>How can I know if a variable is exactly 6 digit long?

  if ($str =~ /\A\d{6}\z/) { ... }

The \A matches the beginning of the string, \d{6} matches 6 digits, and
the \z matches the end of the string.

If you meant "characters" instead of "digits", don't use a regex at all.

  if (length($str) == 6) { ... }
