PARSONS prefixes in area code 731

NANPA records 5 assigned NXX blocks to rate center PARSONS in area code 731, 1.3% of the 395 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. 3 holders hold those blocks, the largest being TENNESSEE TEL. CO. (3), CHARTER IP ENABLED SERVICES, LLC (1), NEW CINGULAR WIRELESS PCS, LLC - GA (1). The earliest assignment on record here is 2003-04-30 and the most recent 2013-05-29. 3 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 304, 620, 681 – overlay codes cover the same geography, so a rate center is served by all of them.
