Understanding SMS Short Codes, Long Codes, and 10DLC for Business Compliance

Introduction

In the evolving landscape of business communication, understanding the types of SMS messaging is crucial for compliance and effective outreach. This article delves into the differences between SMS short codes, long codes, and 10DLC, particularly in the context of compliance with U.S. regulations.

What Are SMS Short Codes?

SMS short codes are 5- to 6-digit numbers specifically designed for high-volume messaging. They are commonly used for marketing campaigns, alerts, and promotions. Here are some key points about short codes:

• High Throughput: Short codes can send a large volume of messages quickly, making them ideal for campaigns.
• Brand Recognition: They are easily recognizable by consumers and can enhance brand visibility.
• Cost: Typically, short codes involve higher costs due to leasing fees and setup.

What Are SMS Long Codes?

Long codes are standard 10-digit phone numbers that can be used for both person-to-person (P2P) and application-to-person (A2P) messaging. They are often used for customer service and two-way conversations. Here’s what to know:

• Versatility: Long codes are suitable for conversational messaging and can handle lower message volumes.
• Cost-Effective: They usually come with lower costs compared to short codes, making them accessible for small businesses.
• Compliance Requirements: Long codes still require adherence to regulations, including obtaining consent and honoring opt-outs.

What Is 10DLC?

10DLC (10-Digit Long Code) is a relatively new standard in the U.S. designed specifically for A2P messaging. It provides businesses with a way to send messages using standard 10-digit numbers while ensuring compliance with carrier regulations. Here are the essentials:

• Registration Requirement: Businesses must register their brand and campaigns with carriers through The Campaign Registry (TCR) to use 10DLC effectively.
• Improved Deliverability: Proper registration enhances message deliverability and reduces the risk of being filtered as spam.
• Use-Case Alignment: Messages must align with the registered use case, ensuring that the content matches the intended purpose of the campaign.

Key Differences

Understanding the differences between these messaging types can help you choose the right one for your business needs:

Compliance Considerations

Regardless of the messaging type you choose, compliance is paramount. Here are some key compliance considerations:

1. Obtain Consent: Always get clear consent before sending marketing messages. Maintain records of how and when consent was obtained.
2. Honor Opt-Outs: Implement a straightforward opt-out process. Common keywords include STOP, UNSUBSCRIBE, and CANCEL. Process these requests promptly to remain compliant.
3. Identify Your Business: Always include your business name in messages to ensure transparency.
4. Respect Quiet Hours: Be mindful of sending messages during appropriate hours to respect consumer preferences.
5. Suppress Lists: Maintain a suppression list to avoid contacting numbers that have opted out or are on Do Not Call lists.

Conclusion

Choosing between SMS short codes, long codes, and 10DLC depends on your business's messaging needs and compliance requirements. By understanding these options and adhering to compliance guidelines, you can ensure effective and lawful communication with your audience.
