Hopelessly confused... where do these 'Digital Rights' codes go?

[Katsaurs]

Ah, they did throw a notice/warning up about it on the store page [here] (Click important notices at the bottom of the page and read the Collector's Edition Digital Upgrade Service blurb).

But in terms of contacting support, being in the EU myself I usually speak to them via webchat during working hours as its much faster to get a response. You can email and/or call them, I'm trying to grab the page link for you to use but at the moment support page is having issues

Sorry but nowhere does it state in the important notices regarding applying full CE codes on to standard accounts. Most of it is about playing cross platforms. It does mention the upgrading to CE but like I stated nowhere does it forbid using full CE codes.

You're correct, it doesn't mention/forbid you from using the CE digital code but this bit here:

The Collector's Edition digital upgrade offers customers the ability to upgrade their standard FFXIV account to digital Collector's Edition status

Says to me that in order to actually get the CE perks, you need to upgrade your standard account using the upgrade option, not the full purchase option; hell it even gives you the upgrade price in the pricing box too:

Collector's Edition Digital Upgrade** (Requires Base Game) £14.99

In buying the full purchase option you're essentially buying another service account, I know it sucks and a bit convoluted but they did mention it multiple times on the beta forum in the purchase queries thread

Note: Not trying to be an ass here, it's hard to get across tone in text
