Golden State Overnight (GSO), a regional carrier based in Alameda, CA, is now offering guaranteed next-day delivery throughout California and the metropolitan regions of Nevada and Arizona, with a few locations in northern California that will require two days of shipping for packages heading to Arizona.

“Businesses are demanding cost-effective alternatives to the overnight delivery options available through the national carriers,” said Dana Hyatt, president of GSO.

“With GSO Overnight Ground, customers can ship next-day throughout California and much of Nevada and Arizona—paying regular ground rates and receiving a premium-level service, while saving on the numerous fees and accessorial charges that often go unnoticed until the invoices arrive,” Hyatt added.

He also noted that the carrier’s website,, now includes a side-by-side comparison of GSO’s offerings against competitor’s fees and surcharges.
