PLANO prefixes in area code 945
NANPA records 26 assigned NXX blocks to rate center PLANO in area code 945, 8.7% 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. 9 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (8), ONVOY, LLC - TX (6), ONVOY SPECTRUM, LLC (3). The earliest assignment on record here is 2020-11-19 and the most recent 2026-10-20. 26 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, 331, 469, 630 – overlay codes cover the same geography, so a rate center is served by all of them.
