Not All Businesses Can Use SMS - Here’s What You Need to Know
SMS is one of the best ways to reach your audience, but it’s also one of the most regulated. As texting grows in popularity, carriers are cracking down on spam and blocking messages from businesses in restricted categories.
That means if your business operates in certain industries, like those that are age-restricted or not approved by federal regulations - you may not be able to use SMS as a communication channel.
To stay compliant with carrier rules and protect message deliverability for all users, we follow strict guidelines. If your business falls into one of these restricted categories, your account may be subject to suspension or closure under our Acceptable Use Policy.
Forbidden Message Categories for SMS/MMS in USA/Canada*
Category | Examples | Notes |
High-risk financial services |
| "Third-party" means originating from any party other than the one which will service the loan. Examples of third-party loans could include: auto, mortgage, personal, etc.
First party loan content is acceptable if it is not promotional messaging, unless it is on an approved Short Code.
Businesses that solely operate in stocks, investing, or cryptocurrency are only permitted to send SMS traffic that is 2FA and/or transactional messaging. If there is a mixed use case where that is a partial aspect of the business, it may be approved based on the other use case content. |
Third-party lead generation services and marketing |
| Any third-party use cases are strictly forbidden. Consent must be obtained directly from end-users.
Political use case customers sending SMS messages are not able to use voter registration databases to collect consent and outreach end-users.
Any business with a terms of service or privacy policy that mentions sharing or selling consumer data/opt-in information is considered noncompliant. |
Debt collection or forgiveness |
| "Third-party" means originating from any party other than the one who is owed the debt. For example, a hospital could send messages regarding bills for its own patients, assuming they provided opt-in to receive that messaging.
While third party debt collection is not permitted, a debt collection business that has direct consent from end-users to send related content may do so.
Debt consolidation, debt reduction, and credit repair programs are prohibited regardless if there is first-party consent. |
“Get rich quick” schemes |
| Use cases in this category pertain to minimal effort for maximum and/or guaranteed financial gains. These categories in the telecoms industry produce high consumer complaints and are not permissible on carrier routes.
