The 816 area code serves the Missouri side of the Kansas City metropolitan area and much of northwestern Missouri. One of the original area codes assigned in 1947, 816 covers Kansas City itself along with its eastern suburbs and the river city of St. Joseph to the north.
Quick Summary of the 816 Area Code

| Region | Kansas City Metropolitan Area |

Geographic Coverage
The 816 area code covers the Missouri portion of the Kansas City metro, including Kansas City, the eastern suburbs of Independence, Lee’s Summit, and Blue Springs, the Clay County cities of Liberty and Gladstone, and Raytown to the south. It extends north up the Missouri River to St. Joseph and shares its footprint with the newer 975 overlay.
Time Zone
The 816 area code observes Central Time (CT). Clocks follow Central Standard Time (UTC−6) in winter and shift to Central Daylight Time (UTC−5) from mid-March through early November. All of Missouri is on Central Time. From the West Coast, this region is two hours ahead of Pacific Time, so a 9:00 AM call in California reaches a 816 number at 11:00 AM local time.
Tip: Business hours across the 816 region generally run 9:00 AM to 5:00 PM Central Time, Monday through Friday.
How to Dial a 816 Number
Because area code 816 operates as part of an overlay, 10-digit dialing is mandatory for every local and long-distance call. You must dial the full 10-digit number (816 + the seven-digit line number) even when calling a neighbor across the street. For international callers, dial your country’s exit code, then +1 (the North American country code), then 816, followed by the seven-digit local number.
Scam Alerts for the 816 Area Code
Like every U.S. area code, 816 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Kansas City, Independence, Lee’s Summit, Blue Springs, St. Joseph, Liberty, Gladstone, Raytown should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Callers claiming you owe back taxes and threatening arrest unless you pay immediately. |
| Utility Shut-off | Fake Evergy reps demanding payment to avoid disconnection. |
| Bank Fraud Alerts | Robocalls impersonating your bank about “suspicious activity” to phish account details. |
| Grandparent Scam | A caller posing as a relative in trouble asking for emergency wire transfers. |
If you receive a suspicious call from a 816 number, take these steps to protect yourself:
- Do not share personal information such as Social Security numbers, bank details, or passwords over the phone.
- Hang up and verify by calling the organization back using an official number from its website.
- Report the call to the FTC at reportfraud.ftc.gov and to the Missouri Attorney General’s Office.
- Block the number and consider registering with the National Do Not Call Registry.
Red Flag: Legitimate agencies such as the IRS, Social Security Administration, or your local utility company (Ameren Missouri or Evergy) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 816 caller making such a demand is a scammer.
History and Economy of the 816 Region
n
Area code 816 is one of the original 86 codes established in 1947 and has served northwestern Missouri ever since; as the Kansas City metro grew, the 975 overlay was added in 2024 across the same territory. The regional economy is diverse and strategically important: Kansas City is a national logistics and rail hub, a center of the “Animal Health Corridor,” and home to major employers in aerospace, greeting cards (Hallmark), health-technology, and financial services, including a Federal Reserve Bank. The city is also famous for its barbecue and jazz heritage and its passionate support for the Chiefs and Royals, while St. Joseph adds animal-health manufacturing and food processing.
