Irvine, CA Area Code

Area code serving Irvine

Irvine sits in California, part of the West region and the Pacific Time zone. Its area code is 949, which covers southern and coastal Orange County including Irvine, Newport Beach and Mission Viejo. 949 has no overlay today, so every Irvine landline and mobile number with a local code starts with 949.

949 has served the area since 1998. If the region runs low on numbers, regulators will most likely add an overlay code on top rather than split the area, which would make 10-digit dialing mandatory.

Getting a Irvine phone number

Dialing in Irvine

Irvine is covered by the single area code 949 with no overlay, so some local calls may still connect with seven digits. Dialing all 10 digits (area code + seven-digit number) always works and is the safest habit. From outside the US, dial +1, then the area code and number.
