There are a couple of easy ways 1. Client-side There is a nice ASP.net AJAX control in the toolkit which offers this if you want to use it. Link - http://ajax.asp.net/ajaxtoolkit/MaskedEdit/MaskedEdit.aspx[^] 2. Regular expression validator You could write a simple regular expression to match the input against and use a validator on the page. The regular expression would be something like ^d{4}-\d{3}-\d{3}$ (Not 100% sure of the exact syntax) Try www.regexlib.com as a great source for help and examples of regular expressions.

Here is your code for Validation of Phone Number, with asp:regularexpressionvalidator <%@ Page Language=VB Debug=true %> Validating a Phone Number with a RegularExpressionValidator Control
Please enter your phone number:
You must enter a phone number in the form of 9999-999-999.Regards, Satips.:rose:

Thanks, but if the first number should be either 3 or 4 so how should we give? like 0000-000-000 or 000-000-000
The first digit is only three. Like wise you have to mention. (999) 999-9999.

Not Both at a time go with any one. Mostly the standard format is (999) 999-9999. like this only. The first three numbers inside braces denotes the Code and the other seven numbers will represents the other. Everywhere you see only 10 didgit phone number only.
