CADIZ prefixes in area code 270

NANPA records 9 assigned NXX blocks to rate center CADIZ in area code 270, 1.2% of the 769 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 - KY (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - KY (2), TELEPORT COMMUNICATIONS AMERICA, LLC - KY (1). The earliest assignment on record here is 2001-11-15 and the most recent 2022-01-25. 6 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 code 740 – overlay codes cover the same geography, so a rate center is served by all of them.
