# The “This email address cannot be registered. Check the details with the administrator at your company. ” error is displayed

When registering a new Free Plan account, the “このメールアドレスは登録できません。貴社管理者までご確認ください。(This email address cannot be registered. Check the details with the administrator at your company.) ” error may be displayed.

[![EmailErr1](https://help.cloudsign.jp/hs-fs/hubfs/EmailErr1.png?width=670&height=327&name=EmailErr1.png)](https://help.cloudsign.jp/hubfs/EmailErr1.png?hsLang=en)

 

### **Cause**

The domain of the email address being used to register a new account may be restricted from registering a new Free Plan account due to the [Account registration restriction function](https://help.cloudsign.jp/en/articles/435347?hsLang=en).

 

### **Solution**

Check that your company is subscribed to the Paid plan.

If you are, ask your company’s “team administrator” to [Add a member](https://help.cloudsign.jp/ja/articles/385226?hsLang=en).

 

If you are unable to check which plan you are subscribed to, please send an inquiry using the Chat support at the bottom right of the CloudSign website.

 

#### **Precautions**

- If you have received a document with an [High-level authentication request function](https://help.cloudsign.jp/ja/articles/4669200?hsLang=en), the same error is displayed as when the specified recipient does not have an account and their email address has a domain that is restricted from registering an account.
