DAYTON prefixes in area code 937
NANPA records 251 assigned NXX blocks to rate center DAYTON in area code 937, 32.1% of the 781 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. 31 holders hold those blocks, the largest being OHIO BELL TEL CO (81), T-MOBILE USA, INC. (34), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (32). The earliest assignment on record here is 2001-01-24 and the most recent 2022-07-21. 133 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 326, 423, 503, 509 – overlay codes cover the same geography, so a rate center is served by all of them.
