0203 area code
Section: Codes in Range 1000-2999 - Geographic Numbers
0203 is not an area code in its own right. The area code is in fact 020, and the following digit is part of the local number.
So 0203 should actually be written 020 3, although it makes no difference when dialling the number.
For information on the formatting of 020 numbers, see the page for the 020 area code.
