NWALTERBOR prefixes in area code 843

NANPA records 6 assigned NXX blocks to rate center NWALTERBOR in area code 843, 0.8% 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SC (3), PALMETTO RURAL TEL. COOP., INC. (2), SOUTH CAROLINA NET, INC. - SC (1). The earliest assignment on record here is 2001-11-05 and the most recent 2018-01-31. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
