I've seen allusions to it in a couple of articles, but missed any
direct discussion...
Pacific Bell recently announced (in my phone bill which came today)
that Alameda and Contra Costa Counties (Oakland, CA, and vicinity)
will be split from the rest of Area Code 415 (San Francisco &vic.)
on October 7, 1991, into Area Code 510.
Does anyone know why we get 510, when there are still N0X/N1N codes
available (not many, but still 909 and 917 off the top of my head)?
Also, any particular reason for starting with an old Western Union
code? Now that we've unleashed the great flood of possible area
codes, will there be a rush to split more NPA's? I looked through
an atlas a while back and saw several areas that were pushing the
population figures at which splits seem to take place.
For anyone interested, here follows the text of Pac*Bell's note:
415 area code SPLIT
Beginning October 7, 1991, Alameda and Contra Costa Counties will have
a new Area Code, 510. San Francisco, San Mateo, Marin and parts of
Santa Clara County, as well as the islands in San Francisco Bay will
retain the 415 Area Code. An easy way to remember this change is to
think of San Francisco Bay as the Area Code boundary.
The new Area Code is necessary to provide phone numbers for new
customers in this expanding area.
If your business is located in Alameda and Contra Costa Counties,
remember only the Area Code will change. Your 7-digit local telephone
number will remain the same as will your local toll-free calling areas.
Our change of Area Code may affect the operation of some of your
programmed telephone equipment. In particular, automatic dialing
devices, speed calling services, alarms and mobile phones may need to
be reprogrammed. Your equipment vendor will be able to advise you,
whether your telephone equipment needs to be reprogrammed.
As you order printed materials, such as new letterhead, advertising,
and business cards, please keep the October 7, 1991, change in mind.
We will send you another reminder as the 1991 date draws near.

[Moderator's Note: 909 and 917 are available, and I suppose 706, 903
and 905 will be also once they are no longer needed to hack our way to Mexico
from non-IDDD exchanges. But its a funny thing about 909: Telenet has used
that for their own administrative 'area code' for many years on their network
and I've a hunch Bellcore will take sympathy and make it the last one to
be put in service elsewhere. My guess is 917 will go, along with a couple
more of the XX0 codes first. By then, maybe 706, 903 and 905 will be open,
etc. I think 210 and 310 are also valid choices from Bellcore, no? Does
anyone remember when AT&T used to advertise their DDD service in its early
days by showing a telephone with the number 310-555-2368 on the dial? PT]edg@ames.arc.nasa.gov (Edward Greenberg) (09/24/89)

Other messages to telecom digest asked about 909 and 917; it had just been announced that 903 would be created in 1991(?) by splitting 214 in Texas. The reasons suggested for not using 909 and 917 were: 1. 909 looks too much like 707. 2. What is to be area 510 is next door to 916. (Telecom Moderator: You forgot about 903 coming into use in Texas; it was in the splits list I sent.)
