Cross Account Alias Records

Is it possible to create an Alias record in Route 53 to a resource in another AWS account?

Use Case:

I have 2 AWS accounts. My domain is configured with a hosted zone in account A and I have an ELB in account B. I want to create a record to my ELB in account B for my domain's zone apex - which has to be configured in account A.

Does anyone know how I can get around this? I know I can go through billing support to have the domain transferred to account B but I would prefer not to do this. Also, it is not viable for me to migrate the resources from account B to account A.

I can confirm this is still working, it's just the docs and UX of the portal are terrible.

I wanted to create a CNAME to an ALB at the apex (root) of my hosted zone; this isn't allowed so using an Alias A record instead. My ALB is in a different account, so the UI makes you think you can't do it... but you can.

You can create an Alias record to an ALB/ELB in another account by just pasting into the 'Route traffic to' box. Choose the region, then just dump the address into the box. Now this UI element makes you think it's a normal picklist and you can only pick from valid values... but it is secretly also a textbox allowing you to enter arbitrary text. Great UX guys

So enter your address and just click 'Create records'.

For those who're looking for why it doesn't work after you followed the procedure:

that is probably that you have another domain in the other account, in this case, don't forget to add a listener rule to the target ELB.
