SOUTH BEND prefixes in area code 574
NANPA records 113 assigned NXX blocks to rate center SOUTH BEND in area code 574, 28.0% of the 403 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. 27 holders hold those blocks, the largest being INDIANA BELL TEL CO INC (38), NEW CINGULAR WIRELESS PCS, LLC - IL (14), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (9). The earliest assignment on record here is 2001-03-06 and the most recent 2026-07-10. 71 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 360, 564 – overlay codes cover the same geography, so a rate center is served by all of them.
