Businesses across Tampa and surrounding cities use 813 numbers to project local presence and lift call answer rates.

History of the 813 area code

• 2022 656 added to serve the same region

Is the 813 area code safe? Spam and scam calls

813 is a legitimate geographic area code for Tampa — it is not a scam code or a premium-rate prefix, and a call from a 813 number is most likely a genuine local caller. The risk is not the area code itself but a tactic called neighbor spoofing: scammers fake their caller ID so an unwanted call appears to come from your own area code, because people answer familiar numbers more readily.

If you get an unexpected 813 call, a few signals point to a likely scam — a pre-recorded message, urgent pressure to act now, a demand for payment by gift card or wire transfer, or anyone asking for passwords, Social Security, or account numbers. Let suspicious calls go to voicemail, never share personal information, and report fraud to the FTC at reportfraud.ftc.gov.

The FCC consumer guide on spoofing explains your rights under the Truth in Caller ID Act. A real Tampa business will leave a clear voicemail and will not pressure you.

US carriers verify caller ID with the STIR/SHAKEN framework, which flags many spoofed numbers as "Spam Likely" before they ring. DialPhone 813 numbers are registered for STIR/SHAKEN attestation, so calls from your business are verified as genuine and reach customers without a false spam label. See the DialPhone guide to VoIP security for more.

Why get a 813 area code number for your business?

Getting a 813 number gives your business three measurable advantages over a toll-free or out-of-area number:

1. Local trust signal. Customers in Tampa recognize 813 as their home area code. Caller ID matching builds immediate credibility for service businesses, sales outreach, and patient communication.
2. Higher answer rate. Calls from a familiar local area code are answered far more often than unknown or toll-free numbers — industry measurements of local presence dialing put the lift at 20–40%, which matters most for outbound sales, appointment confirmations, and time-sensitive service callbacks.
3. Targeted marketing. Businesses serving Tampa and the broader Hillsborough County / Tampa can advertise a local number across print, radio, billboards, and digital channels for higher conversion than a national 800 number.

For businesses in Tampa and surrounding cities, top industries that benefit from local 813 presence include Hospitality, Real Estate, and Healthcare. DialPhone's AI receptionist is available for every 813 number — never miss a call, even after standard business hours.

What to know before getting a 813 number

• Number availability is finite. Popular Tampa area codes can be inventory-constrained — request specific vanity patterns early.
• Porting timing varies. Most 813 ports complete in 2-5 business days; complex multi-line legacy contracts can take 7-10.
• HIPAA tier required for healthcare. The Core $24 plan doesn't include a BAA — healthcare users need Advanced ($34) or above.
