KILLEEN prefixes in area code 254
NANPA records 91 assigned NXX blocks to rate center KILLEEN in area code 254, 13.5% of the 672 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. 15 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (31), BRIGHTSPEED OF TEXAS, INC. (20), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (12). The earliest assignment on record here is 2001-01-15 and the most recent 2026-10-29. 62 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
