Where is telephone country code 203?

Answer 1

Telephone country code +20 (dialed as 00 20or 011 20 from many places) is Egypt, and telephone area code +20 3 is Alexandria, Egypt.

There are also many places where a national number might begin with 203; for example, +1 203 is in Connecticut, USA, and +44 20 3 is a number in London, UK (country code +44, city code 20, local number beginning with 3).

(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.)
Country code +20 is Egypt, and a number beginning with +20 3 is a landline in Alexandria.

Answer 2

The 00 at the beginning is not part of the telephone code, it is a commonly used international access prefix. Country code +1 is North America (USA, Canada, etc.), and area code +1 203 is southwestern Connecticut, USA.

Alternatively, if your international access prefix is 001 instead of 00, then you're asking about country code +20 (Egypt), area code +20 3 (Alexandria).

To avoid this sort of confusion, it is best to always write international telephone numbers in proper international format, beginning with a single plus sign and the telephone country code, omitting any location-dependent dialing prefixes.
