SMITHVILLE prefixes in area code 615

NANPA records 16 assigned NXX blocks to rate center SMITHVILLE in area code 615, 2.0% 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. 2 holders hold those blocks, the largest being DEKALB TEL. COOP. (13), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TN (3). The earliest assignment on record here is 2010-03-18 and the most recent 2013-07-29. 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 codes 229, 234, 304, 330 – overlay codes cover the same geography, so a rate center is served by all of them.
