here's an apex class that will return a unique 16 digit ID:

 

global class GuidUtil {

    private static String kHexChars = '0123456789abcdef';

    global static String NewGuid() {

        String returnValue = '';
        Integer nextByte = 0;

        for (Integer i=0; i<16; i++) {

            if (i==4 || i==6 || i==8 || i==10)
                returnValue += '-';

            nextByte = (Math.round(Math.random() * 255)-128) & 255;

            if (i==6) {
                nextByte = nextByte & 15;
                nextByte = nextByte | (4 << 4);
            }

            if (i==8) {
                nextByte = nextByte & 63;
                nextByte = nextByte | 128;
            }

            returnValue += getCharAtIndex(kHexChars, nextByte >> 4);
            returnValue += getCharAtIndex(kHexChars, nextByte & 15);
        }

        return returnValue;
    }

    global static String getCharAtIndex(String str, Integer index) {

        if (str == null) return null;

        if (str.length() <= 0) return str;    

        if (index == str.length()) return null;    

        return str.substring(index, index+1);
    }
}
