WEBB CITY prefixes in area code 417
NANPA records 6 assigned NXX blocks to rate center WEBB CITY in area code 417, 0.8% of the 711 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. 4 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MO (3), ONVOY, LLC - MO (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2003-06-26 and the most recent 2026-10-09. 5 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 918 – overlay codes cover the same geography, so a rate center is served by all of them.
