CULBERTSON prefixes in area code 406
NANPA records 3 assigned NXX blocks to rate center CULBERTSON in area code 406, 0.4% of the 754 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. 2 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (2), NEMONT TEL COOP INC (1). The earliest assignment on record here is 2010-10-20 and the most recent 2010-10-20. 3 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 308 – overlay codes cover the same geography, so a rate center is served by all of them.
