# @ohos.enterprise.deviceInfo（设备信息管理）(系统接口)

本模块提供企业设备信息管理能力，包括获取设备序列号等。

> **说明：**
>
> 本模块首批接口从API version 10开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。
>
> 本模块接口仅可在Stage模型下使用。
>
> 本模块接口仅对[设备管理应用](../../mdm/mdm-kit-guide.md#功能介绍)开放，需将[设备管理应用激活](js-apis-enterprise-adminManager-sys.md#adminmanagerenableadmin)后调用，实现相应功能。
> 
> 当前页面仅包含本模块的系统接口，其他公开接口参见。其他公开接口参见[@ohos.enterprise.deviceInfo](js-apis-enterprise-deviceInfo.md)。
