customer Name against Unique customer number count

[Nelson]

I have a unique count of customer numbers (Z1 : Z100) now I want to get the
customer number associated to this number the customer names reside in B1:100)

I can't use another Unique filter because sometimes the customers name is
spelled in lower case or upper case or has "inc, corp" in it etc but is the
same customer.

what would I use?

Thanks in advance

Since there are only 100, I would sort them alphabetically, delete the
repeats. 100 should not be that bad ;-) If it were 10,000 might be another
story.

wont work, This is a template for another 6 tabs and growing each tab
contains lots of product data each tab needs to auto generate unique customer
numbers counts and unique customers by product version.

These numbers get rolled up to a summary page
