WOBURN prefixes in area code 339

NANPA records 5 assigned NXX blocks to rate center WOBURN in area code 339, 4.8% of the 105 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MA (1), METROPCS, INC. (1), VERIZON NEW ENGLAND INC. (1). The earliest assignment on record here is 2001-03-19 and the most recent 2001-11-13. 5 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 781 – overlay codes cover the same geography, so a rate center is served by all of them.
