This is still a bit confusing, Amanda.

If your drop down in G3 is a data validation drop-down, where you have
confined the answers to be only those contained in a list, then the list
would be somewhere else - assume this is B3:B210, so that next to it in
C3:C210 you have the numbers that are associated with those codes.

If this is the case then in H3 you would have this formula:

=VLOOKUP(G3,B$3:C$210,2,0)

Hope this helps.

The drop-down list is in G3. And the cells that the 207 #s are in are
C3:C210.

You would normally use a VLOOKUP formula in H3 to do this, but you
will need to give a few more details about your data before I could
suggest a formula. For example, where is the drop-down list, and which
cells are the 207 numbers located in?

I am trying to find a formula that can autofill H3 when G3 is a certain
value
picked from a drop-down list. For example: I picked 52109706AB from a
drop-down list in G3. I need H3 to auto-populate with 1452-AA.
However, G3
might not always be 52109706AB. It might be one of the 207 numbers
within
the drop-down list, so then H3 would auto-populate with the
corresponding
number, using the data within the drop-down list. I hope this makes
sense,
and I hope that someone out there can help me.
