10DLC Registration (US)

10DLC (10-Digit Long Code) is the industry standard for business SMS messaging in the United States. Registration is required to send A2P (Application-to-Person) messages from local phone numbers.

What is 10DLC?

10DLC refers to standard 10-digit local phone numbers (like 555-123-4567) used for business messaging. Before 10DLC, businesses could send SMS from any local number, but this led to spam and carrier filtering issues.

Now, all businesses must register with The Campaign Registry (TCR) to:

• Verify their business identity
• Describe their messaging use cases
• Get carrier approval for their campaigns

Why Register?

Severe carrier filtering	High deliverability
Messages may be blocked	Carrier-approved sending
Low throughput limits	Higher message volume
Risk of number suspension	Protected sender reputation

4. Use your real business name - not abbreviations
5. Keep samples realistic - use actual message templates
