This location is a sorting substation for mail carriers of the United States Postal Service. For pickup of mail and other services, customers should go to the post office at 220 South Livermore Avenue, or to the contract substation at the Chevron gas station next door. That said, it is a great place to take a toddler who loves mail trucks, because there are dozens of them on the property. There is also plenty of parking for the public as well as friendly mail carriers who do not mind answering questions about their job.
