FRONTROYAL prefixes in area code 540

NANPA records 12 assigned NXX blocks to rate center FRONTROYAL in area code 540, 1.5% 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. 5 holders hold those blocks, the largest being BRIGHTSPEED OF VIRGINIA, LLC (5), OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - VA (2). The earliest assignment on record here is 2001-06-13 and the most recent 2021-10-08. 10 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 826 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
