Dialling international calling number by country, all exit codes or international codes and area numbers in national telephone calls (or area code) and telephone codes for calls abroad.
Telephone codes or area codes to know how to call other countries: 1st international area codes, 2nd country code and 3rd the area code. In other words, the exit prefix of the origin of the call, then the destination and finally the region, territory or province of the country where we call.
Normally for Europe and most countries this international area code is 00, with someEXCEPTIONS, see above link (International exit prefixes).
If the call is made from the United States (US) or Canada, the exit code is 011 and if it is from Australia, 0011.
-CALLS TO LANDLINES:
(Exit code of the country you are calling from) (Destination country code) (Area code) (Landline numbers)
Example, call from Acapulco (Mexico) to El Paso Texas (US): 00 1 915 xxx xxxx
Where 00 is the Mexico exit code, 1 the Texas (US) code, 915 the El Paso area code and xxx xxxx the landline number.
Example, call from El Paso Texas (US) to Acapulco (Mexico): 011 52 744 xxx xxxx
Where 011 is the Texas exit code, 52 the Mexico country code, 744 the Acapulco area code and xxx xxxx the landline number.
-CALLS TO CELL PHONES:
– Countries that are part of the North American Numbering Plan(NANP) such as Canada, the US and its Territories (Guam, Northern Mariana Islands, US Virgin Islands, Puerto Rico and American Samoa) plus some Caribbean countries (Anguilla, Antigua and Barbuda, Bahamas, Barbados, Bermuda, Dominica, Grenada, Cayman Islands, Turks and Caicos Islands, British Virgin Islands, Jamaica, Montserrat, Dominican Republic, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Sint Maarten and Trinidad and Tobago) include the area code in the cell phone number:
(Exit code of the country you are calling from) (Destination country code) (Area code) (Cell phone numbers)
Example, if you call a cell phone in El Paso (Texas) from Mexico, it would be the same as the structure of the landlines, explained above, 00 1 915 xxx xxxx.
-For the rest of the countries the call structure would be:
(Exit code from where you are calling) (Destination country code) (Cell phone numbers)
Example if you call a cell phone in Spain from Mexico it would be: 00 34 6xx xxx xxx or 00 34 7xx xxx xxx
Where 00 is the exit code for Mexico, 34 the code for Spain and 6xx xxx xxx or 7xx xxx xxx the cell phone number.
# NATIONAL CALLS:
In this case, neither the exit code or the country code are marked, but only the area code that identifies each zone, region, territory or province of the country in which we are making the call, so that the structure of call would be:
-CALLS TO LANDLINES:
(Area code) (Landline numbers)
Keep in mind that some countries also use a code between cities.
-CALLS TO CELL PHONES:
In the case of the countries that are part of the North American Numbering Plan (Canada, US with its territories plus some Caribbean countries):
(Area code) (Cell phone numbers)
For the rest of the countries, the number in question is dialed, taking into account that some use that code between cities as happens in calls to national landlines:
