ENDICOTT prefixes in area code 607

NANPA records 24 assigned NXX blocks to rate center ENDICOTT in area code 607, 4.4% 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. 13 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (8), PAETEC ITEL, LLC (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NY (2). The earliest assignment on record here is 2001-05-15 and the most recent 2026-07-28. 21 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 code 509 – overlay codes cover the same geography, so a rate center is served by all of them.
