## Mandatory compliance verification

As of January 31, 2024, new compliance regulations for toll-free numbers will be enforced. These regulations are designed to help the industry combat spam, and provide a better experience for all users.

They will also help to reduce the likelihood of false-positive filtering, and wrongful spam blocks, increasing the overall deliverability of your messages.

### What's changing?

Currently, you and/or your customers can send messages through pending toll-free phone numbers as long as they meet existing industry-wide sending limits.

Now, all toll-free messaging services in the U.S. and Canada must complete a mandatory compliance verification process.

Only fully verified toll-free phone numbers will be eligible to send messages. 

Blocked messages will return one of the following errors:

* **Spam reject**: `Error Code 110 EC_MESSAGE_FILTERED.`
* **Toll-free number not verified:**`104 EC_SENDER_UNREGISTERED`.

{% hint style="warning" %}
Blocked messages are still subject to messaging fees. 
{% endhint %}

### What do I need to do?

If you have U.S. or Canadian toll-free numbers that are in use and unverified, you will need to complete verification prior to January 31st, 2024 to avoid blockage.

### How do I complete verification?
