STICKER - 510 (Area Code) 2.3"

From the artist:

"The only area code I've ever had. The number 510 is so valuable as it is a rare area code to now have. This number covers East Bay communities in Northern California including Hayward, Oakland, San Leandro, Alameda, Richmond and more. Due to the growing population, a new area code "341" as been introduced to new phone lines issued in the region.

"Fun Fact: From 1947 until 1991, Oakland was included in the 415 area code. Now it's only available to folks in San Francisco."
