History of Area Code 936
Area code 936 was created in 2000 as a split from area code 409. Before this change, all of these regions were part of 409, which served much of southeastern Texas, including the Beaumont and Galveston areas.
Due to population growth and increased demand for phone numbers, a new area code was needed. That’s when 936 was introduced to ensure enough numbers were available for residents and businesses. Since its creation, 936 has remained the only area code serving the Deep East Texas region, with no further splits or overlays.
Time Zone of Area Code 936
Area code 936 follows the Central Time Zone (CT), which is the same time zone used across most of Texas. This includes:
- Central Standard Time (CST)
- Central Daylight Time (CDT) during daylight saving
This is important for businesses and individuals who communicate with people in different states.
