About 813 Area Code
Area code 813 serves Tampa and the broader Tampa Bay region in west-central Florida. Introduced in 1953 as Florida's second area code, 813 covers major population centers including Tampa, Brandon, Riverview and Plant City, extending across Hillsborough County, most of central and southeastern Pasco County, and Oldsmar in Pinellas County. The code supports local voice and SMS-capable numbers used by businesses, healthcare providers, financial services firms and tech companies across one of Florida's most dynamic metropolitan areas.
The 813 region drives a diversified economy mixing finance (Raymond James, major banks), healthcare (Tampa General Hospital, Moffitt Cancer Center), technology startups, defense contractors serving MacDill Air Force Base, and tourism. Local businesses use 813 numbers for customer support, appointment scheduling, sales calls and logistics coordination. A local number matches customer expectations and yields higher answer rates than toll-free or out-of-state alternatives because it signals a genuine Tampa Bay connection.
FoneSwift lists live 813 inventory and capabilities on this page. Search numbers to see which ones support Voice, SMS and MMS. Area code availability varies over time. If a local 813 number is not immediately available, the overlay code 656 serves the same geographic area and delivers identical local presence. Nearby codes like 727 (St. Petersburg, Clearwater) may also fit businesses serving the broader Tampa Bay metro.
If your business targets Tampa or the Tampa Bay region, publish numbers in both local and E.164 formats (e.g., (813) 555-1234 and +1 813 555 1234) and register messaging traffic if you plan A2P campaigns. For porting, see our porting guide. Keeping the same number preserves customer familiarity and avoids friction when you switch providers. The 813 area code remains a strong identifier of Tampa despite the 656 overlay, making it valuable for brand recognition and local marketing.

Quick Facts about 813 Area Code
Interesting tidbits about this area code 813
Florida's second area code
Area code 813 was created in 1953 when Florida split the original 305 code, making 813 the second area code in the state and one of the earliest in the southeastern United States.
Wall Street of the South
Tampa is often called the Wall Street of the South due to its concentration of financial services firms. Nearly one in four business and information services firms in Florida call the 813 region home.
813 Day celebration
Tampa celebrates 813 Day every August 13 (8/13), honoring the area code that has become synonymous with local identity and pride. Businesses and residents post photos using #813Day.
Overlay with 656
In 2022, area code 656 was introduced as an overlay to 813 due to number exhaustion. Both codes now serve the same geographic area, requiring 10-digit dialing for all calls.
Oldsmar exception
Oldsmar, located in Pinellas County, kept the 813 code despite being geographically in 727 territory. This preserved connectivity with Tampa-based alarm systems and internet dial-up services.
Historic pulse dialing advantage
When rotary phones were common, 813 required only 12 pulses to dial (compared to an average of 19 for area codes created around the same time), reflecting Tampa's priority as a growing regional hub.

How Does Local 813 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 813 number in Tampa and Florida, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.
The typical parts of a United States local number are:
- Country code (+1): identifies United States for international routing.
- Area code (813): directs the call to the Tampa / Florida region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
Example formats:
| International Format (E.164) | +1 813 555 1234 |
| Local Format (National) | (813) 555-1234 |
