Hi all,

I'm trying to fill out an online form and need to fill in my phone number (US format I presume).

It didn't work, so I looked at its validation code. It's a regex and the code is:

^[0-9]{5-15}$

Here it is again, now put in context:

HTML

What can I fill in so that I can move past this form? (Only numbes are accepted, leaving it blank doesn't work either.)

Thanks!

Petter

What I have tried:

I have tried numerous variants at regexlib.com but can't find something that works. Things I've tried: blank, 1, 111111111, (301)-123-1234

Hope it help.
Here is a link to RegEx documentation:

This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx:

Solution 1

It's not a valid regex for a telephone number: what it matches is literally a single numeric digit followed by the text "{5-15}" and nothing else.

What they probably meant to say was:

C#

^[0-9]{5,15}$

Which matches "any string of numeric digits between 5 and 15 characters long, inclusive."

To be honest, if that's the quality of their regex testing, I wouldn't give any personal information to them, and definitely nothing that contained a credit card number.

Thanks a lot. Didn't recall that a comma was necessary. Actually I used this form to get in touch with the patenting department at Google. Guess they don't want new ideas from outside the company. :)
