or
if (eregi("[^[:digit:]]{3}",$co_area))
if you use the POSIX regex fields.

First mistake when using character classes in the pattern is that the
hyphen must be at the end if it is to be included. Otherwise the hyphen
is seen to be part of the range (0-9 or A-Z):
so, ^[0-9a-zA-Z._-]{3,12}
instead of what you have. You also should not need the trailing $.
As in the first example, don't use the 'double negative' approach.
use:
if (eregi("^[^0-9a-zA-z._-]{3,12}",$nickname)) {
echo "only alphanumeric buddy!";
}
I didn't test this but it should be closer to success.
