HERNDON prefixes in area code 571
NANPA records 74 assigned NXX blocks to rate center HERNDON in area code 571, 11.6% of the 639 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. 16 holders hold those blocks, the largest being OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (18), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - VA (13), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (12). The earliest assignment on record here is 2001-03-22 and the most recent 2026-08-20. 70 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 703, 785 – overlay codes cover the same geography, so a rate center is served by all of them.
