SEGUIN prefixes in area code 830
NANPA records 24 assigned NXX blocks to rate center SEGUIN in area code 830, 4.8% of the 496 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. 14 holders hold those blocks, the largest being SOUTHWESTERN BELL (7), NEW CINGULAR WIRELESS PCS, LLC - IL (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (2). The earliest assignment on record here is 2001-05-11 and the most recent 2022-11-07. 19 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
