MARSEILLES prefixes in area code 815

NANPA records 5 assigned NXX blocks to rate center MARSEILLES in area code 815, 0.6% of the 786 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. 3 holders hold those blocks, the largest being MARSEILLES TEL. CO. OF MARSEILLES (3), MCC TELEPHONY LLC (1), MTCO COMMUNICATIONS, INC. (1). The earliest assignment on record here is 2003-01-23 and the most recent 2008-05-13. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
