GLENSFALLS prefixes in area code 838

NANPA records 4 assigned NXX blocks to rate center GLENSFALLS in area code 838, 1.8% of the 227 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. 2 holders hold those blocks, the largest being ONVOY, LLC- NY (3), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2021-01-07 and the most recent 2026-07-28. 4 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 518 – overlay codes cover the same geography, so a rate center is served by all of them.
