Why Can't I Delete My VPCs and Subnets?

If VPCs and subnets are being used by other resources, you need to delete these resources first before deleting the VPCs and subnets. This topic provides the prompts and the actions you need to take to delete the VPCs and subnets.

The VPC service has multiple resources. Some are free, while some are not. For details about VPC resource pricing, see Pricing Details.

If your VPCs and subnets cannot be deleted, submit a service ticket.
