In my worksheet/form a user enters a policy number in B5 to search for
details.
B6 holds the vlookup formula which displays their info.

But if a non-existing policy is entered in B5, B6 shows the next closest
match. How do I force an exact match & give some sort of error message when
an invalid # has been entered ? Thanks!

=VLOOKUP(B5,List2,2)

Check the help file under VLOOKUP.


Syntax

VLOOKUP(lookup_value,table_array,col_index_num,ran ge_lookup)

Range_lookup is a logical value that specifies whether you want VLOOKUP to find
an exact match or an approximate match. If TRUE or omitted, an approximate match
is returned. In other words, if an exact match is not found, the next largest
value that is less than lookup_value is returned. If FALSE, VLOOKUP will find an
exact match. If one is not found, the error value #N/A is returned.
