What do you want to compare it against to check that it is unique?

Why not divide up your values to correspond to the date and time or think up
an algorithm that would generate an id based on the date and time. Then you
would be sure it is unique.

Paul,

here is one way to get a unique id by a column

=RANK(E1,$E$1:$E$10)+COUNTIF(E1:$E$1,E1)-1

Public Function rndString$()
Const ALPHNUM = "abcdefghijklmnopqrstuvwxyz1234567890"
Dim pos%, i%, res$
For i% = 1 To 12
If i% < 6 Or Rnd() < 0.5 Then
pos% = 27 * Rnd() + 1
res$ = res$ & Mid$(ALPHNUM, pos%, 1)
End If
Next i%
rndString = res$
End Function
