📍 Geographic Location of Alabama
Geographic Coverage and Jurisdiction
Area code 334 is a geographic North American Numbering Plan (NANP) code serving the southeastern portion of the U.S. state of Alabama. Administratively, it falls under the Alabama Public Service Commission. The numbering plan area (NPA) 334 encompasses the state's capital, Montgomery, as well as the cities of Dothan, Auburn, Opelika, and Phenix City. It also covers the Alabama counties of Autauga, Barbour, Bullock, Butler, Chambers, Coffee, Covington, Crenshaw, Dale, Elmore, Geneva, Henry, Houston, Lee, Lowndes, Macon, Montgomery, Pike, Russell, and Tallapoosa. This region includes major universities, such as Auburn University, and significant military installations like Maxwell Air Force Base.
Dialing Formats and Procedures
Within the 334 area, local calls are placed using the standard 10-digit dialing format (NPA-NXX-XXXX), which is mandatory across all of Alabama. For callers from within the United States or Canada, the international format is: +1 334 XXX XXXX. When dialing from abroad, you must replace the leading '1' with the international access code of your country (e.g., 011 from most of North America, 00 from many European countries). For example, to call a landline in Montgomery from the UK, you would dial: 00 1 334 123 4567.
Overlay and Number Exhaustion
Area code 334 was created in 1997 as a split from area code 205, which originally covered the entire state. To address number exhaustion, an overlay area code, 938, was introduced in 2023. This means that new telephone numbers in the same geographic region may be assigned either 334 or 938. Consequently, 10-digit dialing is required for all local calls, even between numbers with the same area code. The overlay does not change the cost or routing of calls; it simply expands the available number pool.
Caller Instructions
For local callers within the 334/938 overlay region, simply dial the 10-digit number (area code + 7-digit number). For long-distance calls within the United States, dial 1 followed by the 10-digit number. International callers should use the country code for the United States (+1) and omit any leading trunk prefix. Always verify the correct number of digits: a complete international number will have 11 digits after the '+' sign (e.g., +1 334 555 0123).
