10DLC Compliance Mistakes That Cost Businesses Thousands
A single 10DLC compliance mistake can cost your business thousands of dollars in fines, blocked messages, and lost revenue. With carriers like T-Mobile now issuing fines of $10,000+ for persistent violations, compliance isn't just a best practice—it's business-critical.
The stakes have never been higher. In 2024 alone, businesses paid over $50 million in carrier fines for 10DLC violations, with most penalties completely avoidable through proper setup and ongoing compliance management.

The 10 Most Expensive 10DLC Mistakes
Mistake #1: Operating Without Registration
The Error: Continuing to send business messages from unregistered long codes after 10DLC became mandatory.
Why It Happens:
- • Businesses unaware of 10DLC requirements
- • Assumption that low message volumes are exempt
- • Confusion about registration timeline
- • Providers not educating customers about compliance
The Cost:
- • Direct: $0.003-0.01 per message in carrier fees (10x normal)
- • Indirect: 60-80% message blocking, customer complaints
- • Example: 10,000 messages/month = $3,600 annual penalty
The Fix:
Register immediately with The Campaign Registry through a qualified CSP. Most registrations complete within 2-3 business days.
Mistake #2: Wrong Campaign Classification
The Error: Registering marketing campaigns as "informational" or mixing content types inappropriately.
Real Example:
ABC Fitness registered as "appointment reminders" but sent:
- • "Don't miss our New Year special - 50% off memberships!"
- • "Last chance for our summer body bootcamp!"
- • Mixed with legitimate appointment confirmations
Why It Happens:
- • Desire to avoid marketing campaign restrictions
- • Misunderstanding of campaign types
- • Evolution of messaging strategy after registration
- • Poor initial campaign planning
The Cost:
- • Campaign suspension: Immediate message blocking
- • Fines: $1,000-5,000 per violation
- • Re-registration: Additional fees and delays
- • Lost campaigns: Months of blocked promotional messages
The Fix:
- • Register separate campaigns for different message types
- • Use "Mixed Marketing" category when combining content types
- • Review campaign classification with compliance expert
- • Update registrations when messaging strategy changes
Mistake #3: Inadequate Consent Management
The Error: Sending messages to recipients who haven't provided proper opt-in consent for text messaging.
Common Scenarios:
- • Assuming email subscribers want text messages
- • Using purchased phone number lists
- • Adding customers without explicit SMS consent
- • Inadequate opt-in language or process
Real Example:
Premier Auto used email list for text promotions:
- • Sent 25,000 texts to email subscribers
- • 847 recipients filed spam complaints
- • Carrier investigation revealed no SMS consent
- • $15,000 fine plus campaign suspension
The Cost:
- • Spam complaints: $500-2,000 per verified complaint
- • Campaign suspension: All messaging blocked
- • Legal risk: Potential TCPA violations ($500-1,500 per message)
- • Reputation damage: Carrier trust score reduction
The Fix:
- • Implement explicit SMS opt-in processes
- • Document consent with timestamps and source
- • Use double opt-in for marketing campaigns
- • Regular consent audits and list cleaning
Mistake #4: SHAFT Content Violations
The Error: Sending prohibited content (Sex, Hate, Alcohol, Firearms, Tobacco) through registered campaigns.
Examples of Violations:
- • Wine shop sending tasting event invitations
- • Gun store sending sale notifications
- • Dating app sending promotional messages
- • Political messages with divisive content
Why It Happens:
- • Lack of awareness about SHAFT restrictions
- • Broad interpretation of business categories
- • Third-party content that violates policies
- • Seasonal campaigns that cross into prohibited areas
The Cost:
- • Immediate suspension: All campaigns blocked instantly
- • Heavy fines: $5,000-25,000 per campaign
- • Permanent impact: Difficulty getting future campaigns approved
- • Business disruption: Complete loss of text messaging channel
The Fix:
- • Review all content for SHAFT compliance before sending
- • Train staff on prohibited content categories
- • Use content approval workflows
- • Regular audit of message templates and campaigns
Mistake #5: Using Generic Link Shorteners
The Error: Including bit.ly, TinyURL, or other generic shortened links in business messages.
Why It's Problematic:
- • Carriers flag generic shorteners as potential spam
- • High association with phishing and fraud
- • Reduced message deliverability
- • Potential campaign suspension
Real Example:
Local Restaurant included bit.ly links in promotional messages:
- • Message delivery dropped to 35%
- • Customers complained about missing promotional offers
- • Lost $8,000 in expected promotional revenue
- • Campaign marked as "high risk" by carriers
The Cost:
- • Reduced deliverability: 30-50% delivery rate drop
- • Lost revenue: Missed promotional opportunities
- • Campaign penalties: Additional scrutiny and restrictions
- • Customer complaints: Poor experience and lost trust
The Fix:
- • Use branded short domains (go.yourbusiness.com)
- • Carrier-approved shortening services
- • Full URLs when space permits
- • Link reputation monitoring
Prevention Strategies

The Bottom Line
10DLC compliance mistakes are expensive, but they're also preventable. The key is understanding the requirements, choosing the right provider, and implementing proper processes from the start.
While the cost of compliance might seem high initially, it's nothing compared to the cost of violations. A $200 registration fee is a small price to pay to avoid $47,000 in fines and lost revenue.
