DURHAM prefixes in area code 919
NANPA records 155 assigned NXX blocks to rate center DURHAM in area code 919, 19.8% of the 781 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. 13 holders hold those blocks, the largest being FRONTIER COMMUNICATIONS OF THE CAROLINAS INC. - NC (82), SUNCOM DBA T-MOBILE USA (14), PAETEC ITEL, LLC (13). The earliest assignment on record here is 2001-02-13 and the most recent 2023-05-18. 77 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 codes 573, 603, 620, 984 – overlay codes cover the same geography, so a rate center is served by all of them.
