ROXBORO prefixes in area code 336

NANPA records 13 assigned NXX blocks to rate center ROXBORO in area code 336, 1.7% 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. 7 holders hold those blocks, the largest being BRIGHTSPEED OF NORTH CAROLINA, LLC (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NC (2), FRONTIER COMMUNICATIONS OF AMERICA, INC. - NC (1). The earliest assignment on record here is 2002-05-16 and the most recent 2023-08-02. 9 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.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
