule online with the biggest attitude, asked to speak to a supervisor. The supervisor was just a rude didn't even give me the option of coming back or apologizing for the inconvenience. I asked am I able to come back when shes back to work and just show them my confirmation appointment I received via email? She said "yeah" nothing more. So if they cancel your appt without a heads up YOU ARE ABLE TO GO IN WHENEVER THE PASSPORT PERSON IS BACK & SHOW YOUR APPT EMAIL AND DO THE APPT THE SAME DAY THEYRE BACK. Do not let them tell you otherwise, very unprofessional & inconsiderate of other people time. read more

This office is a prime example of why people hate the Post Office and why it is going the way of the Dodo bird and Pony Express. They never answer the phone. Our carrier could not, for the span of two months, seem to figure out the difference between our apartment number and our neighbors, and they reported a certified letter sent to me signed for and delivered when I never laid eyes on it. The only seemingly functioning part of this office is the supervisor Frank who will go above and beyond to fix the bumbling idiocy of his inept staff. read more

The little post office that could. Small, but super efficient, and staff is very helpful and courteous. Tom the passport guy is awesome and rushed my family of five right on thru the process. Stark opposite to the horrible #uplandpostoffice. read more

No parking, long lines, only 2 windows open, rude employees, outrageous prices, filthy store and slow shipping times!

This place sucks. Mail came today and my text alerts said my package was out for delivery. Mailbox had mail but no package and no delivery notice. No one answers the phone at this location, doesn't matter how many times you call. And you can't get a hold of anyone with the 800 number either. WTF USPS? read more

I went there because my package said it got there when I tracked it and the worker named sandy who.asian I think was very rude not helpful at all so I left came back another day and Keli was outstanding and helped me 100 percent and I recommend to go to her if she there I read on yelp about a rude worker an I'm positive its sandy thank u for ready send feedback thanku read more

I really appreciate Frank holding my packages so that I could pick them up since I have been having issues with my packages not being delivered to the correct address. I don't know what's going on with my regular mail carrier but hopefully this won't become a regular thing. Thanks again, Frank! read more

Got my passport here in February and it got to my house in 2 weeks! Very fast! In addition, every time I send out mail, I get great customer service and it's fast! read more

Very good staffs! Especially Tom, he is making everyone who walks in with a happy mood leaving, fun chat and helpful information/material that he seems to very skilled to provide the clients. read more

Update. I was finally able to get the Postmaster Tom on the phone and his carrier swears the item was delivered but failed to scan it and show it as delivered. Tom says the "counseled" his driver about scanning every item with tracking info. I just had to refund my customer $54 because the driver didn't do his job. Someone needs to step in and find out why this happens so often at this location. (judging from other reviews about items failing to be delivered) I am disgusted over this whole incident read more

Good service, depending on what time and day of week you go it's usually not too crowded. Close to my work and convenient, parking is quick also read more

Tom who works the front desk always brightens my day. I always hope he's the one who calls me up from the line. He's the best. He's basically the reason for the 4 stars. Someone broke into the PO Box and stole some sensitive stuff, so that's a concerning and the reason for the a four star review versus a five star review. read more

Very fast and friendly services. We needed to process passports and Montclair's post office accepts walk-in appointments. John was very informative and helpful. Tom was funny and very helpful with the process. I recommend anyone who lives within the area to experience their services for themselves. read more

Sometimes the service at this post office is terrific but sometimes it's not so terrific . Concerning package deliveries it all depends on who the carrier is on any specific day if it goes well or not . Usually Monday thru Friday we have our regular carrier and package pick up and delivery goes pretty smoothly . However if a replacement carrier is filling in on Saturday or if our regular carrier is on vacation then there's only a 50 / 50 of getting our bigger packages delivered to our door . I had a package out for delivery according to the tracking number last Saturday containing a birthday gift for my youngest son . It was very important that it arrived on time . The trouble started because the package was deemed undeliverable stating a problem with our address according to the tracking information . No I don't think so , since we have packages delivered here all of the time I believe the '' problem '' is because we had a different carrier . Now I have no idea where my son's gift is and nobody answers the phone at the Montclair post office . Not happy read more

Sandy is horrible. Did not give me my package because it "wasn't there" the next day I went she said I had ur package here yesterday. She's very rude. read more

Fast, friendly service. I ship items from this office nearly everyday, and have never had a problem.

I will NOT do business with this Post Office....they always botch my order and the lines are long and SLOW.....the mail carriers are always so nice ...One of them used to deliver mail where I lived his name is Tom, he is a gentleman very nice guy.... read more

people are unhelpful - be careful of out side mail drop off boxes as I've recently had mail lost/stolen never delivered. growing number of homeless at night hanging around outside and inside of this office and in the park across the street at all hours - trash and needles can be seen regularly at this location. read more

This particular post office, or at least the people that deliver the mail are liars. They said they attempted to "deliver" our package but said no one was home and left a message. Both are lies. They neither rang the door bell, which it does work, and didn't leave a notice. Two people at least are always on premises so they can't say they tried. No wonder people don't like to use them. Wish another company could deliver mail so they can show how incompetent of a organization USPS is. read more
