PORTAGE prefixes in area code 219

NANPA records 22 assigned NXX blocks to rate center PORTAGE in area code 219, 4.4% 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. 10 holders hold those blocks, the largest being FRONTIER NORTH, INC.. - IN (6), NEW CINGULAR WIRELESS PCS, LLC - IL (4), METROPCS, INC. (3). The earliest assignment on record here is 2007-02-28 and the most recent 2024-09-09. 16 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 419, 435, 582, 608 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
