CARTERLAKE prefixes in area code 712
NANPA records 5 assigned NXX blocks to rate center CARTERLAKE in area code 712, 0.8% 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. 5 holders hold those blocks, the largest being ONVOY, LLC - IA (1), PAETEC ITEL, LLC (1), QWEST CORPORATION (1). The earliest assignment on record here is 2001-04-03 and the most recent 2026-06-16. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
