Matching data in 2 separate excel tabs

• I have 2 tabs of data (multiple columns, multiple rows)
• each of these tabs contains a column with only the street address (ex: 123 Somewhere Street), no city, st, zip)
• on tab A, all street address fields are entered so there no blanks
• on tab B, there could be blanks in this street address column

I'm trying to see if an address in street address column on tab A matches exactly to a street address on tab B and either use another column to say true or false on Tab A, or even better, highlight the matching text on both tabs.

Any clue how to accomplish this?
