Trying to validate two different format in one regular expression

Question

I want to validate these formats in one regular expression in asp.net:

XX-XXXXXXX or XXX-XX-XXXX

These have to be numeric only no characters except the "-".

Is this possible? I've been trying without any success so I want to ask the experts.

Thanks, Pune

Try something like this:

/^([0-9]{2}-[0-9]{7}|[0-9]{2}-[0-9]{2}-[0-9]{4})$/

Thanks Jaumzera but that didn't work... – Puneo Jul 20 '17 at 14:43
I didn't realize that you said about X being numbers. – Jaumzera Jul 20 '17 at 16:30
I updated the regex and the link as well. – Jaumzera Jul 20 '17 at 16:31
Awesome thank you!! – Puneo Jul 20 '17 at 17:20
This actually doesn't work correctly as it will say the value "00-00-00-0000" matches. See https://dotnetfiddle.net/r2VcdB. – Craig W. Jul 20 '17 at 17:34
You've got the reason. Of course it must be put between ^ and $. – Jaumzera Jul 20 '17 at 17:46

The following should work given your requirements.

"(^\d{2}-\d{7}$)|(^\d{3}-\d{2}-\d{4}$)"
