- JMJackeline Lopez MartinezMay 22, 20261.0Not sure why, but every single experience I’ve had at the Castroville Post Office in the last 15 years has been negative. Customer service matters, and unfortunately there hasn’t been one experience where staff spoke in a respectful or professional tone. Customers deserve to be treated with basic kindness and courtesy but sadly you won’t find that here.
- DGDalilah GutierrezMay 16, 20262.0When filling out passport information and you make a mistake DO NOT use whiteout. Clerk had advised to use it. When the process started at another post office it was said "You're NOT supposed to use whiteout."

- SSSergioJan 19, 20261.0Awful customer service not helpful & extremely rude for no reason
- CMChristy MunozSep 18, 20255.0I've always had great experiences when I'm dropping off packages to be mailed even if I get there at the last minute. They are super sweet 💜🫶🏼💜
