# CreateVpc

## 1. API Description

This API (CreateVpc) is used to create a VPC.

#### Prerequisites

Before creating a VPC, call [`DescribeVpcAvailableRegions`](/api-reference/compute/bmc/vpc/describevpcavailableregions.md) to check the availability regions for VPC creation.

{% hint style="info" %} <mark style="color:blue;">**Note**</mark>

* <mark style="color:blue;">The quantity of VPCs you can create in one availability region is limited. If you need more, please contact Zenlayer Support.</mark>
* <mark style="color:blue;">This API is an async API. A VPC ID list is returned after the creation request is sent. However, it does not mean the creation has been completed. The status of the VPC will be</mark> <mark style="color:blue;">`CREATING`</mark> <mark style="color:blue;">during the creation. You can use</mark> [<mark style="color:blue;"><mark style="color:purple;">DescribeVpcs<mark style="color:purple;"></mark>](/api-reference/compute/bmc/vpc/describevpcs.md) <mark style="color:blue;">to query the status of the VPC. If the status changes from</mark> <mark style="color:blue;">`CREATING`</mark> <mark style="color:blue;">to</mark> <mark style="color:blue;">`AVAILABLE`</mark><mark style="color:blue;">, it means that the VPC has been created successfully;</mark> <mark style="color:blue;">`CREATE_FAILED`</mark> <mark style="color:blue;">means the VPC has been created failed. Any operations on the VPCs are not allowed while creating.</mark>
