In response to a note I saw in TELECOM Digestregarding NPA-xxx-9901 in NYC, I tried 212-601-9901 and found it was the Kingbridge exchange with prefixes 601,543,548,549,796,884. I also tried, in response to same note, 212-578-9901 and got this list, not necessarily in this order: 578,689,779,545,889,220,251,447,469,458. (I located 578 as zone 1 in notes that were printed in 1976, and I see that 779,545,251,447, 469, and 458 replace what is now in area 718, judging from the zone numbers in those 1976 notes, which have 220 as zone 3, Bronx. That leaves 689 and 889 as the only other prefixes in this group in zone 1.)
