Should you insert two zeros when dialing an international call?

Answer 1

In most cases, no. In most countries that begin telephone area codes with zero, the zero is actually a trunk prefix, not really part of the telephone number. Thus, for example:

• Dublin, Ireland: (01) becomes +353 1
• London, UK: (020) becomes +44 20
• Tokyo, Japan: (03) becomes +81 3
• Asunci

Answer 2

In most cases, no. In most countries that begin telephone area codes with zero, the zero is actually a trunk prefix, not really part of the telephone number. Thus, for example:

• Dublin, Ireland: (01) becomes +353 1
• London, UK: (020) becomes +44 20
• Tokyo, Japan: (03) becomes +81 3
• Asunción, Paraguay: (021) becomes +595 21

However, there are a few exceptions to this rule, most prominently Italy. All landline numbers in Italy begin with +39 0. For example, Rome (06) becomes +39 06, not +39 6.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)

Answer 3

Not necessarily. 00 is the prefix used from many countries for dialing international calls. However, many countries use other prefixes, such as 011 (USA, Canada, etc.), 010 (Japan), 0011 (Australia), 000 (Kenya), 009 (Nigeria), or 8~10 (Russia).

If you are calling on a GSM mobile phone, or most other mobile phones, your best bet is to enter the number in correct international format, beginning with the plus symbol and the telephone country code (one, two, or three digits, never beginning with zero). If you are calling from a landline phone, substitute the appropriate international dialing prefix (00 or other) applicable to the place from which you are calling. Also note that in some places there are multiple different prefixes, depending on which long distance telephone company you want to use, or for other specific purposes.
