Hi,

Allowed are all numbers and two spaces
not allowed every other character

Can someone help

Are the spaces always in the same place, or can they appear anywhere in the string?

Try:
^\d{4}\s\d{3}\s\d{5}$

You're welcome!
Assuming any sequence of digits, no leading nor trailing nor consecutive spaces allowed, then the following should do:
^(?:\d+ ){2}\d+$
Cheers
Andi
