## Activating Cost Allocation Tags

If you see that Archera is not surfacing expected tags in the segment analysis flow, a common issue is that cost allocation tags are not activated in your AWS billing account.

To rectify this you can check if your account has activated cost allocation tags & if not then activate them following the [tag activation process from AWS](https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/cost-alloc-tags.html).

## Enabling Cost & Usage Reports

If you are seeing no tags available to activate in the AWS console you may need to ensure AWS Cost & Usage Reports are also enabled.

## Refreshing Tags

If the cost allocation tags are active and still not showing up in Archera you can refresh them on the AWS Console following this flow:

**Console → Billing and Cost Console → Navigation → Cost Allocation Tags → Refresh**

After activating/refreshing tags it can take up to **24 hours** for AWS to surface the data in their APIs and for Archera to reflect the changes in your dashboard.
