SUMNER prefixes in area code 563
NANPA records 3 assigned NXX blocks to rate center SUMNER in area code 563, 0.8% of the 388 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. 2 holders hold those blocks, the largest being WINDSTREAM IOWA COMMUNICATIONS, INC. - SYSTEMS (2), MCC TELEPHONY LLC (1). The earliest assignment on record here is 2006-07-28 and the most recent 2015-10-30. 3 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 207, 253, 308, 618 – overlay codes cover the same geography, so a rate center is served by all of them.
