GLENSFALLS prefixes in area code 518

NANPA records 45 assigned NXX blocks to rate center GLENSFALLS in area code 518, 5.8% of the 775 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. 19 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (11), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NY (7), PAETEC ITEL, LLC (5). The earliest assignment on record here is 2001-07-10 and the most recent 2024-07-30. 32 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 838 – overlay codes cover the same geography, so a rate center is served by all of them.
