WALTHAM prefixes in area code 781
NANPA records 72 assigned NXX blocks to rate center WALTHAM in area code 781, 9.4% 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. 14 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (28), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (9), TC SYSTEMS, INC. (6). The earliest assignment on record here is 2001-02-22 and the most recent 2021-10-22. 46 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, 617 – overlay codes cover the same geography, so a rate center is served by all of them.
