ROWLEY prefixes in area code 978

NANPA records 4 assigned NXX blocks to rate center ROWLEY in area code 978, 0.5% of the 773 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. 4 holders hold those blocks, the largest being COMCAST IP PHONE, LLC (1), PEERLESS NETWORK OF MASSACHUSETTS, LLC - MA (1), LEVEL 3 COMMUNICATIONS, LLC - MA (1). The earliest assignment on record here is 2001-12-31 and the most recent 2001-12-31. 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 319, 351 – overlay codes cover the same geography, so a rate center is served by all of them.
