GARDENCITY prefixes in area code 620

NANPA records 18 assigned NXX blocks to rate center GARDENCITY in area code 620, 2.6% of the 705 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. 6 holders hold those blocks, the largest being SOUTHWESTERN BELL (8), NEW CINGULAR WIRELESS PCS, LLC - IL (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - KS (2). The earliest assignment on record here is 2002-05-09 and the most recent 2026-01-07. 11 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 432, 435, 507, 515 – overlay codes cover the same geography, so a rate center is served by all of them.
