BlackBerry 10 OS introduces the ability to link multiple contacts from different accounts (Microsoft Exchange ActiveSync, CardDAV, Local Contacts, and SIM Card) into one unified contact.

BlackBerry 10 OS includes logic that is used in order to automatically link these contacts together.

Contacts will automatically form a link if they share the same information for any of the following:

  • First and Last name
  • Email address
  • Social networking profile (for example, same LinkedIn, Twitter, or Facebook profile)
  • Mobile Phone number
  • PIN
  • BBID email address

Contacts who share the same account source, however, are not automatically linked. For example, if a single CardDAV account has two contacts who share the same first and last name of Justin Jones, these contacts will not be automatically linked. A consequence of this behaviour is that any contact created on the smartphone will not automatically link with any existing contacts in writable sources. This will also result in contacts which are created on the smartphone being written to all writable accounts.

CollapseAdditional Information

The Mobile Phone number is used as linking criteria due to the fact that it is more unique. Other types of phone numbers are not used for linking due to them often being shared between multiple people (for example, a home phone number).

Any contact that has been manually linked or unlinked at some point becomes ineligible for automatic linking. This helps prevent undoing any link corrections made by the user.
