FRANKLIN prefixes in area code 615

NANPA records 36 assigned NXX blocks to rate center FRANKLIN in area code 615, 4.6% 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. 11 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (11), PAETEC ITEL, LLC (6), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - TN (6). The earliest assignment on record here is 2001-08-23 and the most recent 2024-02-19. 25 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 207, 217, 270, 304 – overlay codes cover the same geography, so a rate center is served by all of them.
