Uniqueness of AWS resource ids

Question

Each resource has their own Unique ID in format specified [here](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/resource-ids.html).
How unique are these Unique ID, are they unique **Globally** for **all** AWS accounts or specific to account or region?
And are there any chance for this ID to repeat (in case if resource is deleted).
Could anyone clarify me on this?

Answer

Hi,

[Amazon Resource Names (ARNs) uniquely identify AWS resources. They are composed by partition, service, region, account-id, resource-id (and sometimes with resource-type).
](https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html)

In some services the resource-id can be the name of the resource, so the only thing that can differentiate is the  partition or region, for example, two SQS with the same name, in the same account, but in different regions:
* arn:aws:sqs:us-east-1: 555555555555:teste-43523523543
* arn:aws:sqs:us-east-2: 555555555555:teste-43523523543
