SUMNER prefixes in area code 253

NANPA records 15 assigned NXX blocks to rate center SUMNER in area code 253, 3.0% of the 508 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. 8 holders hold those blocks, the largest being QWEST CORPORATION (4), ONVOY, LLC - WA (3), NEW CINGULAR WIRELESS PCS, LLC (2). The earliest assignment on record here is 2001-04-23 and the most recent 2023-01-10. 10 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 207, 308, 563, 618 – 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.
