# Getting an existing ARN for Amazon RDS
<a name="USER_Tagging.ARN.Getting"></a>

You can get the ARN of an RDS resource by using the AWS Management Console, AWS Command Line Interface (AWS CLI), or RDS API. 

## Console
<a name="USER_Tagging.ARN.CON"></a>

To get an ARN from the AWS Management Console, navigate to the resource you want an ARN for, and view the details for that resource.

For example, you can get the ARN for a DB instance from the **Configuration** tab of the DB instance details.

## AWS CLI

To get an ARN from the AWS CLI for a particular RDS resource, you use the `describe` command for that resource. The following table shows each AWS CLI command, and the ARN property used with the command to get an ARN.

For example, the following AWS CLI command gets the ARN for a DB instance.

**Example**  
For Linux, macOS, or Unix:  

```
aws rds describe-db-instances \
--db-instance-identifier DBInstanceIdentifier \
--region us-west-2 \
--query "*[].{DBInstanceIdentifier:DBInstanceIdentifier,DBInstanceArn:DBInstanceArn}"
```
For Windows:  

```
aws rds describe-db-instances ^
--db-instance-identifier DBInstanceIdentifier ^
--region us-west-2 ^
--query "*[].{DBInstanceIdentifier:DBInstanceIdentifier,DBInstanceArn:DBInstanceArn}"
```
The output of that command is like the following:  

```
[
    {
        "DBInstanceArn": "arn:aws:rds:us-west-2:account_id:db:instance_id", 
        "DBInstanceIdentifier": "instance_id"
    }
]
```
