Waco, TX Area Code

Area code serving Waco

Waco sits in Texas, part of the South region and the Central Time zone. Its area code is 254, which covers central Texas including Killeen, Waco, Temple and surrounding counties. 254 has no overlay today, so every Waco landline and mobile number with a local code starts with 254.

254 has served the area since 1997. 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 Waco phone number

Any new landline, mobile or VoIP number from a local carrier in Waco gets the 254 area code. Numbers come from the blocks each carrier holds in the area; a number ported in from elsewhere keeps its original area code, so you may also see out-of-state codes locally.

Dialing in Waco

Waco is covered by the single area code 254 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.
