CATOCTIN prefixes in area code 540
NANPA records 4 assigned NXX blocks to rate center CATOCTIN in area code 540, 0.5% of the 786 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 VERIZON VIRGINIA, INC. (3), LEVEL 3 COMMUNICATIONS, LLC - VA (1). The earliest assignment on record here is 2003-03-26 and the most recent 2003-03-26. 4 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 826 – overlay codes cover the same geography, so a rate center is served by all of them.
