Honor all your customers by using titles that align with their identities. The Mx. Salutation picklist value is now available by default. You can customize the Salutation field to include other nonbinary or honorific titles specific to your company. Be sure to review any privacy implications before collecting gender-related data.
Where: This change applies to Lightning Experience, Salesforce Classic, and all versions of Salesforce mobile in all editions.
When: All Salesforce instances created in Summer ’23 or later have Mx. as a standard Salutation picklist value. If your org was created before Summer ’23, add the Mx. value manually.
How: From Setup, use the Object Manager to manage Salutation picklist values on the Individual, Lead, Contact, and Person Account objects.
