TERRABELLA prefixes in area code 559
NANPA records 5 assigned NXX blocks to rate center TERRABELLA in area code 559, 0.6% 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. 4 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - CA (2), LEVEL 3 COMMUNICATIONS, LLC - CA (1), PACIFIC BELL (1). The earliest assignment on record here is 2025-04-11 and the most recent 2025-04-11. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
