You never know what you will get when visiting this place, some of the employees are friendly while some of them are rude or simply don’t give a damn. So good luck, you will need it.

This review is long overdue, but my experiences with the Union City post office have consistently been positive.
My local mail carrier and truck driver are friendly, dependable, and regularly go the extra mile to hand-deliver my packages.
As a collector of plushies, pendants, figures, and all things cute, I receive a high volume of deliveries, and they’ve always been handled with care and attention.
Although I don’t know their names, their dedication and reliability truly stand out.
I’d also like to recognize Chris, the manager/supervisor at the Union City post office. He has always been professional, courteous, and proactive when providing updates—especially when packages are delayed or temporarily misplaced. (For some reason, many shipments tend to stall in California—go figure! 😅)
Visiting the post office has generally been a pleasant experience. The staff is patient, respectful, and willing to help with questions or concerns.
I understand that others have had different experiences, but I can only speak from my own.
I’ve lived in Union City my entire life, have interacted with this post office countless times, and continue to have consistently positive experiences.
Overall, the Union City post office has been reliable and professional, and I’m grateful for the care taken in delivering packages to my household.
Cheers! 💌📦

Just a heads up, things are really slow and outdated here. There is no Kiosk and the workers are clearly overworked. I’d avoid this USPS. It took 1 hour to send a package.

Great service. Joshua helped me track down a package that didn’t get delivered. Very helpful and professional. I didn’t catch his colleague’s name but she was also very kind.
