SOUTHOLD prefixes in area code 631
NANPA records 4 assigned NXX blocks to rate center SOUTHOLD in area code 631, 0.5% of the 782 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. 4 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - NY (1), VERIZON NEW YORK, INC. (1), LEVEL 3 COMMUNICATIONS, LLC - NY (1). The earliest assignment on record here is 2004-08-17 and the most recent 2015-07-16. 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 934 – overlay codes cover the same geography, so a rate center is served by all of them.
