IDFA is the abbreviation for identifier for advertisers on iPhones. An IDFA is somewhat analogous to an advertising cookie, in that it enables an advertiser to understand that a user of a phone has taken an action like a click or an app install. That is called ad tracking. IDFAs take the place of cookies in mobile advertising delivered to iOS devices because cookies are problematic in the mobile world. Advertisers are naturally interested in understanding the anonymized individuals that take advertising actions.

Third-party cookies, which are commonly used on the PC web for tracking, tend to have short life spans — anything from one to thirty days on average. Few consumers feel a need to take this action, so IDFAs can offer a better foundation for a persistent and anonymized consumer profile. A UDID was a permanent device number, and sharing it could not be turned off, whereas users have the option to limit ad tracking, or to change their IDFA periodically.

This reflects their commitment to the ideas of privacy and choice, while also enabling a robust advertising industry in which brands target likely responders and drive revenue for app and mobile publishers. Users that choose to can limit ad tracking by preventing the IDFA being passed to advertisers.

When consumers take actions because of ads, like clicking a banner, playing a video, or installing an app, media companies can pass the IDFA with information about the consumer action that took place because of the advertising.

Most media companies do pass IDFAs. Some media companies, including some large social networks, do not pass device IDs to advertisers, but do allow you to target specific IDs within their properties. Many companies also leverage IDFAs as a tool for fraud detection. By monitoring the stream of ad actions and associated IDFAs, advertisers get important signals that may indicate advertising fraud.

This stands for identifier for vendors. An IDFV is assigned and shared by all apps from the same company. Sometimes companies with multiple apps base their marketing efforts and analyses on IDFV, because they only change if a user uninstalls all apps from a particular vendor.

Using IDFAs and app attribution capabilities like those offered as part of the Singular platform, marketers can understand which campaigns, executions, and media partners were responsible for desirable consumer actions.

Using these insights, they can calculate the ROI for every program and tactic and optimize their marketing to the most profit-generating tools. The IDFA also enables a marketer to target specific individuals that have taken actions in the past.

For example:. This sort of individual targeting is becoming increasingly common as programmatic media and social media advertising grow in popularity.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

It seems from the examples in Advertising ID Documentation that GAID is stored lowercase, the last example also shows a wrapper class which might mean you don't have to worry about this.

With regards to the Apple version I could not see any examples in their own documentation, but the example shown on Possible Mobile 's article on Unique Identifiers shows it in Uppercase. I don't know the site to say whether thats actually a reliable source.

Below are instructions to find your device's options to set an opt-out flag, which applies to companies that participate in the mechanism. Some companies may offer additional or alternate mobile choices depending on their technology. You should contact the owner of the opt-out mechanism if you experience any issues with the opt out mechanism. You should contact the Digital Advertising Alliance or TRUSTe if you have any questions or concerns regarding the opt-out applications operated by them.

Please note that the NAI does not operate or maintain any of these opt-out mechanisms for mobile applications. Most companies will apply an opt-out preference for a mobile advertising identifier to certain data collection practices across applications for that device, but not the data collection and use on any other device.

Additionally, the privacy settings for the web, accessed via your device's browsers, are typically independent from the privacy settings tied to your mobile applications. Meaning, it is unlikely that a company will be able to connect your mobile applications' opt-out with your mobile browser.

We need to understand how these limitations impact the marketing community, and just as importantly, measure the risks of circumvention.

Broadly speaking, the three most important limitations of iOS for marketers, are:. This is the beginning of a three part series addressing each of these limitations in turn. A robust and rather one sided debate is underway about whether these limitations imposed by Apple are appropriate, proportional, competitively driven, consumer interest driven, etc.

Traditional web cookies do not work for state management on native applications for either Android or iOS. Without state management, advertisers cannot build profiles for targeting or engage in basic cross-application measurement, optimization, or attribution.

Fortunately, both operating systems provide a centrally managed unique device identifier that advertisers can use for cross-application state management.

Apple Developer Documentation

IDFA quickly replaced permanent identifiers and other awkward work arounds paste board objects, etc. IDFA was built with specific user privacy features in mind and has succeeded in replicating many of the privacy features of the desktop cookie based system.

For state management across native applications, IDFA works beautifully. Its main limitation is that it does not extend to iOS Safari. This is is especially troubling for advertisers seeking to understand the customer journey from advertisement to final action. Whenever the user takes a path that includes Safari, the chain of tracking and attribution is broken. Using alternative state management techniques.

It is very difficult to argue that a typical consumer understands the nuanced power and limitation of IDFA as a state management tool and in particular, how ad related tracking happens, and is fine, throughout the in-app journey, and then suddenly breaks at the Safari border, even when the user is unaware that they have transitioned to Safari.

This argument is even stronger when the application of the data is simple ad attribution, rather than profile assembly for targeting. First of all, recall that Mr. Legal; 5. So we need consent for tracking associated with a state management device, whether that device is IDFA or a statistical ID.

But there is no specific statement about IDFA alternatives here, so everyone is in the same boat. Of course, existing industry standards require that statistical IDs be specifically called out in privacy policies.
