What is compliance for text messages?

Compliance for text messages, also called SMS compliance, is an industry term for following messaging regulations and guidelines. You achieve SMS compliance by adhering to these rules.

SMS compliance is the act of following messaging regulations and guidelines; also called compliance for text messages

Why should you achieve SMS compliance?

Some SMS regulations apply to all businesses, like the Telephone Consumer Protection Act (TCPA). Several regulations only apply if you do business in certain areas, like the California Consumer Privacy Act (CCPA) or the European Union’s General Data Protection Regulation (GDPR). In other cases, professional organizations recommend compliance with their guidelines, like SOC 2, but it’s not a legal requirement.

Whether it’s required by law or recommended by industry bodies, achieving compliance with all SMS regulations and requirements helps your business better protect your customers’ data, privacy, and well-being so you can build trust.

Common SMS compliance standards

Here are the rules, regulations, and standards most likely to apply to your business:

List of business texting regulations, including the Telephone Consumer Protection Act (TCPA) and General Data Protection Regulation (GDPR)

California Consumer Privacy Act (CCPA)/California Privacy Rights Act (CPRA)

Signed into law in 2018, the CCPA created consumer privacy rights and business requirements for the collection and sale of consumer data. The CPRA, which became operative in 2023, amends and expands the CCPA. If your business messages any Californian customers, these regulations apply to you.

General Data Protection Regulation (GDPR)

The GDPR was passed in 2016 and implemented in 2018. GDPR compliance is mandatory if you message customers in the EU. It requires you to protect EU citizen data, taking measures to prevent data theft and protect user privacy. Even if you don’t have customers within the EU, complying with this standard can help you improve data security.

The Health Insurance Portability and Accountability Act (HIPAA)

HIPAA affects all businesses that work with patients or patient data, mandating that you protect sensitive patient data at all costs. HIPAA-compliant texting means ensuring that you don’t text patient test results, diagnoses, or any other sensitive information. It also involves developing privacy policies and practices to ensure you don’t share electronic protected health information (ePHI), and anonymizing any health-related data you intend to use for analytics.

Service Organization Control 2 (SOC 2)

Launched in 2010, SOC 2 is a set of standards developed by the Association of International Certified Professional Accountants (AICPA). SOC 2 reports evaluate your data security. Complying with SOC 2 isn’t required by law, but recommended and even expected if your business works with customer data. Achieving text messaging compliance with SOC 2 requires you to ensure that your data processes and workflows are well-documented and secure. To achieve official compliance, you must have a third-party provider review and evaluate your data management. You can choose between two types of SOC 2 reports—a simple Type 1 report or a thorough Type 2 report.

The Telephone Consumer Protection Act (TCPA) 

The TCPA is one of the most well-known regulations in the business SMS industry, and it applies to all businesses that text their customers. It mandates that you get consent from your customers before you text them, and make it easy for them to opt out. It also requires you to be transparent when promoting your SMS services. TCPA compliance is a legal requirement.

10 Digit Long Code (10DLC) registration

10DLC registration applies to all companies that text customers through 10-digit long codes of any kind. To use these standard 10-digit phone numbers, you must register with telecom carriers. Registering helps carriers protect text messaging as a trustworthy channel while allowing you to contact larger lists of customers. Your business texting service should allow you to register through their platform, and support you during the process.

SMS compliance terms

When we talk about achieving compliance, we use specific industry terms. We’ve gathered up the most common terms here to help you better navigate SMS compliance articles:

A2P messaging

Application-to-person messaging (A2P messaging) includes any messages sent from an application. Carriers in the United States and Canada define all messages that pass through messaging platforms like Heymarket as A2P. This includes one-on-one SMS customer service chats as well as automated appointment reminders, order notifications, and after-hours replies.

Electronic protected health information (ePHI)

ePHI refers to any information that may be used to identify a patient or that refers to the status of a patient’s health. This includes data like test results, diagnoses, care instructions, visit recaps, and more. Under HIPAA, it is illegal to text any of this information.


Opting in means giving consent to participate in something. In business text messaging, customers have to opt in before you can text them. You can ask customers to text a keyword to your SMS number or click a box on a web form. Either option allows you to capture their opt-in.


Opting out means withdrawing consent to participate in something. In business text messaging, customers must be able to opt out of your SMS services at any time by texting a keyword. Your business text messaging platform should be able to immediately capture the opt-out request and unsubscribe customers.

P2P messaging

Peer-to-peer messaging (P2P messaging) refers to messages sent between two consumers. This would include the texts you recently sent to friends and family. Again, carriers in the United States and Canada consider all messages that pass through messaging application platforms (like Heymarket!) to be A2P.


Ten-digit long codes (10DLC) are typical phone numbers you see on your phone every day; they have 10 digits and a local area code. (415-555-0101 is a 10DLC number.) Recently, carriers have upgraded businesses’ 10DLC capabilities, allowing them to send a higher volume of messages to customers. Because 10DLCs are versatile, they are expected to become the industry standard.

Key players in compliance for text messages

Several organizations create, manage, and (in some cases) enforce SMS compliance standards. Here are the ones you’ll hear about most often:

American Institute of Certified Public Accountants (AICPA)

This national professional organization develops ethical standards for accountants as well as U.S. auditing standards for service organizations. Most recently, the AICPA created SOC 2 guidelines.

Cellular Telecommunications and Internet Association (CTIA)

This organization represents and advocates for the wireless telecommunications industry. It also offers guidance to businesses that text. For example, the CTIA provides advice about how to get opt-ins from customers.

Federal Communications Commission (FCC)

The FCC is a government organization that regulates communications in the U.S and the telecommunications industry. It creates and enforces laws, most notably the TCPA.

The U.S. Department of Health and Human Services (HHS)

The HHS is a government organization that oversees the health of Americans in the U.S. Their Office for Civil Rights oversees and enforces HIPAA.

The Campaign Registry (TCR)

TCR is a third-party business that manages the A2P 10DLC messaging registration process. It collaborates with brands, carriers, and business texting platforms to ensure that companies texting consumers register their 10DLC numbers.
