The ad identifier – aka “IDFA” on iOS, or “AAID” on Android – is the key that enables most third-party tracking on mobile devices.
Disabling it will make it substantially harder for advertisers and data brokers to track and profile you, and will limit the amount of your personal information up for sale.
What is Gaid and IDFA
Each smartphone is uniquely differentiated from hundreds of millions of other smartphones by something called an ad ID.
Google’s version is known as GAID (Google Advertiser Identification) and Apple’s is called IDFA (Identifier For Advertisers).

Identity for advertisers (IDFA) An IDFA is a unique, random identifier that Apple assigns to every device.

Neither identifier is particularly easy to find, and both can be reset.
What will replace IDFA
AppTrackingTransparency framework (ATT), just like IDFA, is an Apple thing. Introduced at WWDC 2020, this mechanism will manage user consent for ad tracking starting iOS 14.5 update.
Among other things, ATT will handle users’ permission for the usage of their IDFAs.

Apple said today that the privacy changes to its Identifier for Advertisers (IDFA) in iOS 14 are coming during the week of April 26 with its next operating system software release.

Does Android have an IDFA

When did Apple implement IDFA
On September 3, 2020, Apple announced plans to restrict access to IDFA and require websites and apps to obtain an explicit permission from users before being granted access to IDFA.

Apple is deprecating the IDFA, making it an opt-out by default and eliminating the ability for fingerprinting without user consent.
Google will follow by deprecating GAID (Google Advertising ID”) soon enough. User level tracking and attribution becomes obsolete.
How does IDFA tracking work
IDFA stands for Identifier for Advertisers. It’s a unique tracking system that assigns a random ID number to each iOS device.
It is used for tracking user activity (such as monitoring the ads that they interact with) and works in much the same way that browser cookies do when tracking online activity.
What are Apple’s IDFA changes
The Latest Changes to IDFA Apple users can choose to block the sharing of this unique identifier at the App level.
Previously, consumers had to opt-out. Now, when a user installs or updates the new iOS, a prompt will appear alerting the user to opt-in or opt-out of the sharing of this information.
What is IDFA and why Apple killed it
Apple created the IDFA years ago so that mobile marketers could attribute ad spend.
The IDFA allows publishers and advertisers to track users through their unique mobile device ID, and connect a click on an ad with an app install at a later point in time, so results from marketing campaigns can be measured accurately.
Does Apple still use IDFA
If you talk to most advertisers, they will tell you that with Apple’s release of iOS14.
5 on April 26th, 2021, Apple essentially declared the end of IDFA.
How is IDFV used
