About area code 225

225 is one of 6 geographic area codes serving Louisiana; NANPA records its in-service date as August 17, 1998. It is not part of an overlay, so every number in its territory starts with 225. It is in the Central time zone. The places with the most assigned exchanges include Baton Rouge, Denham Springs, Gonzales, Plaquemine, and Donaldsonville. By population, its largest named places are Baton Rouge, Zachary, Gonzales, Denham Springs, and Donaldsonville.

How calls are dialed in 225

Carriers with 225 numbers

45 carriers hold the 501 central office codes assigned in 225. Bellsouth Telecomm INC d/b/a South Central Bell Tel has the most, with 132 (26%). 381 of the codes (76%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. The code holder is not necessarily the carrier serving a given number today, since numbers can be ported between providers.

Local calling areas in 225

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 225 has codes in 35 rate centers. Rate center names in the file are abbreviations; where one matches a Census place, the table links to that city's local-number page.
