Where is telephone country code plus 0011668?

Answer 1

Telephone country codes never begin with zero.

If your international access prefix is 00, then you're asking about telephone country code +1 (North America = USA, Canada, etc.), area code 666 (unused).

If your international access prefix is 001, then you're asking about telephone country code +66 (Thailand), and a number beginning with 6 (probably a VoIP number in Thailand).

Because of the ambiguity of different places using different access prefixes, it is much less confusing to quote international telephone numbers beginning with the actual country code, including the plus symbol.

(The plus signmeans "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

Country codes never begin with zero. The number shown above is a country code with a location-dependent international access prefix on the front and the beginning of a national number on the end.

If your international access prefix is 00 (the most commonly used prefix), then you're looking at country code +1, which is North America (USA, Canada, etc.), but with an invalid domestic number. The North American area code can never begin with 1.

If your international access prefix is 001, then you're again looking at country code +1, but this time with area code 668, which is potentially valid, but currently unused.

If your international access prefix is 0011, then you're in Australia, looking at country code +66, which is Thailand, with a national number beginning with 8, which is a mobile phone.

Conclusion: you are in Australia, trying to call a mobile in Thailand, country code +66, national number beginning with 8.

To avoid the confusion regarding international access prefixes and such things, always quote an international telephone number beginning with the plus sign and the country code, omitting the access prefix.
