# Use `TagResource` with a CLI
<a name="example_lambda_TagResource_section"></a>

The following code examples show how to use `TagResource`.

------
#### [ CLI ]

**AWS CLI**  
**To add tags to an existing Lambda function**  
The following `tag-resource` example adds a tag with the key name `DEPARTMENT` and a value of `Department A` to the specified Lambda function.  

```
aws lambda tag-resource \
    --resource arn:aws:lambda:us-west-2:123456789012:function:my-function \
    --tags "DEPARTMENT=Department A"
```
This command produces no output.  
For more information, see [Tagging Lambda Functions](https://docs.aws.amazon.com/lambda/latest/dg/tagging.html) in the *AWS Lambda Developer Guide*.  
+  For API details, see [TagResource](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/lambda/tag-resource.html) in *AWS CLI Command Reference*.

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: Adds the three tags (Washington, Oregon and California) and their associated values to the specified function identified by its ARN.**
