AUBURN prefixes in area code 508

NANPA records 12 assigned NXX blocks to rate center AUBURN in area code 508, 1.6% 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. 5 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - MA (4), AMERICAN MESSAGING SERVICES, LLC (3), VERIZON NEW ENGLAND INC. (3). 2 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 217, 253, 260, 270 – overlay codes cover the same geography, so a rate center is served by all of them.
