MEDFORD prefixes in area code 781
NANPA records 24 assigned NXX blocks to rate center MEDFORD in area code 781, 3.1% of the 769 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. 9 holders hold those blocks, the largest being MCIMETRO ACCESS TRANSMISSION SERVICES LLC (6), VERIZON NEW ENGLAND INC. (6), PAETEC ITEL, LLC (3). The earliest assignment on record here is 2001-02-23 and the most recent 2024-12-18. 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 codes 339, 458, 541, 580 – overlay codes cover the same geography, so a rate center is served by all of them.
