[comp.dcom.telecom] Details on new area code 510

mcb@ncis.tis.llnl.gov (Michael C. Berch) (06/07/89)

The press release from Pacific Bell, quoted in the San Francisco
Chronicle, gives the phase-in dates for the new NPA 510.  (By the way,
is this the first "real" [i.e., geographical] N10 NPA?)

Inception is scheduled for 7 October 1991, with a four-month grace
period when NPA 415 will still work for the affected numbers.  Final
cutover is scheduled for 27 January 1992.

NPA 510 will encompass Alameda and Contra Costa counties, which
currently have 842,388 customers out of the current 2,005,687
customers in NPA 415.
