Our Newark USPS is conveniently located and has ample parking. Our postal workers, Jamie and Michelle, are excellent at their jobs. They notice when something doesn't look right in the mail or package. When one of these 2 are working, we have great service. The comment by Bay Area Bumpers is accurate that substitute mail carriers may not be as accurate.

Just wondering about procedures for "substitute" mail carriers. Every time our regular mail carrier is off, the substitute ends up not delivering our mail. We are just concerned because the mail may contain something time sensitive. That also means our outgoing mail does not get picked up. Rarely, they make it by 5pm, or a little after, but they do not even go inside to check if there are outgoing mail. We are not ones to complain but we just wanted to raise this concern since it has been happening significantly more often lately. We have absolutely no complaint regarding our former mail carrier, Angelo, and our current regular mail carrier, Paul. They're lovely people. Again, we get concerned about time sensitive mail, especially when our outgoing sometimes ends up left in our outbox for two days, and more when it's a weekend.

I found out this morning that my 'undelivered' package was in fact being delivered to the wrong address, and our postman Chris Romer did a splendid job in retrieving the package to us. Story short, I then realized that I clicked the wrong address when ordering. Please send my compliment to Mr. Romer on my behalf and thank him for the excellent service.

I have been in the office 3 times trying to make an passport appointment. And the clerks only said go online. I explained to online the system not let me make an appointment, but I received no help or good answer from them. I called them and the same answer, “I don’t know mam “. Please we need a better services

It was the second time this week that post crew send wrong mail to my box. Yesterday, I dropped by to return those items, including a small parcel and 4 mails. I remind to your front desk to watch this strange incidence. By yesterday evening, I received another 5 mails belong to other residency. I will make a trip to send those mails back to post office. Please be aware you need to have training for your team. I also makes me worried about the secured way to receive important mail and package through post office. My address is 36795 Spruce St, Newark. I received mails with address 36994 Spruce St.

I called them at 510-797-0903 ant for the 1st time in 2 days of trying to reach them someone answered but guess what...the lady said they do not accept appointments for passport renewal t this number anymore...so she gave me this number 800-275-8777 because that is the new number to set up appointments. I trusted that info and called only to have the other people tell me the Newark lady is wrong. I now have been trying all day to reach the newark location but the line is always busy...I think they're just leaving the line busy on purpose...unless they really have 1 person constantly answering phone...if that's the case then they desperately need to hire a 2nd.

I called to ask about passport renewal and the lady who answered the phone totally shamed me for not doing so sooner if i was traveling next month. She was incredibly rude and i don't care to be treated like that by anyone.

I WANTED TO BRING THIS TO YOUR ATTENTION. WE ARE NOT RECEIVING ALL OF OUR MAIL. THERE ARE BANK STATEMENTS THAT HAVE NOT BEEN RECEIVED. WE CONTACTED THE BANKS & THEY TOLD US THEY WERE MAILED OVER A WEEK AGO. I FEEL SO SORRY FOR THE CARRIERS BECAUSE THEY HAVE TO WORK SUCH LONG HOURS INTO THE DARKNESS AT NIGHT. NO WONDER MAIL ISN'T DELIVERED CORRECTLY. IT'S NOT THEIR FAULT. THE POSTAL SERVICE MUST HIRE MORE PEOPLE TO HELP OUR CARRIERS. ALL THESE NEW HOMES ARE BEING BUILT WE NEED MORE CARRIERS. THANK YOU VERY MUCH MRS. GALLI

This post office is so much nicer than the Fremont one. They are far more organized and less chaotic. They have an appointment system for passports and so you could be sure to be done in 10-15 mins.
