LITTLEROCK prefixes in area code 501
NANPA records 252 assigned NXX blocks to rate center LITTLEROCK in area code 501, 39.9% 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. 34 holders hold those blocks, the largest being SOUTHWESTERN BELL (72), NEW CINGULAR WIRELESS PCS, LLC - IL (38), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (24). The earliest assignment on record here is 2001-02-26 and the most recent 2026-03-30. 153 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 712, 859 – overlay codes cover the same geography, so a rate center is served by all of them.
