Tampa's metro area is home to nearly 3 million residents — and the 813 area code is the prefix connecting businesses to most of that population. West Central Florida has seen consistent growth across healthcare, finance, logistics, and tourism, making Hillsborough County one of the Southeast's most competitive commercial environments. Whether you are tracing a call, targeting Tampa customers, or evaluating a local phone number for your business, this guide covers the geography, history, overlay rules, and how to secure a Tampa prefix without setting foot in Florida.
What Is the 813 Area Code?
The 813 area code is the primary telephone prefix for West Central Florida, serving Hillsborough County and portions of Pasco County. Established in 1953, it is one of the Southeast's oldest and most recognized prefixes, having served the Tampa Bay region through decades of population and economic growth.
In 2022, the 656 area code was introduced as an overlay, meaning both codes now serve the same geographic region. Calls placed from either prefix reach the same communities — there is no service or geographic distinction between the two codes.
Hillsborough County forms the core of the coverage zone. The county is home to the Port of Tampa Bay — one of the largest ports in the Southeast by cargo tonnage — MacDill Air Force Base, and the University of South Florida, giving the region a diverse economic base that drives consistent demand for reliable local business communication.
Cities the 813 Area Code Serves
The 813 area code blankets a wide cross-section of West Central Florida, from Tampa's urban core outward through the county's expanding suburban ring. Key cities and communities within the service area include:
- Tampa — Florida's third-largest city; center of the region's finance, healthcare, and port economy
- Brandon — one of Hillsborough's largest and most commercially active suburban communities
- Plant City — known for winter strawberry production and a growing industrial base
- Temple Terrace — home to the University of South Florida's main campus
- Riverview — a rapidly expanding residential suburb southeast of Tampa
- Valrico — an established suburban community in eastern Hillsborough County
- Lutz — a residential area straddling Hillsborough and Pasco counties
- Town 'n' Country — a densely populated census-designated area west of Tampa
- Sun City Center — one of Florida's largest active-adult retirement communities
- Carrollwood — an upscale suburban community north of Tampa
Together, these communities represent a wide range of demographics and industries — from Tampa's downtown finance and medical districts to the manufacturing and distribution operations concentrated east of the city.
History of the 813 Area Code
The 813 area code launched on January 1, 1953, as a split from Florida's original 305 prefix, which had covered the entire state. At that time, the original area code 813 territory stretched from Pasco County in the north all the way to Collier County in the southwest, covering a vast stretch of Florida's Gulf Coast.
Population growth in subsequent decades forced two major geographic splits:
- 1995: The southwestern corridor — including Sarasota, Fort Myers, and Naples — was reassigned to the 941 area code.
- 1998: Pinellas County (St. Petersburg and Clearwater) was separated and given the 727 area code.
These divisions reduced the 813 footprint to its current Hillsborough-centered territory. When the region next faced number exhaustion, regulators chose an overlay rather than another geographic split: the 656 area code was activated on February 22, 2022, adding a new pool of numbers without displacing any existing subscribers.
813 Area Code Time Zone and the 656 Overlay
All phone numbers in this region — whether carrying the 813 area code prefix or the newer 656 overlay — operate on Eastern Time (ET). That means Eastern Standard Time (EST, UTC-5) during winter months and Eastern Daylight Time (EDT, UTC-4) from spring through autumn.
Since the 656 overlay launched in 2022, mandatory 10-digit dialing applies to all calls within the service area. Every local call must include the full area code before the seven-digit number — seven-digit dialing no longer connects, regardless of whether you are calling an 813 or 656 number.
For businesses scheduling calls with Tampa-area contacts from other time zones, a 9:00 a.m. Tampa meeting is 6:00 a.m. Pacific and 2:00 p.m. in London. Knowing the dialing protocol and time zone for area code 813 prevents scheduling errors and missed connections for distributed teams operating across regions.
Why Tampa Businesses Choose the 813 Area Code
When customers see a familiar local prefix on an incoming call, answer rates climb. A 813 area code number tells Tampa residents they are dealing with a business that is present in their community — or at least committed to it. That local signal carries through to website listings, Google Business profiles, and any marketing touchpoint where a phone number appears.
For companies outside Florida, a Tampa number enables local market entry without the cost of a physical office. Remote sales teams, contact centers, and regional service businesses can all route calls through a local prefix from anywhere, projecting a consistent Tampa presence to inbound customers.
This advantage holds across major markets. Businesses expanding into cities like Houston have found the same dynamic with a 281 area code, and companies targeting Atlanta see the same pattern with a 678 area code — local numbers consistently outperform toll-free lines in markets where community connection influences buying behavior.

How to Get a Local Tampa Phone Number
Getting a local Tampa number is a fast, fully remote process. Virtual phone providers allow businesses to register a 813 area code number without signing carrier contracts, purchasing hardware, or establishing any physical presence in Florida.
The typical steps:
- Select a provider — Choose a VoIP service with access to Florida numbers in the Hillsborough County region.
- Choose your number — Browse available numbers; many providers include vanity options for easy-recall combinations.
- Configure call routing — Direct the number to your existing mobile phone, desktop softphone, or cloud PBX system.
- Activate — Numbers typically go live within minutes, not business days.
Number portability rules allow businesses that already hold a Tampa number from another carrier to transfer it without changing the digits, preserving continuity with existing contacts.
