Let’s get straight to the point: The 756 area code is not a valid, assigned area code within the United States or the broader North American Numbering Plan (NANP).
Understanding Unassigned Area Codes
The NANP, which governs phone numbers in the U.S., Canada, and parts of the Caribbean, has a pool of possible three-digit combinations. While hundreds are assigned to specific geographic regions, many others, like the 756 area code, remain officially “unassigned.” This means that no legitimate phone calls originating from a U.S. city or state will begin with these three digits as their area code.

If It’s Not a US Area Code, What Is It?
While the 756 area code is unassigned in North America, the number sequence is used elsewhere in the world. It is sometimes associated with international locations like Botswana or parts of China as a regional code. This is a critical distinction, as calls from these locations are international and can be very expensive to call back.
More importantly for U.S. residents, however, is that this number is frequently used in scams precisely because it is not a recognizable U.S. area code.
Why You Might See a Call from a 756 Area Code
Even though the 756 area code isn’t officially in use in the U.S., it can still appear on your phone. This is almost always due to deceptive practices used by scammers.
Caller ID Spoofing
The most common reason to see a call from an unassigned area code is through a practice called “spoofing.” Scammers use technology to falsify the number that appears on your caller ID. They can make it seem like they are calling from any number they choose, including fake or unassigned ones like the 756 area code. They do this to hide their true location and to arouse your curiosity, making it more likely that you’ll answer.
The “One-Ring” International Scam
A frequent scam involving non-U.S. numbers is the “one-ring” or “Wangiri” scam. Here’s how it works:
- Scammers call your number and hang up after just one ring, ensuring you can’t answer.
- You see a missed call from an unfamiliar number, like one appearing to be from the 756 area code.
- Curious, you call the number back.
- The number is a premium-rate international line, and you are immediately charged high per-minute rates for the call, with the scammers getting a cut of the fees.
What to Do If You Get a Call from a 756 Area Code
Given that the 756 area code is not assigned in the U.S., the best course of action is to treat any call from it with extreme caution.
- Do Not Answer: If you don’t recognize the number, let the call go to voicemail. A legitimate caller will leave a message.
- Never Call Back: This is the most important rule. Calling back confirms your number is active and could connect you to a premium-rate international line, costing you money.
- Do Not Provide Personal Information: If you do answer by mistake, never give out any personal or financial information. Hang up immediately.
- Block the Number: Use your smartphone’s built-in feature to block the number to prevent further calls.
- Report It: You can report scam calls to the Federal Communications Commission (FCC) and the Federal Trade Commission (FTC).
In conclusion, your search for the location of the 756 area code ends here—it is not in use in the United States. Think of it as an immediate red flag for a potential scam. By being an informed and cautious phone user, you can easily protect yourself from fraudulent calls.
