How to identify object type using contactkey in marketing cloud?

Question

I've synchronized two objects (from sales cloud) as Contacts in salesforce marketing cloud. These two objects are "Lead" & "Account" and both are mutually exclusive.

I want to update bounce status in sales cloud at Lead & Account level respectively. "_bounce" data view available in marketing cloud only provides subscriberkey (which is contactkey as well in this case) and doesn't tell me if the particular contact belongs to "Lead" object or "Account" object.

When I create journey in journey builder to update bounce status in sales cloud, how do I identify object type (Lead or Account) against contactkey and accordingly update respective object.

Answer 1

Contact ID's are starting with 003 and Lead ID's are starting with 00Q.

• Example Contact: 0030X00002EYLjkAYG

• Example Lead: 00Q0X00000YRg0VNGH

This is probably the easiest way to differentiate them without doing any lookups to cross-reference data.

Answer 3

These two answers cover the topic pretty well but I just wanted to add that you can use getSObjectType method to determine what is the object type behind SFDC Id:

Id unknownObject = '0030X00002EYLjkAYG';
System.debug(unknownObject.getSObjectType());
