NANPA records 3 assigned NXX blocks to rate center NEW GLARUS in area code 608, 0.4% of the 785 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 MT. VERNON TEL. CO. (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (1), ONVOY, LLC - WI (1). The earliest assignment on record here is 2003-11-21 and the most recent 2021-07-15. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
