TheRence UK Telephone Number Validation
Hi,
I am trying to write a validation formula that will allow two format types for UK phone numbers, these are;
01234 567890 and 0123 456 7890.
Whilst I can write a validation rule for one format type;
NOT(REGEX(Phone, "\\d{4}( \\d{3})( \\d{4})")).
I cannot seem to write a rule that will allow for two. I had tried;
OR(NOT(REGEX(Phone, "\\d{4}( \\d{3})( \\d{4})")), NOT(REGEX(Phone, "\\d{5}( \\d{6})")))
But this does not work. Any advice to what I am hoping is a simple answer would be grateful.
This one should work:
AND( NOT(REGEX(Phone, "\\d{4}( \\d{3})( \\d{4})")), NOT(REGEX(Phone, "\\d{5}( \\d{6})")) )

There are very many more formats than just those two. Additionally, your second format isn't valid for the actual number range used in your example.
UK telephone numbers begin with the 0 trunk code or the +44 country code. One of these is placed before the area code and that is followed by a space and finally the subscriber number.
Not all UK numbers have 10 digits. Some have 9 or in a few rare cases, only 7 digits.
The area code can have between 2 and 5 digits. The subscriber number has between 4 and 8 digits.

Valid formats for geographic numbers include 2+8, 3+7, 4+6, 4+5, 5+5 and 5+4 (and 0+10 for NDO** numbers).
Non-geographic numbers mostly use 0+10 format, but some 0800 numbers and all 0500 numbers use 0+9 format.
There's also one 0800 number and one 0845 number using 0+7 format.

Hii I am trying thsi javascript validation for Uk numbers validation with space in numbers where i am wrong ?
if (document.forms[0].phone.value == "")
{alert("You did not enter your Phone No.Please provide it.");
document.forms[0].phone.focus();return false;
}
var input=0;
input=document.forms[0].phone.value;
re = ^0\d{2,4}[ -]{1}[\d]{3}[\d -]{1}[\d -]{1}[\d]{1,4}$;
if(re.test(input) == false) {
alert('Phone number can contain only digits');
document.forms[0].phone.focus();
return false;
} else if(input.length < 11) {
alert('Phone number must be greater then 10 digits');
return false;
}
