WALSENBURG prefixes in area code 719

NANPA records 7 assigned NXX blocks to rate center WALSENBURG in area code 719, 1.1% of the 665 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. 5 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - CO (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CO (2), BANDWIDTH.COM CLEC, LLC - CO (1). The earliest assignment on record here is 2002-10-10 and the most recent 2022-11-15. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
