newark and fremont are two different cities right next to each other. the warehouse i believe is actually located within the city limits of newark, but right on the border. Fremont is the larger of the two and easier to identify. if you make any long distance calls or local toll calls to the area, it will be listed as "Fremont/Newark" on your telephone bill.
if anything is coming from newark or fremont, onvia means the same warehouse, but the cities are actually two seperate cities.
