Regular Expression For US Phone Number in C#?

Question

Hello friends,

If you know regular expression for US phone validation please let me know. I have used

^[01]?[- .]?(\([2-9]\d{2}\)|[2-9]\d{2})[- .]?\d{3}[- .]?\d{4}$  expression . But it is fine for 10 digit numbers validation. I may have 12 digit numbers like 23-456-213-765  .  What is the regular expression for this?

Answer 1

You can edit the existing or add another one to validate the number. Each \d{3} \d{2} you see refers to the digits that are allowed to be inserted between the - or the . so all you have to do, is increase that number to allow more digits to be used.

@John: one word. traffic.

Sharon is just a spam bot who add vague words to replies and hope the hidden seo link added into the page's HTML source get undetected.

Please edit your quote to remove the hidden seo link from the word "might" added by the bot.
