SATSUMA prefixes in area code 346

NANPA records 19 assigned NXX blocks to rate center SATSUMA in area code 346, 2.5% of the 752 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 NEW CINGULAR WIRELESS PCS, LLC - IL (5), ONVOY, LLC - TX (4), TELEPORT COMMUNICATIONS AMERICA, LLC - TX (3). The earliest assignment on record here is 2014-12-24 and the most recent 2026-07-21. 19 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 281, 832 – overlay codes cover the same geography, so a rate center is served by all of them.
