SAG HARBOR prefixes in area code 631
NANPA records 6 assigned NXX blocks to rate center SAG HARBOR in area code 631, 0.8% 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 LEVEL 3 COMMUNICATIONS, LLC - NY (3), VERIZON NEW YORK, INC. (1), CENTURYLINK COMMUNICATIONS, LLC (1). 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
