FERNDALE prefixes in area code 501
NANPA records 7 assigned NXX blocks to rate center FERNDALE in area code 501, 1.1% of the 631 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 WINDSTREAM COMMUNICATIONS, INC. - AR (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1), LEVEL 3 TELECOM OF ARKANSAS, LLC - AR (1). The earliest assignment on record here is 2001-07-05 and the most recent 2025-03-13. 6 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 369, 484, 610, 707 – overlay codes cover the same geography, so a rate center is served by all of them.
