# Create a Custom STOP Keyword in MobileConnect

Create a custom STOP keyword for Marketing Cloud Engagement. This topic contains important legal information.

Marketing Cloud Engagement adds more mandatory text to STOP messages sent from short and long codes based in the United States. This text ensures that STOP messages comply with MMA/CTIA regulations. Short and long codes based outside of the United States do not include this text in STOP messages. STOP messages should not exceed 160 characters to prevent more messages from sending to unsubscribed contacts. If the message includes more than 160 characters, that message splits into two separate sends. The sending of multiple messages does not align with the mobile best practice of acknowledging an unsubscribe request with a single message. Long company names and AMPscript usage could also increase the character count beyond 160 characters. Ensure that you test your STOP messages and make them align with applicable best practices.

1. In the app switcher, hover over your name and click **Setup**.
2. Search for MobileConnect.
3. Select the short or long code.
4. Click **Create STOP Keyword**. If there’s an existing STOP keyword, click **Edit** next to Account STOP.
5. Click **Create**.
6. Enter the STOP keyword.
7. Enter the message for users who request assistance.
8. Select more options, if necessary.
    1. Do not send any unsubscribe response by selecting **Suppress Response Message**. MobileConnect unsubscribes the contact and executes any AMPscript included in the STOP message field. The contact does not receive a message in response to the unsubscribe request. This option is for users outside the United States with a private short or long code.
9. Save the keyword.
