Eventually, I replaced those with just a 650 cell phone, but 50% of the numbers I dialed I still had to dial the 408 area code.

crazy. but that wasn't until the 90's. 408 was in the 50's it says. i stayed 415 from 60's to 90's! i do remember being irritated when they finally changed us around. had been that way forever.

What kind of amazes me is that Silicon Valley never got it's own area code. Rather then being divided between 415/650 and 408. You would think the tech companies would all demand to have the same area code. Instead of them overlaying 669 on 408, it could have become it's own area code stretching from Palo Alto to Santa Clara.

Very interesting and informative .

Thanks for posting this.

I hadn’t remembered when during the 80s 619 was created (now I have a point of reference ).

One of my Bay Area numbers is a cell number that I’ve had since the 90s from a company that at that time was ‘basing/homing’ the numbers from what I understand was a cellular only ‘exchange number (the three numbers after the area code)’ to the 925 area code, and if it showed up on a landline bill, it would list the location as ‘Pleasanton’. Assignment of location was important to some people (not me, but to some people I’d talk with on the phone) at the time because they might be charged ‘message units’ if calling from a landline. IIRC, the company that I started that number with was Cellular One. I thought I started that in 1996, but it’s always been a 925# so, with your info, I know it was 1998 rather than 1996 or earlier.

A new area code is coming for Los Angeles County: 738.

Today there are 10 area codes in L.A. County, and in about eight months, there will be an 11th: 738, which will cover the same territory now served by 323 and the much-diminished 213.

This is why we can’t have nice things: Landlines may be going the way of the fax machine — in fact, AT&T wants to end its duty to provide wired phone service to anyone in its California service area who asks for it — but the population of cellphones and other connected devices that require phone numbers continues to grow. So the area served by 213 and 323 is, believe it or not, running out of unassigned numbers.

The California Public Utilities Commission approved a proposal last year to add 738 to the mix as an overlay, meaning that it will be used in the same turf as 213 and 323. “The 213/323 area codes generally serve the downtown portion of the City of Los Angeles and the surrounding cities and communities, including Alhambra, Bell, Bell Gardens, Beverly Hills, Commerce, Cudahy, Glendale, Hawthorne, Huntington Park, Inglewood, Lynwood, Maywood, Montebello, Monterey Park, Pasadena, Rosemead, South Gate, South Pasadena, Vernon and West Hollywood, as well as unincorporated portions of Los Angeles County,” the CPUC* helpfully explained on its website.
