BANCROFT prefixes in area code 515

NANPA records 3 assigned NXX blocks to rate center BANCROFT in area code 515, 0.5% of the 578 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 MCC TELEPHONY OF IOWA, LLC - IA (2), WINNEBAGO COOP. TEL. ASSN. - IA (1). The earliest assignment on record here is 2006-10-23 and the most recent 2010-04-16. 2 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 402, 989 – overlay codes cover the same geography, so a rate center is served by all of them.
