Area Code Lookup. Enter city, state, or country name to receive the Country code and area code (STD). International names use the English spelling and do not use State. Eg. Delhi will return the Delhi cities in the world. Burlington Canada will return the Burlington cities in Canada. Burlington ON will return the Burlington cities in Ontario Canada. State or Province Name will return all the codes in the state(Only USA and Canada). Country name will return the Country code (ISD).
Reverse code lookup. Enter the area code (North America) and get the cities for that area code. For International reverse lookups prefix the country code with a plus sign, and put dashes between the country and city code (i.e. +49 will display "Germany"; +49-30 will display "Berlin, Germany"). You may need to drop leading zeros on country code information.
