Where is telephone country code 001203?

Answer 1

That depends on what part of the number in your question 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.), area code 209 (Stockton and Modesto, California).

However, if your international access prefix is 001, then you're asking about telephone country code +20, which is Egypt. Numbers beginning with +20 9 are in the southern part of Egypt.

To avoid the confusion of different access prefixes used around the world, it is best to quote an international telephone number beginning with a single plus symbol and the correct telephone country code, omitting any dialing prefix.

(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.)
