I don’t think they check the drop box outside. I dropped something off Tuesday night and still today almost the end of Thursday it’s not updated so I’m going to visit in person because ive had a package they lost after I dropped off in the drop box outside. Also the phone number is disconnected. Can you guys get it together?

Hours are incorrect, the website says 10:00am, I’m here and they aren’t open. Someone should fix this. It’s also the slowest post office I’ve ever been to with just one employee to help everyone— expect long lines and wait times—or go to UPS store instead because they can do a lot of what this office can, in a fraction of the time, and their hours are legit.

Small office but employees are on top of it and not too long of a wait time. Carolina was really helpful

Everybody please note that the AC post office opens at 2:30pm (not 2pm) for the afternoon hours, per the sign on the door. Google and every other is wrong when they list 2pm as the re-open time.

always packed and slow, hours don’t work for anyone unless unemployed. Need to hire another worker.

Pretty sure at this point some postman are stealing packages
Not sure if this place also handles outgoing mail but this review is for whoever handles delivery in the 94503 area code
Today i was waiting on a package to arrive it was shipped by ups with hand off to local usps ups passed it on friday to local usps with them saying delivery for saturday.
Well sure enough i get alerted that usps dropped off my package at 1030am at my front door despite the fact me being home and not seeing the truck or any kind of knock or ring at my door so they cannot claim its package thieves
This is the 3rd time within a year this has happened and other peoole in my house hold same thing for a total of 6 non delivery of packages within the past year
Now like last time its gonna be damn near impossible to get a refund or redilvery of item because as long as usps missing package rep or the vendor sees left at front door or left in mail box despite no signature or pic of the package they just brush it off
So be aware if you live in the 94503 area code there’s a chance your postman will not deliver your package or most likely have issues with theft

The American canyon post office is the worst of any post office in the United States for the last two years I have not received my veterans benefits check for weeks after the first this month it's the 6th and still not delivered the delivery person doesn't put mail in the right box do they even speak English or know numbers I know the checks get to the post office before the first for delivery why does it take 7-10 days to get to the Mail box the post office should be closed down it's not sufficient for mail delivery i now have to get in touch with the US Treasury to find my check

The hours online are NOT updated. It says open 1-2pm I came back at 2pm to find out they don’t open until 2:30 wasted time and inconvenience. Fix this

I've hated on the post office since I was 17 yrs old, what an inadequate "business". They hire people who barely contain their contempt for customers, an idiot & political lacky General Postmaster DeJoy was put in office with his agenda to slow down the mail, now first class mail takes 10 days to be delivered, high rates, lousy service. Extorting fees to just have a mailing box that gets stuffed with JUNK mail first and all kinds of rules you better not break or else!!!!Specifically, however! American Canyon Substation has a pretty awesome staff, so USPS did something right, keeping this tiny little place open and available!

I think the few employees I have met do a fairly good job. The hours and size do not work for this city nor its working citizens. I am retired, but the hours are too short even for me.
