EASTPORT prefixes in area code 631
NANPA records 7 assigned NXX blocks to rate center EASTPORT in area code 631, 0.9% 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. 5 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - NY (3), VERIZON NEW YORK, INC. (1), TC SYSTEMS, INC. - NY (1). 6 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 codes 207, 231 – overlay codes cover the same geography, so a rate center is served by all of them.
