Verified Nov 1, 2026 · Source: NANPA CO Code Assignment Records
FRESNO prefixes in area code 559
NANPA records 264 assigned NXX blocks to rate center FRESNO in area code 559, 33.6% of the 785 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. 36 holders hold those blocks, the largest being PACIFIC BELL (86), NEW CINGULAR WIRELESS PCS, LLC (45), T-MOBILE USA, INC. (21). The earliest assignment on record here is 2001-08-22 and the most recent 2026-09-18. 181 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 209, 357 – overlay codes cover the same geography, so a rate center is served by all of them.
