This can be done if you can precisely define a valid phone number for your
purpose.

Does it include area code?
Can it include international codes?

Update this post with your criteria.

Hi all,
i would like to make a phone book in excel a data validation
constraint i want is in some rows to insert numbers only no text
allowed, and at the same time i want those numbers to be treated as
text to prohibit their calculation, i tried to format as text but then
text will be accepted , i tried data validation with the is number
function, but this wouldn't prohibit the calculation , i need a mix of
those two, to stop the user entering text and in the meanwhile treat
numbers entered as text.

yes indeed it must have the ability of entering area codes and
international codes like (+1) or (+30)
i want the user to be able to enter any number , the + sign of course
or the "00"(when she enters 00 , the 0's must show up)
Thanks

a valid number is like :
+306934778585
or
+9613209845
