Where is country code 00120?

Answer 1

Telephone country codes never begin with a zero. The location of the number you are asking about depends on what part of the number is your international access prefix.

If your international access prefix is 00 (the most commonly used), then you're asking about telephone country code +1 (North America = USA, Canada, etc.), and an area code beginning with 20 (need one more digit to narrow down the location).

If your international access prefix is 001, then you're asking about telephone country code +20, which is Egypt.

To avoid the confusion of different prefixes used around the world, it is best to quote an international telephone number beginning with a single plus symbol and the telephone country code. For example, +20 for Egypt.

(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 2

It looks like you have quoted a telephone code beginning with an international dialing prefix. However, since different countries use different prefixes, that makes it impossible to tell what you're asking about.

If your international prefix is 00 (the most commonly used), then you're asking about telephone country code +1, which is North America (USA, Canada, etc.), and area code 020, which does not exist. There are no valid telephone numbers beginning with +1 0 or +1 1.

If your international prefix is 001, then you're asking about telephone country code +020, which does not exist. Telephone country codes never begin with zero.
