NDLDPTNCHS prefixes in area code 409

NANPA records 26 assigned NXX blocks to rate center NDLDPTNCHS in area code 409, 6.0% of the 434 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. 9 holders hold those blocks, the largest being SOUTHWESTERN BELL (13), NEW CINGULAR WIRELESS PCS, LLC - IL (6), TELEPORT COMMUNICATIONS AMERICA, LLC - TX (1). The earliest assignment on record here is 2001-02-08 and the most recent 2025-01-29. 21 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
