I'm trying to match 'ABCD 252'.
There is a variable number of spaces before the 2.
The 252 could be any number.
I tried:
grep 'ABCD[:blank:]+[:digit:]+' file
For simple "existence" matching I'd use
grep 'ABCD *[0-9]'
(note the two spaces). There's not need to match any more than one
digit. If you really do need to match the whole sequence of digits:
grep 'ABCD *[0-9][0-9]*'
