BONHAM prefixes in area code 903

NANPA records 10 assigned NXX blocks to rate center BONHAM in area code 903, 1.3% of the 771 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. 6 holders hold those blocks, the largest being FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (3), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2002-08-05 and the most recent 2023-08-16. 9 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 code 430 – overlay codes cover the same geography, so a rate center is served by all of them.
