IDFA/GAID letter case

Leave a Comment

Is there a standard/convention regarding the letter case of IDFA (Identifier for Advertising) and GAID (Google Advertising ID)?

I couldn't find anything conclusive about this. Links to relevant documents will be appreciated.

From what I've seen, IDFA is uppercase and GAID is lower case. Sorry, no links.

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. Like Android, Apple has some wrapper classes which seem to provide the ID to you so you again might not need to worry about formatting.
