Generate unique user id with each addition of data

As I add new data to database.txt I want to generate a unqiue User Id. This is my current solution.

Code:
echo $RANDOM:$lname:$fname >> database.txt

But I seem to have problems when I try and use $RANDOM for formatting like so:

Code:
grep "^4539" database.txt | awk -F":" '{print "User ID:\t"$RANDOM"\nLast Name:\t" $lname"\nFirst Name:\t"$fname}'

How can I generate a unique user id another way. Where the variable can be used for piping and formatting?
