813 Area Code: The Complete Guide to Tampa Bay Phone Numbers

Ask anyone in Tampa what number says "local," and the answer is instant: 813. It has identified the city and its suburbs for decades.

But the region has quietly changed. A second code now shares the same map, and the old habit of dialing seven digits no longer works.

This guide covers what the 813 area code actually serves, the cities and county behind it, the 656 overlay that joined it, the dialing rules in force today, and how a local number helps a business compete across Tampa Bay.

• 813 has identified Tampa Bay businesses for over seven decades — since 1953, the 813 area code has been the recognized caller ID for Hillsborough County, making it one of Florida's most established and regionally trusted three-digit identifiers for local businesses and residents alike
• The 656 overlay joined 813 in February 2022 without disrupting existing numbers — regulators chose an overlay over a geographic split, meaning every existing 813 number remained unchanged while new lines began drawing from the 656 pool across the same Hillsborough County footprint
• Ten-digit dialing is now mandatory for every call in the Tampa Bay region — since the 656 overlay took effect, all local calls require the full area code plus seven-digit number, even between neighbors on the same street in Brandon or Temple Terrace

WHERE THE 813 AREA CODE COVERS

The code is tightly tied to one Florida county. Unlike sprawling multi-county codes, 813 has a compact, well-defined footprint.

It sits in the Eastern Time Zone and observes daylight saving time.

The Geographic Footprint

The numbering plan area includes:

Major Cities to Know

Tampa is the population center and economic engine — a hub for finance, healthcare, shipping, and tourism. Its suburbs carry most of the region's growth.

Key communities inside the code include Brandon, Riverview, Plant City, Temple Terrace, and parts of Zephyrhills and Wesley Chapel. Together they make this one of Florida's busiest metro numbering areas.

A SHORT HISTORY OF THE CODE

The 813 code dates back to 1953, when it covered a much larger swath of central and southwest Florida. Over the years, growth forced repeated splits.

Codes like 941 and 727 were carved out of the original 813 territory. Each split trimmed the map until 813 settled into roughly the Hillsborough County region it serves today.

• 813 originally covered a vast stretch of central and southwest Florida when it launched in 1953 — its original footprint extended well beyond Tampa to include what are now the Sarasota, Fort Myers, and St. Petersburg metro areas, making it one of Florida's most geographically expansive original codes
• The 941 split in 1995 carved out Sarasota and southwest Florida from the 813 territory — rapid population growth across Sarasota, Manatee, and Charlotte counties drove the split, reducing 813's footprint significantly and marking Tampa's emergence as a standalone metro code
• The 727 split in 1998 removed the St. Petersburg and Clearwater area from 813 — Pinellas County's dense population and the explosive growth of the St. Pete-Clearwater market exhausted available numbers, pushing regulators to create 727 and shrink 813 to roughly the Hillsborough County region it serves today

THE 656 OVERLAY: WHAT HAPPENED AND WHEN

Even the trimmed-down 813 eventually ran out of available number prefixes. Regulators chose an overlay rather than another split.

How the 656 Overlay Works

An overlay adds a second code (656) over the same geographic region. No existing 813 number changed. New lines simply began drawing from the 656 pool.

The Real Timeline

Here is the part many older guides get muddled:

656 only activates a number once 813's available prefixes are assigned, so 813 numbers are still issued — supply is simply shared now.

HOW TO DIAL IN TAMPA BAY TODAY

Because two codes share one map, 10-digit dialing is mandatory. A seven-digit local call no longer connects.

The Simple Rule

Always include the area code, even for a call across the street.

Why It Matters for Phone Systems

Business PBXs, alarm panels, and auto-dialers programmed for seven-digit dialing may fail. If yours have not been updated, reprogram them for the full 10-digit format.

WHY AN 813 NUMBER STILL MATTERS FOR BUSINESS

A local code is a trust signal. Tampa Bay customers answer calls from familiar codes far more often than unknown or toll-free numbers.

For a roofer in Brandon or a medical office in Temple Terrace, an 813 number quietly says "we are part of this community."

Local Presence Without a Local Office

You no longer need a physical Tampa office to hold an 813 number. A cloud phone line rings on any device, anywhere.

That lets a business serve Tampa Bay while operating remotely or across several markets. My Country Mobile (MCM) provisions local numbers and routes calls over its global voice network, so an 813 line stays clear and reliable wherever your team sits.

Fast Setup as You Grow

If you manage presence across multiple regions, our overview of business phone numbers shows how teams handle several local codes at once.

COMMON MISTAKES TO AVOID

A few simple oversights create friction in overlay regions like Tampa Bay.

Printing Seven-Digit Numbers

Signage, business cards, and vehicle wraps showing only seven digits now confuse callers. Update every public number to the full 10-digit format.

Assuming 656 Is Out of Area

A 656 number is not a different city or distant region. It serves the exact same Hillsborough County footprint as 813 and carries the same local value.

Ignoring Spoofing Risk

Scammers spoof familiar local codes so calls look trustworthy. Be cautious with unexpected calls demanding payment or personal data, even when the code looks local.
