LINDL SWAN prefixes in area code 430

NANPA records 4 assigned NXX blocks to rate center LINDL SWAN in area code 430, 1.4% of the 289 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. 3 holders hold those blocks, the largest being ONVOY, LLC - TX (2), AT&T ENTERPRISES, LLC (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2011-09-23 and the most recent 2024-03-14. 4 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 903 – overlay codes cover the same geography, so a rate center is served by all of them.
