With Klaviyo, you can verify one toll-free number, making it a trusted sending number for carriers. This in turn helps your SMS deliverability, increasing the number of messages that get delivered to your subscribers.
It will typically take 10–15 business days to be reviewed by the SMS Team and, if applicable, approved. In this article, we show you where to complete the form, what questions appear, and how to submit this request.
From December 15, 2020, to January 1, 2021, the approval process will be delayed. We apologize for any inconvenience!
Being Approved for Verification
You can only have one toll-free number per account. Further, not all toll-free numbers will be approved for verification. Any sender who seems to go against TCPA or CTIA guidelines will not be verified. In addition, it’s important to follow SMS best practices, including:
- Getting consent from recipients for SMS messaging
- Including opt-out language in every message
- Mentioning your brand by name in messages
- Providing high-quality content
- Keeping messages short and to the point
- Adhering to a set frequency
You should also avoid inappropriate and illegal content (e.g., SHAFT), high-risk financial services (loans, debt forgiveness, and credit repair), and deceptive marketing practices. These practices are frowned upon and will decrease your chances of having your toll-free number verified.
