The 330 area code is a landmark of Northeast Ohio, a digital handshake that connects numerous towns and cities. This guide provides a comprehensive look at the 330 area code, including its origins, the areas it covers, and the time zone it observes.
Geographic Coverage and Key Locations
The 330 area code covers a wide swath of northeast Ohio, including a diverse range of cities and communities. If you live or do business in this part of the state, it’s important to be aware of the area code’s geographic reach.
The 330 area code is located in the Eastern Time Zone (ET), which means that it observes Eastern Standard Time (EST) during standard time and Eastern Daylight Time (EDT) when daylight saving time is in effect.
Time Zone Information and Daylight Saving Time
If you’re calling a 330 area code, remember that you’ll be calling someone in the Eastern Time zone.
During Daylight Saving Time (DST), the time zone is UTC/GMT -4:00 hours.
In 2025, Daylight Saving Time starts on March 9th at 2:00 AM and ends on November 2nd at 2:00 AM (EDT).
History and Evolution of the 330 Area Code
The 330 area code came into being in the mid-1990s because it was predicted that the original 216 area code would soon run out of phone numbers. Before the change, Akron’s area code was 216.
Switching to the 330 area code meant that many phones, fax machines, and computer modems had to be reprogrammed. The changeover to area code 330 was phased in gradually.
Later, a new area code, 234, was introduced and overlaid on top of 330. So, if you’re calling someone in northeast Ohio, chances are good that their area code is either 330 or 234.
330 Day
People in the 330 area celebrate “330 Day” every year on March 30th. It’s a way to show pride in the region and acknowledge how important the area code is to the community.
In Closing
The 330 area code does more than connect phone calls. It represents a specific part of Northeast Ohio and the people and businesses that call it home.
