# IAM Role

## Resource Type

`AWS.IAM.Role`

## Resource ID Format

For IAM Roles, the resource ID is the ARN.

`arn:aws:iam::123456789012:role/example-role`

## Background

An IAM role is an IAM identity that you can create in your account that has specific permissions. AWS Users and services can then assume the role in order to gain those permissions. An IAM role is similar to an IAM user, in that it is an AWS identity with permission policies that determine what the identity can and cannot do in AWS.
