LANDENBERG prefixes in area code 484

NANPA records 4 assigned NXX blocks to rate center LANDENBERG in area code 484, 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. 3 holders hold those blocks, the largest being PAETEC ITEL, LLC (2), ONVOY, LLC - PA (1), CORE COMMUNICATIONS, INC. - PA (1). 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 code 610 – overlay codes cover the same geography, so a rate center is served by all of them.
