NANPA records 5 assigned NXX blocks to rate center WH CASTLE in area code 225, 1.0% of the 501 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. 4 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - GA (2), CENTURYLINK COMMUNICATIONS, LLC (1), TELEPORT COMMUNICATIONS AMERICA LA - LLC (1). The earliest assignment on record here is 2014-05-21 and the most recent 2023-01-09. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
