GLNCNYONCY prefixes in area code 435

NANPA records 4 assigned NXX blocks to rate center GLNCNYONCY in area code 435, 0.8% of the 501 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. 3 holders hold those blocks, the largest being ONVOY, LLC - UT (2), PEERLESS NETWORK OF UTAH, LLC - UT (1), QWEST CORPORATION (1). The earliest assignment on record here is 2007-10-18 and the most recent 2021-04-26. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
