How to recognize scam

  • The caller says you’ve been selected to receive a grant for something from the government, but you need to pay a processing fee
  • The caller may say you’ve won a free vacation or some other prize, but there’s a shipping or handling fee, so they need your credit card information to send it to you
  • If you get a call from someone selling tickets to a big-prize lottery from another country
  • Caller trying to get you to buy something over the phone will offer a bonus or free gift if you purchase what they’re selling right away
  • If you miss a call from an unfamiliar number and it only rang once, don’t call back out of curiosity. It can redirects you to a pay-per-minute number that plays a fake recorded message
  • They offer to fix your computer
  • They’re collecting for a charity you’ve never heard of. Fake charities will insist on your credit card number.
  • They want your personal information
  • They are collecting a debt which you don’t remember incurring
  • They want you to invest in something
  • They want your credit card data

North American Numbering Plan

The North American Numbering Plan (NANP) is a telephone numbering plan that encompasses twenty-five distinct regions in twenty countries primarily in North America, including the Caribbean.

The NANP was originally devised in the 1940s by AT&T for the Bell System and independent telephone operators in North America to unify the diverse local numbering plans that had been established in the preceding decades.

The NANP divides the territories of its members into numbering plan areas (NPAs) which are encoded numerically with a three-digit telephone number prefix, commonly called the area code. The telephone number consists of a three-digit central office code and a four-digit station number. The combination of an area code and the telephone number serves as a destination routing address in the public switched telephone network.

Twenty-four countries and territories share the North American Numbering Plan (NANP), with a single country code. The formatting convention for phone numbers is NPA-NXX-XXXX, where NPA is the three digit area code and NXX-XXXX is the seven digit subscriber number.

Originally, local calls within an area code could be placed by dialing NXX-XXXX, omitting the area code, known as 7-digit dialing. Only calling a destination in a different area code required dialing the destination area code, known as ten-digit dialing, but due to the need for additional telephone numbers in many regions, seven digit dialing is becoming rare in the United States.
