Section: Codes in Range 1000-2999 - Geographic Numbers
02392 is not an area code in its own right. The area code is in fact 023, and the following 2 digits are part of the local number.
So 02392 should actually be written 023 92, although it makes no difference when dialling the number.
For information on the formatting of 023 numbers, see the page for the 023 area code.
