OXFORD prefixes in area code 508

NANPA records 4 assigned NXX blocks to rate center OXFORD in area code 508, 0.5% 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. 3 holders hold those blocks, the largest being PAETEC ITEL, LLC (2), CHARTER IP ENABLED SERVICES, LLC (1), VERIZON NEW ENGLAND INC. (1). The earliest assignment on record here is 2003-06-19 and the most recent 2004-05-04. 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 codes 207, 248, 283, 308 – overlay codes cover the same geography, so a rate center is served by all of them.
