Understanding 10DLC, Short Codes, and Toll-Free Numbers for SMS in North America
Businesses looking to engage with customers in North America through SMS have three main options: 10DLC (10-digit long codes), short codes, and toll-free numbers. Each option serves unique purposes and comes with its own set of advantages.
1. 10DLC (10-Digit Long Codes)
10DLC is the latest standard for application-to-person (A2P) messaging in North America. Designed for businesses, it allows companies to send high-volume, compliant text messages using a standard 10-digit phone number.
Advantages:
• Ideal for personalised, two-way communication.
• Cost-effective for businesses with moderate messaging volumes.
• Local appearance, which can enhance trust and engagement with recipients.
Considerations:
• Requires registration to comply with carrier regulations.
• Subject to carrier filtering if not used properly.
2. Short Codes
Short codes are 5- to 6-digit numbers widely used for high-volume messaging campaigns, such as promotions, alerts, and two-factor authentication.
Advantages:
• Supports massive throughput, making them perfect for large-scale campaigns.
• Easy to remember, enhancing customer engagement.
Considerations:
• More expensive to lease and operate.
• Dedicated short codes require registration and approval, which can take time.
3. Toll-Free Numbers
Toll-free numbers (e.g., starting with 800, 888) are another popular option for business messaging. Traditionally used for voice calls, these numbers now support SMS for both one-way and two-way communication.
Advantages:
• National presence, appealing to businesses with a wide customer base.
• Cost-effective for medium to high message volumes.
Considerations:
• Slightly less personal compared to local 10DLC numbers.
• Requires proper setup to ensure deliverability.
Which Option is Right for Your Business?
Choosing the best option depends on your messaging needs. 10DLC is great for businesses wanting a local touch, short codes excel for high-volume campaigns, and toll-free numbers provide a balance between national reach and affordability.
Regardless of your choice, compliance with carrier regulations and a clear understanding of your use case are critical to ensuring successful SMS campaigns.
