You can call from Belarus directly to practically any country of the world. For international calls you have
to dial "8", then wait for the tone, then dial "10" + code of the country you are calling to
+ area code + phone number.
Calls to the numbers within Belarus are made using
different procedures, depending from what type of phone you are calling - landline or mobile.
If you are calling from a Belarusian cell phone: Just dial a 7-digit phone number both for landline and
If you are calling from a landline phone: To call to another landline phone within the same area code
you only dial a 7-digit number. To call to a Belarusian mobile phone you have to dial 8, then wait for the tone,
then dial 029, and only then the 7-digit phone number.
For your information:
Area code for mobile phones is 029 (if dialed from abroad zero is omitted). Most mobile numbers in Belarus
start with 6, 7 or 4 (and then other 6 digits).
