WARSAW prefixes in area code 574
NANPA records 13 assigned NXX blocks to rate center WARSAW in area code 574, 3.2% 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. 5 holders hold those blocks, the largest being BRIGHTSPEED OF INDIANA, LLC (6), T-MOBILE USA, INC. (2), ONVOY, LLC - IN (2). The earliest assignment on record here is 2001-03-30 and the most recent 2024-03-13. 9 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 217, 472, 585, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
