NATICK prefixes in area code 508

NANPA records 26 assigned NXX blocks to rate center NATICK in area code 508, 3.5% 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. 12 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (7), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (4), PAETEC ITEL, LLC (3). The earliest assignment on record here is 2018-02-15 and the most recent 2018-02-15. 18 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.
