LEONARDTN prefixes in area code 240
NANPA records 17 assigned NXX blocks to rate center LEONARDTN in area code 240, 2.2% 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. 8 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MD (10), CORE COMMUNICATIONS, INC.- MD (1), TELEPORT COMMUNICATIONS AMERICA, LLC - DC (1). The earliest assignment on record here is 2001-02-13 and the most recent 2023-01-09. 15 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 227, 301 – overlay codes cover the same geography, so a rate center is served by all of them.
