I'm trying to de-duplicate and prevent duplicate leads in SFDC based on Phone numbers. I created a matching rule for Phone field with "exact" match.
However, I found that it's allowing duplicate records with phone numbers which are just formatted differently:
1) (206) 251-7000
Why is that so? I though field of type "Phone" will automatically format any 10 digit number to (xxx) xxx-xxxx given the locale is set to English (USA)
