ELWOOD prefixes in area code 765

NANPA records 6 assigned NXX blocks to rate center ELWOOD in area code 765, 0.8% of the 725 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 INDIANA BELL TEL CO INC (2), CENTURYLINK COMMUNICATIONS, LLC (1), LEVEL 3 TELECOM OF INDIANA, LP - IN (1). The earliest assignment on record here is 2014-06-13 and the most recent 2026-07-30. 5 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 308, 779, 815, 913 – overlay codes cover the same geography, so a rate center is served by all of them.
