If you accidentally created duplicate Contacts, and have added records to more than one version of the Contact, you can merge the multiple Contacts together into one account.
The linked records from the duplicate Contacts will be moved over the main Contact, although you may need to manually transfer some information from the Contact edit form.
•To review what information is transferred during a Contact merge, see Merged Contact Information.
•To learn how to merge contacts, see Select & Merge Contacts.
