NO HOPKINS prefixes in area code 712

NANPA records 3 assigned NXX blocks to rate center NO HOPKINS in area code 712, 0.5% of the 633 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 EMBARQ MISSOURI, INC. DBA CENTURYLINK - MO (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1), LEVEL 3 COMMUNICATIONS, LLC - IA (1). The earliest assignment on record here is 2013-10-01 and the most recent 2021-07-21. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
