409 Area Code Guide for Southeast Texas

The 409 area code serves part of Southeast Texas. It covers cities along the Gulf Coast and near the Louisiana state line. If you see a 409 number, the call is usually coming from places like Beaumont, Port Arthur, Orange, or Galveston. This guide explains where the 409 area code is used, how it began, and how to dial it the right way.

For residents and businesses, the 409 area code is more than a set of digits. It connects ports, refineries, beach towns, and Piney Woods communities. Knowing a little about this area code can help you plan calls, build a local presence, and spot possible scams.

What Is the 409 Area Code and How Does It Work?

The 409 area code is a telephone area code in the North American Numbering Plan. It identifies phone numbers assigned to a specific region, in this case a large stretch of Southeast Texas. When you dial a number with area code 409, you are reaching someone in that region unless the number has been moved to a nationwide service.

Area code 409 is not a toll-free or premium rate code. It is a standard geographic code. The typical way to write a number is (409) XXX‑XXXX or 409‑XXX‑XXXX. Charges for calling a 409 number depend on your phone plan, just like any other U.S. number.

Where Is Area Code 409 Located in Southeast Texas?

The 409 area code covers much of Southeast Texas, including the Golden Triangle (Beaumont, Port Arthur, and Orange), the Gulf Coast around Galveston, and several East Texas communities. It includes industrial hubs, ports, and coastal towns.

Major cities and communities

• Beaumont
• Port Arthur
• Orange
• Nederland, Groves, and Port Neches
• Vidor and Bridge City
• Lumberton, Silsbee, and Kountze

Neighboring area codes include 281/346/713 around the Houston metro (covering parts of northern Galveston County), 936 to the north, 979 to the west, and 337 just across the Louisiana border. Exact boundaries can split counties and even cities, so some nearby communities use a different code.

A Brief History of Area Code 409 in Texas

Area code 409 was created in the early 1980s after a split from 713, the original code for much of Southeast Texas. The change made room for rapid growth around Houston and the upper Gulf Coast, and it gave the Golden Triangle and Galveston their own numbering space.

Later splits: 936 and 979

As the region continued to grow, 409 was reduced in size. In the late 1990s, the 936 area code was introduced for many inland communities to the north and northeast, including Conroe, Huntsville, Lufkin, and Nacogdoches.

In 2000, the 979 area code was created to serve the Brazos Valley and parts of the coastal plain, including Bryan, College Station, Lake Jackson, and Bay City. After these changes, the 409 area code focused on the Golden Triangle, Galveston, and nearby Gulf Coast towns.

Area code 409 does not currently have an overlay, so new numbers within its boundaries still use 409.

How to Dial Numbers in the 409 Area Code Correctly

Dialing a 409 number is straightforward. Many carriers now require 10‑digit dialing for local calls. For long‑distance calls within the U.S., you often dial 1 first. From outside the country, include +1 before the area code.

• Inside the U.S. and Canada: 1 + 409 + seven‑digit number
• From outside the U.S.: your exit code + 1 + 409 + seven‑digit number (for example, +1 409 XXX XXXX)
• Text messages use the same format as calls

Many regions moved to 10‑digit dialing after the nationwide adoption of 988 as a three‑digit code for mental health support. If in doubt, use 10 digits when calling a 409 number.

Central Time Zone and Daylight Saving for 409 Calls

The 409 area code follows Central Time. It observes Central Standard Time (CST) in fall and winter and Central Daylight Time (CDT) in spring and summer. This helps callers schedule across time zones and avoid missed calls.

Business and Lifestyle Across the 409 Region of Texas

The Golden Triangle—anchored by Beaumont, Port Arthur, and Orange—is a major center for petrochemical refining, logistics, and shipbuilding. The ports of Beaumont and Port Arthur handle heavy cargo, and Texas City is a key refining hub. Farther south, Galveston Island draws visitors for beaches, fishing, cruises, and historic districts. The University of Texas Medical Branch (UTMB) in Galveston is also a major employer.

Inland communities in Jasper, Newton, and Tyler counties sit in the Piney Woods and support forestry, timber, and outdoor recreation. Because the 409 area code is on the Gulf Coast, hurricanes and tropical storms can affect service. Many businesses keep backup contact plans and battery power to stay connected during weather events.

Getting a 409 Number for Personal or Business Use

You can get a 409 number through a mobile carrier, a local landline provider, or a VoIP service. A local number helps businesses signal a Southeast Texas presence and can build trust with customers in the area.

Number portability rules let you keep your 409 area code when you change carriers. If you move out of the region, you can often keep the same number with mobile or VoIP service. Traditional landline moves may have limits based on location and rate centers. The 409 area code is not toll‑free, so any charges depend on your specific phone plan.
