How do I isolate a character string of only numbers with varying starts and ends?

[#1]

Hello,

I am trying to isolate only the 12 digit string for each Name to give me what you see in column Name 1. Is there a regex formula I could use to take care of the front and back end? Any help would be appreciated. Thanks!

something like \d{12} might work

Names Default To Here(1);

a = "0123456789123 123";
b = "123 0123456789123";

Show(Regex(a, "\d{12}"));
Show(Regex(b, "\d{12}"));
