Definition of Device ID
A device ID is a unique identifier, typically a string of numbers and letters, that distinctly recognizes a mobile device such as a smartphone or tablet. In Android and iOS, device IDs have evolved as crucial tools for marketers, app owners, and developers alike.
The device ID serves as an invaluable asset in the world of mobile measurement, enabling marketers and app developers to track user behavior, enhance user experience, and refine their marketing efforts.
On platforms like Google Play, the device ID can be equated to the Google Advertiser ID, while on iOS devices, it’s often related to the Identifier for Advertisers (IDFA).
The introduction of Apple’s App Tracking Transparency and Google’s user privacy measures have further highlighted the significance of device IDs as they focus on user privacy and personalization.
5 Types of Device IDs
Device IDs act as distinctive fingerprints for mobile devices, assisting marketers, app owners, and developers understand user interactions. Over time, different types of device IDs have been introduced, catering to various platforms and needs. Let’s explore some of the predominant types of device IDs:
- Google Advertiser ID (GAID): Exclusive to Android devices, this ID allows marketers to track user activities and ad engagements. Users have the option to reset this ID or opt-out of personalized ads, promoting user privacy.
- Identifier for Advertisers (IDFA): Developed for iOS devices, IDFA is Apple’s response to the need for ad tracking while prioritizing user privacy. With Apple’s App Tracking Transparency, users can decide if they want to share their IDFA with advertisers.
- IMEI (International Mobile Equipment Identity): An identifier used primarily for security, IMEI is a unique number assigned to every mobile device, assisting in tracking lost or stolen phones. Unlike GAID or IDFA, IMEI remains constant and cannot be reset by the user.
- AppsFlyer Device ID: This is a proprietary device ID used by AppsFlyer, a mobile measurement platform. It assists marketers in app attribution, helping them understand where their app installs originate.
- Android ID: This is a unique ID for each device, generated automatically when users first set up their device. It can be altered by doing a factory reset.
How Does Device ID Work?
A device ID functions as a unique identifier, almost like a digital fingerprint, for every smartphone or tablet. When a user purchases and activates their device, it automatically generates this string of numbers and letters, ensuring it is distinct from any other device.
Mobile apps, particularly those requiring permissions for personalization or analytics, can retrieve the device ID to collect non-personal, anonymized data. This data offers insights into user behavior, aiding marketers in refining their advertising strategy.
Platforms such as Google Play and AppsFlyer use device IDs for better app attribution, ensuring advertisers recognize which marketing efforts are most effective. It’s crucial to note that while device IDs offer valuable user-level insights, changes like Apple’s App Tracking Transparency have introduced an opt-in requirement, ensuring user privacy remains paramount.
Role in App Attribution and Analytics
Device IDs play a pivotal role in app attribution and analytics, serving as integral tools for advertisers and app marketers. When a user installs an app or engages with an ad, the device ID aids platforms like AppsFlyer in tracing this activity back to its source. This enables advertisers to understand which advertising campaigns or sources drive app installs or conversions.
Furthermore, analytics tools use device IDs to gather aggregated data, providing a clearer picture of user behavior, such as funnel progression or drop off rates. This information is instrumental for app owners and marketers aiming to optimize the user experience or refine marketing efforts.
However, with the introduction of Apple’s App Tracking Transparency and similar initiatives, it’s essential to approach device ID use with respect to user privacy, emphasizing opt-in practices.

Privacy Concerns and User Control
The advent of device IDs has raised valid privacy concerns. These unique identifiers, which enable granular tracking of user behavior on smartphones and tablets, have been at the center of debates around user privacy.
Initiatives like Apple’s App Tracking Transparency (ATT) have pushed for more transparency and control in how apps access and use the device ID. Users now have the option to opt-in or opt-out of sharing their device ID on an app-by-app basis, ensuring more control over their personally identifiable information.
Moreover, the move towards aggregated data aims to offer a clearer picture of user behavior without compromising individual identities. As privacy becomes paramount, the emphasis on user control and protections, like limited ad tracking and the privacy sandbox, ensures that the balance between personalization and privacy is maintained in the digital world.

The device ID has emerged as a critical component in understanding user behavior, offering insights for advertisers and app marketers. However, with evolving privacy measures like Apple’s App Tracking Transparency and options to opt-out, the landscape continually shifts.
It’s imperative for stakeholders, from app owners to marketers, to stay updated and prioritize user privacy while harnessing the power of device IDs for effective marketing efforts.
