Accepted Answer

I hope I can shed a little light into this topic.

The [Amazon Resource Name](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference-arns.html) (ARN) is used to uniquely identify AWS resources. A Uniform Resource Identifier (URI) provides a name to an accessible resource.

In S3, the URI is a resource identifier within the context of the S3 protocol. It is used for API access to said files. There is some more details regarding [this here](https://repost.aws/questions/QUFXlwQxxJQQyg9PMn2b6nTg/what-is-s-3-uri-in-simple-storage-service) on an already answered post.

In a summary of the differences, an ARN is used within the AWS Cloud infrastructure to identify/access resources, while the URI is used externally identify/access these resources via APIs.
