Regular expression for digits

I need help from someone with more regular expression mojo than I. I would like a somewhat efficient RE to find a string containing 8 to 12 digits with zero or more space or hyphen separators within the digits.

I can brute force it but I’m hoping for something more elegant.

Added:

Basically anything like:

123-456-78, 1-2-3-4-5-6-7-8-9-0-1-2, 12345678, 12345 67890

But I don’t want:

0-123456789012, 012345 6789012

(Sorry, editing on iPad)

You can try this which looks for a sequence of 8-12 digits with optional space or hyphen:

^(\d[\s-]?){8,12}$
