Potential Matching Records
When adding a contact or account, you can compare the contact or account you are adding to contacts or accounts that exist in the database. If a record exists in the database with the same information, you can avoid having duplicate records. If you choose to use a matching account, the account information will be added to the account boxes in the Contact/Account Information dialog box. If the contact or account information does not match, you can continue adding your contact or account.
Note: Matches on phone numbers do not require an exact match.
The area core or country code and next 3-digits must be an exact match, but the
remaining numbers do not have to match exactly in order to be returned as a
potential matching record.
