SAUGUS prefixes in area code 339

NANPA records 6 assigned NXX blocks to rate center SAUGUS in area code 339, 5.7% 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 ONVOY, LLC - MA (2), COMCAST IP PHONE, LLC (1), OMNIPOINT MIAMI E LICENSE, LLC (1). The earliest assignment on record here is 2001-03-20 and the most recent 2023-08-24. 6 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 617, 781 – overlay codes cover the same geography, so a rate center is served by all of them.
