A Marketing Cloud admin wants to check the status of a Salesforce contact in All Subscribers. The account is connected to their Salesforce org via Marketing Cloud Connect.
Which subscriber key should be used to search for the contact in All Subscribers?
In the context of Marketing Cloud Connect, the subscriber key used to track Salesforce contacts in All Subscribers should be the 18-digit Contact ID. This ID ensures that the record can be uniquely identified across both Salesforce and Marketing Cloud, as the 15-digit ID is case-sensitive and may not be unique. The 18-digit ID is a canonical form in Salesforce best practices, ensuring accurate referencing and integration.
Should be B. 18-digit Contact ID https://help.salesforce.com/s/articleView?id=sf.mc_co_salesforce_data_extensions.htm&type=5
"Use an 18-digit Salesforce Contact or Lead ID (not 15-digit) to map to the subscriber key." https://help.salesforce.com/s/articleView?id=sf.mc_co_salesforce_data_extensions.htm&type=5
B is correct.
