ST JOHN prefixes in area code 219

NANPA records 8 assigned NXX blocks to rate center ST JOHN in area code 219, 1.6% of the 495 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 ONVOY, LLC - IN (3), INDIANA BELL TEL CO INC (2), FRACTEL, LLC (1). The earliest assignment on record here is 2002-04-10 and the most recent 2025-03-13. 7 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 509, 620 – overlay codes cover the same geography, so a rate center is served by all of them.
