Identify Android AdIDs, Apple IDFAs and Safari IDs

Some exports of the Salesforce Audience Studio will contain mobile identifiers (MAIDs) like Android's AdID or Apple's IDFA, along with KUIDs and the client's first-party user IDs. Clients that use our hashed device ID will also see these IDs for some of their users. How can you tell which is which?


ID Type Example Comments
IDFA

Apple's iOS advertising IDs are called IDFA and follow this format, all in upper case

Unmanaged Safari (from event pixels, ad impressions) that is not in a first party context has uap_ as a prefix
Safari (AS Managed)
kppid_M6ubQ-Og
Audience Studio Managed IDs have kppid_ as a prefix
Safari (Client managed)
kppid_k1pid_kppid_i8tlxdjs109

Client managed first party IDs in Safari have the following prefixes

cookieName is the name of the cookie that you have provided Audience Studio to read. In the example, the cookie name is also kppid
