you need to add some quantifiers and limiters in there

Code:
sed 's/.*\([0-9]\{3\}-[0-9]\{4\}-[0-9A-Z]\{3\}\).*/\1/'

which will look for anything followed by \( exactly 3 digits followed by a - followed by exactly 4 digits, followed by a - followed by a combination of 3 letters and/or digits \) followed by anything and replace it all with the part above in \( .. \)
