and it returns nothing

You should keep the ^ out of [A-Z] and change 4 to 3 as

Code:
 echo ABCD-12345 | grep '^[A-Z][A-Z]\{3\}-[0-9]\{5\}'

but the pattern

Code:
ABCD-12345

can come anywhere in code and also it can be preceeded with any character between [A-Z]

i tried this sol'n too

Code:
 
cat test2
ABCDE-12345
abc BCDA-12345
defe erjhj ABCD-12345
dfjfh sdhjh jkfgh dfj aaaAAAA-12345
