SOUTHINGTN prefixes in area code 959

NANPA records 4 assigned NXX blocks to rate center SOUTHINGTN in area code 959, 2.4% of the 164 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 - CT (2), BANDWIDTH.COM CLEC, LLC - CT (1), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2020-06-30 and the most recent 2026-05-18. 4 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 860 – overlay codes cover the same geography, so a rate center is served by all of them.
