In the age of digital communication, SMS marketing has become an increasingly popular tool for businesses seeking direct engagement with customers.

However, when it comes to using U.S. phone number lists for SMS marketing, many businesses wonder: is it legal? The answer is yes—but with strict conditions and compliance requirements. This article explores the legality, regulations, risks, and best practices involved in using U.S. phone number lists for SMS marketing.
The Legal Framework in the United States
In the United States, SMS marketing is governed primarily by the Telephone Consumer Protection Act (TCPA), which was passed in 1991 to protect consumers from unwanted and intrusive telemarketing calls and messages. The TCPA specifically restricts the use of automated telephone equipment, including SMS, for marketing purposes unless prior express consent is obtained from the recipient.
This means that even if you have access to a phone number list, you cannot legally send marketing text messages to those numbers unless each individual has clearly agreed to receive them. Consent must be explicit, not implied, and cannot be obtained through third-party data sellers without the consumer’s direct approval.
What Is Considered Legal Consent?

Clear disclosure that they will receive marketing messages.

Documentation of consent, including time, date, and method of opt-in.
Merely collecting a phone number during a purchase or website registration is not sufficient unless there is an accompanying clear and voluntary opt-in for text messaging.

Non-compliance with CTIA guidelines may result in blocked messages or revoked short codes, even if TCPA rules are technically followed.

Risks of Using Purchased or Scraped Lists
Some businesses are tempted to buy or scrape U.S. phone number lists from online sources. This practice is not only unethical but also highly risky. Here’s why:

Therefore, relying on purchased or non-opt-in lists is a major legal liability in the U.S. and should be strictly avoided.
