SOUTHPORT prefixes in area code 910

NANPA records 10 assigned NXX blocks to rate center SOUTHPORT in area code 910, 1.3% of the 785 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. 6 holders hold those blocks, the largest being SUNCOM DBA T-MOBILE USA (3), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NC (2). The earliest assignment on record here is 2001-06-25 and the most recent 2022-01-20. 8 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 472 – 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.
