**TIN Unicity for Legal Entities**

We have introduced a uniqueness requirement for legal entity TIN (tax identification number- SSN, TIN) numbers. This change will prevent  legal entities with the same tax identification numbers to be created. The introduction of this change allows for customers to re-use individual legal entities as beneficial owners or control persons across multiple business legal entities.

When creating a business legal entity that shares a beneficial owner or control person with another business legal entity, you can simply pass in the legal entity ID in the business legal entity creation request.
