# Managing VPC Tags

#### Scenarios

A VPC tag identifies a VPC. Tags can be added to VPCs to facilitate VPC identification and management. You can add a tag to a VPC when creating the VPC, or you can add a tag to a created VPC on the VPC details page. A maximum of 20 tags can be added to each VPC.
