Refer AWS Account number inside IAM policy

Question

For the sake of the automation, I want my IAM policies to be generic.

I am aware that ${aws:username} fetches username of the policy to whom it is applied to.

Is it possible to do the same for AWS Account number arn:aws:iam::1234567890:user/${aws:username} with something like this arn:aws:iam::${aws:accountnumber}:user/${aws:username} inside an IAM policy.

Edited: Allowed variables are listed in the document linked below. https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_variables.html

Answer 1

AWS IAM Policy Variables does not allow references for AWS Account Names. Hence there is no alternative to dynamically refer the account number in the IAM policy.
