What is the Identifier for Vendor (IDFV)?
The Identifier for Vendor (IDFV) is a unique identifier that is assigned to an app on a device. It is used to identify the app and distinguish it from other apps on the same device.
What is Identifier for Vendor (IDFV) used for?
The IDFV is used to track and manage the vendor's data on a device. It is typically used in conjunction with other identifier values, such as the Identifier for Advertisers (IDFA), to provide a more complete picture of the vendor's activity on the device. The IDFV is typically used for iOS devices to track the usage of an app on a particular device. An example for this is when an app developer may use the IDFV to track how often an app is used on a particular device, or to identify a device that has used the app in the past.
The IDFV is unique to the app and device combination. This means that the same app on two different devices will have different IDFVs. Additionally, the IDFV is also specific to the vendor of the app, so two different apps from the same vendor will have different IDFVs even if they are installed on the same device.
What is the difference between IDFA and IDFV?
The IDFA is a unique identifier that is assigned to each device and is used to track the device for advertising purposes. It is used by advertisers to track the effectiveness of their advertising campaigns and to show personalized ads to users. The IDFV, on the other hand, is a unique identifier that is assigned to an app on a particular device, and is used to identify the app and distinguish it from other apps on the same device. It is typically used to track the usage of an app on a particular device.
However, with the tracking limitations placed on IDFA today, Tenjin defaults to IDFV, which means that if the user opts-out of tracking or opts-in at a later stage, we would still register the user with IDFV to avoid inaccuracies.
What is the Android equivalent for IDFV?
The Android equivalent of the Identifier for Vendor (IDFV) is the Android ID. The Android ID is a unique identifier that is assigned to each Android device and is used to identify the device. It is generated when the device is first turned on and remains the same for the lifetime of the device.
Like the IDFV, the Android ID is used to identify a particular device and distinguish it from other devices. It is important to note that the Android ID can be reset if the device is factory reset.
