BALDWIN prefixes in area code 336

NANPA records 5 assigned NXX blocks to rate center BALDWIN in area code 336, 0.6% 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. 3 holders hold those blocks, the largest being CAROLINA WEST WIRELESS, INC. (2), SKYLINE TEL. MEMBERSHIP CORP. (2), CHARTER IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2005-10-07 and the most recent 2017-12-20. 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 codes 231, 337, 563, 618 – overlay codes cover the same geography, so a rate center is served by all of them.
