Customer list phone number got all mixed up

[VahidSamimi]

So I have a File A with a complete list of (By column) customer codes, customer names, ..., ..., phone numbers, fax numbers, ..., ...

When I sorted them all alphabetically, I must have not selected the phone numbers columns because they are now all mixed up.

I have 4 other files with the customer codes, customer names, and correct phone numbers but each file has 1/4 of the customers.

Is there a way I can copy from those smaller lists, and paste into the File A and it can find the correct customer codes and paste the correct phone numbers in the corresponding column?


UPDATE: The file attached is an example of what I have. Sheet 1 is the sheet I want to put the correct phone numbers into, Sheet 2 and 3 are examples of the other files I have with the correct phone numbers corresponding to the correct customer names/codes.
