MANTECA prefixes in area code 209
NANPA records 44 assigned NXX blocks to rate center MANTECA in area code 209, 5.6% 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. 15 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (19), FRONTIER CALIFORNIA INC. (5), T-MOBILE USA, INC. (4). The earliest assignment on record here is 2002-02-21 and the most recent 2025-01-28. 29 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.
