GONZALES prefixes in area code 225

NANPA records 18 assigned NXX blocks to rate center GONZALES in area code 225, 3.6% of the 501 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. 9 holders hold those blocks, the largest being EAST ASCENSION TELEPHONE COMPANY, LLC (5), VOICESTREAM GSM I, LLC (3), NEW CINGULAR WIRELESS PCS, LLC - GA (3). The earliest assignment on record here is 2001-03-14 and the most recent 2026-06-12. 13 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 830, 831 – overlay codes cover the same geography, so a rate center is served by all of them.
