Make a custom property unique

Make it possible to define a custom property as a unique field.


Meaning when a data is entered into that field, if it exists in another contact it will alert you of that (like it does for the email field)

Upvote for this idea. We need a unique property for contacts as well. Now a unique property is available for Ticket and Custom object but not yet for contacts and companies.

Hey Shay,

Any news on when this is going to happen for the Contacts object? We have
several clients today that this would be helpful with.

I think message got lost in translation.  It looks like majority of people are looking for the unique field for Contacts and not Company. Correct me if I'm wrong but it looks like this feature is delivered to everything except the Contacts. Is it intentionally not added to Contacts for some reason?


@shajones I agree with WTrinh that this feature is available for every record type except the one that was requested. For some reachouts we only use LinkedIn and thus have no email address for a contact. A LinkedIn profile URL is a unique indetifier for a contact as no one will have the same. Because we're unable to create unique value properties for contacts we can't import lists or sync with other tools that have lists based on LI profiles.


I can also see phone numbers being a reasonable basis for unique identifiers.


When can we expect this feature to be available for contacts?
