Regular Area Codes

Region codes were created to manage only that issue. If you partition your country into regions, each with its different code, then, at that point, you can rehash phone numbers again and again and over once more.

Therefore, the North American Numbering System (NANS) was created by the United States and U.S. regions, Canada, Bermuda, and 16 Caribbean nations, including the Bahamas, Jamaica, Barbados, Trinidad, and Tobago have same area code like 866 area code and 800 area code . The NANS framework is comprised of 3-digit region codes in addition to 7-digit phone numbers. If you call a 7-digit number inside your region code, you don't have to incorporate the region code by using theinfotrunk.
