BELLEVILLE prefixes in area code 730
NANPA records 12 assigned NXX blocks to rate center BELLEVILLE in area code 730, 9.2% of the 130 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. 1 holder holds those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - IL (12). The earliest assignment on record here is 2025-03-24 and the most recent 2025-04-14. 12 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 223, 315, 353, 479 – overlay codes cover the same geography, so a rate center is served by all of them.
