ITHACA prefixes in area code 607

NANPA records 40 assigned NXX blocks to rate center ITHACA in area code 607, 7.3% of the 548 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 12 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (11), PAETEC ITEL, LLC (7), TC SYSTEMS, INC. - NY (6). The earliest assignment on record here is 2001-08-15 and the most recent 2009-07-30. 29 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 353, 402, 608, 989 – overlay codes cover the same geography, so a rate center is served by all of them.
