IIRC I had a list of countries each of which had the relevant international dialling code recorded. The user of a form would select their country and enter a telephone number. The international dialling code would be added if not present or validated if '+' was present. Any leading 0 (after an int. code) would be removed. Beyond that I think all you can do is validate that a certain number of digits must have been entered as different people/countries use different formatting chars: space , . - : etc etc Another approach would be to request each component separately: int.code, area code, local number. This of course was all done within a function/class not a single statement. HTH Graham
