W BLOCTON prefixes in area code 205

NANPA records 5 assigned NXX blocks to rate center W BLOCTON in area code 205, 0.6% of the 785 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. 5 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - AL (1), PAETEC ITEL, LLC (1), ONVOY, LLC - AL (1). The earliest assignment on record here is 2016-02-17 and the most recent 2019-10-02. 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 659 – overlay codes cover the same geography, so a rate center is served by all of them.
