History of the 816 area code

The 816 area code was one of the original 86 area codes assigned in 1947 when the North American Numbering Plan was first deployed. As Kansas City grew and number demand increased, overlay code 975 was added to serve the same geographic region — a common solution that avoids forcing existing subscribers to change their numbers.

• 1947 816 entered service (one of the 86 original NANP area codes)
• 2023 975 added to serve the same region

Is the 816 area code safe? Spam and scam calls

816 is a legitimate geographic area code for Kansas City — it is not a scam code or a premium-rate prefix, and a call from a 816 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 816 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 Kansas City 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 816 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 816 area code number for your business?

Getting a 816 number gives your business three measurable advantages over a toll-free or out-of-area number:

1. Local trust signal. Customers in Kansas City recognize 816 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 Kansas City and the broader Kansas City Metro (Missouri side) can advertise a local number across print, radio, billboards, and digital channels for higher conversion than a national 800 number.

For businesses in Kansas City and surrounding cities, top industries that benefit from local 816 presence include Professional Services, Healthcare, and Retail. DialPhone's AI receptionist is available for every 816 number — never miss a call, even after standard business hours.
