HAGERSTOWN prefixes in area code 240

NANPA records 33 assigned NXX blocks to rate center HAGERSTOWN in area code 240, 4.2% 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. 20 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - MD (6), OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (5), VERIZON MARYLAND, INC. (3). The earliest assignment on record here is 2001-04-16 and the most recent 2023-02-10. 32 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, 765 – overlay codes cover the same geography, so a rate center is served by all of them.
