NO ATTLEBO prefixes in area code 508

NANPA records 6 assigned NXX blocks to rate center NO ATTLEBO in area code 508, 0.8% of the 749 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 VERIZON NEW ENGLAND INC. (3), COMCAST IP PHONE, LLC (1), LEVEL 3 COMMUNICATIONS, LLC - MA (1). 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 774 – overlay codes cover the same geography, so a rate center is served by all of them.
