MCKINNEY prefixes in area code 945

NANPA records 24 assigned NXX blocks to rate center MCKINNEY in area code 945, 8.0% of the 300 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. 11 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (4), ONVOY, LLC - TX (4). The earliest assignment on record here is 2020-11-19 and the most recent 2026-06-25. 24 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 codes 214, 469, 972 – overlay codes cover the same geography, so a rate center is served by all of them.
