The United States Postal Service at 1941 California Ave is a busy post office that handles a large volume of mail and packages. It is part of the USPS network, which delivers to every residential and business address across the country, managing over 30,000 retail locations and processing almost half of the world's mail. The staff is generally helpful if customers have everything ready to ship, but there can be long lines and limited help at the counter, often with only two associates available. Customers are advised to prepare their packages fully, including labels, to avoid returning to the end of the line. For simple tasks like buying stamps, self-help machines are available in the lobby. The delivery system is praised for its speed and accuracy, especially for outbound packages sent by a small business, with a high rate of correct deliveries. However, reviews mention that residential and incoming mail deliveries are less reliable. Some concerns have been raised about the security of the pull-up mail drop box, with reports of a sticky rat trap found inside, posing a potential risk to mail. Overall, the post office provides essential services, with a mix of helpful staff and occasional issues, emphasizing the need for preparedness and caution during visits.
Understaffed Line barely moves. You spend 30 min to ship at pick up something. Ridiculous

The entire staff and mail delivery person located in Corona on California Ave were very helpful, courteous and professional. I appreciate them for providing superior customer service.
