Works for me:
[eben@pc eben]$ let foo=5678901234
[eben@pc eben]$ echo $foo
5678901234
[eben@pc eben]$ if [[ $foo -gt 5678901233 ]] ; then echo yes ; fi
yes
[eben@pc eben]$ echo $BASH_VERSION
2.05b.0(1)-release
[eben@pc eben]$ cat /etc/redhat-release
Red Hat Linux release 8.0 (Psyche)

You could split the area code from the rest, and test them separately.
Instead of "$pnum -eq $ppnum" you'd have "$pareacode -eq $ppareacode -a
$prest -eq $pprest", but I would look into the way you read or test the
numbers. Check the actual values used in the comparisons.
