HAYDEN prefixes in area code 520
NANPA records 10 assigned NXX blocks to rate center HAYDEN in area code 520, 1.4% of the 699 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 ONVOY, LLC - AZ (3), QWEST CORPORATION (3), IP HORIZON LLC (2). The earliest assignment on record here is 2002-10-24 and the most recent 2026-10-30. 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 970 – overlay codes cover the same geography, so a rate center is served by all of them.
