Contact UUID (universal unique identifier) is an identifier for contacts in your system.

• X-CD uses this field internally for tracking and matching purposes.
• You will see this field displayed near the top of a contact profile. In addition, this field is included in some of the contact module reports/download files.
• A contact's UUID is useful when using the update contacts option on the import Contacts screen.
• If you export contact data from the contacts module, you will see the contact UUID in the file.
• You can then copy/paste some of the data in to the "contact import" template used by the system.
• If you include the contact UUID value in the import file, then the system will know that you are actually trying to update an existing contact.
• Using the contact UUID with the contact import function, allows you to batch edit your contacts safely.
