Where is telephone country code 001206397?

Answer 1

That depends on the international access prefix from the location you're calling from, which is why it is less confusing to quote international telephone numbers without the prefix.

'00' is the most commonly used international access prefix, leaving you with a question about +1 206 397, which is a telephone prefix for Seattle, Washington, USA. (Telephone country code +1 is North America, including USA and Canada. Area code 206 is Seattle plus a few suburbs. The 397 prefix is specifically in Seattle, used by a combination of landline and cellphone numbers.)

Alternatively, some places use '001' as the international access prefix, leaving you with a question about +20 63 97, which is an invalid number in Egypt (telephone country code +20). +20 62 is the telephone area code for Suez, and +20 64 is Ismalia, but +20 63 is not currently in use as a telephone area code.

(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.)
