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 based on the prompts on the console before deleting the VPCs and subnets. This following provides detailed deletion prompts and corresponding deletion guide.

VPCs and subnets are free of charge.

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