TRUCKEE prefixes in area code 530

NANPA records 13 assigned NXX blocks to rate center TRUCKEE in area code 530, 1.7% of the 782 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. 9 holders hold those blocks, the largest being PACIFIC BELL (4), T-MOBILE USA, INC. (2), IP HORIZON LLC (1). The earliest assignment on record here is 2002-02-21 and the most recent 2023-08-10. 10 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 837 – overlay codes cover the same geography, so a rate center is served by all of them.
