PARKVILLE prefixes in area code 410

NANPA records 14 assigned NXX blocks to rate center PARKVILLE in area code 410, 1.8% of the 783 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. 4 holders hold those blocks, the largest being VERIZON MARYLAND, INC. (10), COMCAST IP PHONE, LLC (2), TELEPORT COMMUNICATIONS AMERICA, LLC - MD (1). The earliest assignment on record here is 2005-02-10 and the most recent 2005-02-10. 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 codes 443, 667 – overlay codes cover the same geography, so a rate center is served by all of them.
