 # Prevent Phone Numbers from Being Flagged as Spam

This issue arises when carriers detect patterns that resemble spam behavior, such as high volumes of calls or messages. This can also result from end-user reporting the number as spam. The consequences include:

 1. **Monitor Call Patterns:** Regularly monitor call patterns to identify any unusual activity that may trigger spam filters. Avoid making a high volume of calls in a short period.
 2. **Use Caller ID:** Ensure that the customer’s caller ID is correctly set up and displays accurate information. This practice helps recipients recognize the caller and reduces the likelihood of being reported as spam (You can apply the Azure Communication process for Caller Name Delivery (CNAM) setup detailed [here](../telephony/how-to-manage-your-calling-identity.md)).
-3. **Obtain Consent:** Always obtain consent from recipients before making calls. This can be done through opt-in mechanisms where customers explicitly agree to receive calls from the customer’s business.

 4. **Provide Opt-Out Options:** Offer recipients an easy way to opt-out of receiving calls. This action can be done through automated systems or customer service representatives.
-5. **Maintain a Clean Contact List:** Regularly update and clean customer’s contact list to remove inactive or incorrect numbers. This practice reduces the chances of calling numbers that may report customer’s calls as spam.

 ## Register in FCR
 
-The [Free Caller Registry](https://www.freecallerregistry.com/fcr/) (FCR) serves as a system for organizations that conduct outbound calls to secure approval for their phone numbers, ensuring they are not incorrectly tagged as “Spam Likely” or “Scam” by mobile service providers. This initiative is backed by leading US vendors (TNS, FirstOrion and Hiya) who develop mechanisms to label incoming calls with a “Spam Likely” indicator. The registry holds significant importance for entities dependent on outbound calls for their business activities, as it helps to prevent their calls from being intercepted or wrongly marked as spam by carriers or external services. We recommend that customers initiate the process of phone number registration to mitigate this risk.

 Consider the following points when submitting the registration request:
 - It takes several days to get a response for updating all US-based carriers, to confirm or deny the request. Sometimes the best is also to contact the three providers who are supporting the platform:
   - First Orion : [email protected]
   - Hiya : [email protected]
   - TNS : [email protected]
-- In certain cases, customers may be asked by the platform vendors to set up an account as part of the application process.

 - Number registration will fix most of the “spam like” flags but it’s not a guarantee against any future flagging, in case customers do not comply with US regulations.
