I have the two tables below.

Prefixes
PN
SN
DN

Values Valid
PN001 T
PA123 F
SN654 T

I am trying to determine if my value in the second table has the proper prefix in it which are defined in the first table and if so then indicate that the value is valid. I have looked at the FIND, VLOOKUP, MATCH, etc to see if I can find something to work and I am drawing a complete blank. Basically I was hoping for something like this =FIND(B3:B5,B11), but that would have been too easy.

Is there a way that I can do this using a formula?

Thanks
