DOBSON prefixes in area code 336
NANPA records 4 assigned NXX blocks to rate center DOBSON in area code 336, 0.5% of the 783 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 PIEDMONT COMMUNICATIONS SERVICES, INC. - NC (1), BRIGHTSPEED OF NORTH CAROLINA, LLC (1), LEVEL 3 COMMUNICATIONS, LLC - NC (1). The earliest assignment on record here is 2003-10-21 and the most recent 2020-05-12. 2 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 743 – overlay codes cover the same geography, so a rate center is served by all of them.
