Still needed…! 
Major need!!!
Just came across another client who has had to put multiple workarounds in place to solve this.
would be great to have this natively as well!
this is a basic and essential feature that is required. Data privacy is such a crucial requirement for any SaaS system that is being adopted by a company.
This is very necessary. A Contact can have many phone numbers, even WhatsApp phone number. Creating a custom property requiring unique value cannot solve the problem completely. It is best to have a deduplicate mechanism by Phone number, similar to Email. You should even use only 1 property and store many phone numbers simultaneously.
Much needed to prevent further duplications in Salesforce.
Much needed to prevent duplicates in Salesforce for those that don’t have an e-mail.
They have this its an upsell to another product. I have the same problem as we are a phone based company so most of our outreach starts via phone so it has becomoe our unique identifier. Then formatiing of the numbers becomes the issue. We NEED a better solution
how are we in 2026, 7 years after this feature was initially requested and 70 comments later, and somehow this hasn’t been implemented yet? this is mandatory for some of us.
