Conditional formatting to Match Values in a List

I have 2 lists of code. How to use conditional formatting to highlight code in List 1 which appear in List 2 if the first 3 characters in List 1 match with List 2.

List 1:
A01
A02
A0876
B89
B764
C7821
C54
C09
D349
D76
E456
G39
Y467
Y32
Y7834

List 2:
A08
B89
C09
D34
Y78

Thank you for your help!

Administrative Note:

Welcome to the forum.

We would very much like to help you with your query, however the thread title does not really convey what your request is about.

Please take a moment to amend your thread title. Make sure that the title properly explains your request. Your title should be explicit and not be generic (this includes function names used without an indication of what you are trying to achieve).

Please see Forum Rule #1 about proper thread titles and adjust accordingly. To edit the thread title, open the original post to edit and then click on Go Advanced (bottom right) to access the area where you can edit your title.

(Note: this change is not optional. As you are new here, I have done it for you this time.)


Will you please attach a small sample Excel workbook? We are not able to work with or manipulate a picture of one and nobody wants to have to recreate your data from scratch.

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired results are also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment (it hasn't worked for years, and despite our repeatedly asking the technical team who own the forum to fix it, they can't be bothered to do so), so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.

Use this as the CF formula:

=SUMPRODUCT(--(NOT(ISERR(SEARCH($C$2:$C$6,A2)))))>0

Thank you very much Glenn! The formula works perfectly.

You're welcome.
