LXTNPKGRML prefixes in area code 301

NANPA records 11 assigned NXX blocks to rate center LXTNPKGRML in area code 301, 1.4% of the 784 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 VERIZON MARYLAND, INC. (9), OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (1), LEVEL 3 COMMUNICATIONS, LLC - MD (1). 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 240 – overlay codes cover the same geography, so a rate center is served by all of them.
