Golden State Overnight (GSO) was founded in 1995 with a simple notion: that California companies should not be required to pay high national delivery rates for in-state shipments.
Today, GSO offers guaranteed ground and priority overnight delivery to every address in California, and select metropolitan areas of Nevada and Arizona. GSO customers enjoy a premium level standard of service, including later pickups, earlier deliveries and proactive package tracking, as well as unsurpassed customer service and a substantial continued cost savings over the national carriers.

At Golden State Overnight (GSO), we care about keeping our planet healthy and green.

We take that responsibility seriously and are constantly looking for new ways to conserve and promote environmental solutions.
