How to call from Country to Country

To make a direct international phone call from one country to another, you need to know the following things emphasized in bold:

The IDD (International Direct Dialing Number) for the country you are calling from.  This is available in the third column on the International Dialing Codes page.

For example, the IDD to call from the United States to another country is 011.  In the United Kingdom and in many other countries, the IDD is 00.  Other countries have different numbers, or may offer more than one depending on the carrier and type of service.  Make sure you have the correct IDD for the country you are calling from.  These will be the first numbers dialed, as shown below.

The Country Code of the country you are calling.  This is shown in the second column on the International Dialing Codes page.

    Every country has a distinct code, though in some cases it can be shared with other countries.  For example, The US, Canada, much of the Caribbean and even Guam use the country code of 1.  The Country code is dialed after the IDD and before the area code and phone number, as shown below.  

The city/area code (if any) for the number you are dialing.  Click the country's hyperlink on the International Dialing Codes page.

Some smaller countries don't use city/area codes, while larger ones may have hundreds of them.  Due to the tremendous growth most nations have experienced in telecommunications devices, codes are changed and added frequently.  If the name of the country on the International Dialing Codes page is highlighted as a hyperlink, there may be a list of city/area codes or other information that might help you complete your call.  This is the most difficult information on this site to keep up to date, so unfortunately some listings might be incomplete or outdated.  While some countries don't use city/area codes, if it is not listed here it may also mean that I don't have the code.

Example:  Calling from the United Kingdom to Rio de Janeiro, Brazil.

How to use the International Dialing Codes page.

1.  Look up the IDD for the UK  >> 2.  Look up the Country Code for Brazil. >> 3. Look up the Area Code for Rio -- click the "Brazil" link >>

4. Dial the phone number you are calling.

Dialing sequence:

00 + 55 + 21 + XXX-XXXX

NOTE: In most hotels, you will need to dial 9, 0 or perhaps another number to obtain an outside line.

The sequence is essentially the same when dialing from anywhere, to anywhere.
