MERCED prefixes in area code 209

NANPA records 57 assigned NXX blocks to rate center MERCED in area code 209, 7.3% of the 784 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. 16 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (17), PACIFIC BELL (15), T-MOBILE USA, INC. (5). The earliest assignment on record here is 2001-06-26 and the most recent 2022-04-11. 41 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 code 350 – 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.
