HAYMARKET prefixes in area code 571

NANPA records 13 assigned NXX blocks to rate center HAYMARKET in area code 571, 2.0% 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. 7 holders hold those blocks, the largest being VERIZON SOUTH, INC. - VA (CONTEL) (3), LEVEL 3 COMMUNICATIONS, LLC - VA (2), BANDWIDTH.COM CLEC, LLC - VA (2). The earliest assignment on record here is 2001-05-23 and the most recent 2026-04-24. 13 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 703 – overlay codes cover the same geography, so a rate center is served by all of them.
