Cost allocation tags View is not showing up newly created user-defined tag

Question

I created a new tag for a resource and when i go to Cost allocation tags View, under Billing  that tag is NOT available to activate. What is the reason?

Note : i have already enabled Cost Explorer, Budget, Cost and Usage Reports Views

Accepted Answer

I figured out that After you create and apply user-defined tags to your resources, it can take up to 24 hours for the tag keys to appear on your cost allocation tags page for activation. It can then take up to 24 hours for tag keys to activate.

Hi,

You have to activate your user-defined tags in billing to make them visible in cost allocation: https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/activating-tags.html

Did you do that activation?

Also be aware of differences between the different services that you use: see https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/custom-tags.html

```
Note
The behavior of cost allocation tags varies across AWS services. To learn more about the 
cost allocation tag behavior for a supported service, refer to the service’s documentation. 
For example, to learn more about using cost allocation tags with Amazon ECS, see Tagging 
your Amazon ECS resources in the Amazon Elastic Container Service Developer Guide.
```

Best,

Didier

Answer

To activate tags, it has to be visible in "Cost allocation tag" page  in billing.
This question is why tag is not visible there for activation?
