using zgrep to find phone numbers in a directory

Question

I need to create a script that will search for US phone numbers in files that are in a directory that has been passed in as a parameter to your script. The script must recognize phone numbers in the following formats: (570)555-1212, 570.555.1212, 570-555-1212, and +1.570.555.1212. My script should also be able attempt to minimize false positives. The script should work on files that are compressed or uncompressed.

The output should be similar to the following.

letter.docx: (312)555-1212 570.389.3000

intro.txt: 570-389-3000

I have no idea where to start other than

#!/usr/bin/bash
zgrep -e 1 -q '[0-9]{3}-[0-9]{3}-[0-9]{4}','[0-9]{3}.[0-9]{3}.[0-9]{4}','+1.[0-9]{3}.[0-9]{3}.[0-9]{4}'

if [ $? -eq 0 ] ; then echo matches ; else echo "no match found" ; fi
