What is SMS Sender ID?
An SMS Sender ID is the name or number that appears as the sender when recipients receive your SMS messages. Instead of displaying a random phone number, a well-chosen Sender ID shows your brand name or company identifier, making your messages instantly recognizable and trustworthy. At Text.lk SMS Gateway Sri Lanka, we know that a good Sender ID goes beyond just a name.
Why your Sender ID is important?

12 Essential Tips for Choosing Your SMS Sender ID
1. Keep It Short and Memorable
Character Limit: Your Sender ID must be 11 characters or less for alphanumeric IDs.
Best Practice: Aim for 6-8 characters to ensure easy readability and memorability.
Examples:
- Instead of “SuperMarketChain” → Use “SuperMkt” or “SuprMart”
- Instead of “TechSolutions” → Use “TechSol” or “TechSup”
2. Make It Brand-Aligned
Your Sender ID should directly reflect your brand name or be easily associated with your business. This creates instant recognition and builds trust.
Good Examples:
- “Amazon” for Amazon Products
- “PayPal” for PayPal Payments
- “FedEx” for FedEx Deliveries
- “TextLK” for Text.lk SMS Gateway Sri Lanka
3. Avoid Numbers and Special Characters
Character Rules:
- ✅ Allowed: A-Z, a-z, 0-9, spaces, hyphens (-), underscores (_)
- ❌ Avoid: Special characters (#, @, %, $, etc.)
- ❌ Don’t use: Numbers-only Sender IDs for branding purposes
Why: Numbers and special characters can trigger spam filters and make your messages appear unprofessional.
4. Think Long-Term and Scalable
Choose a Sender ID that can grow with your business. Avoid being too specific if you plan to expand services.
Example: Instead of “FlowerShop” (limiting), use “BloomCo” (allows for garden supplies, events, etc.)
5. Research Trademark and Usage Rights
Before finalizing your Sender ID, ensure it’s not trademarked or used by competitors:
- Check trademark databases
- Search existing business names
- Verify domain availability
- Review competitor Sender IDs in your industry
6. Avoid Generic Terms
Don’t use generic terms like “Info,” “Support,” or “Admin” as these are often flagged as spam.
Instead use:
- Your actual business name
- Recognizable brand abbreviations
- Service-specific identifiers tied to your brand
7. Consider Your Message Type
Different message types may require different Sender ID approaches:
- OTP/Security: Use your main brand name for trust
- Marketing: Use campaign-specific but brand-related IDs
- Notifications: Use service-specific identifiers
8. Test for Pronunciation and Spelling
Your Sender ID should be easy to:
- Pronounce when spoken aloud
- Spell without confusion
- Remember after seeing it once
Avoid: Complex abbreviations or unclear letter combinations.
9. Follow local rules and guidelines
Different countries have varying regulations for Sender IDs:
For Sri Lanka specifically:
- Registration required for all alphanumeric Sender IDs
- Must be 3-11 characters
- Content must include your brand name
- Separate registrations needed for OTP vs. Marketing messages
10. Use Consistent Branding
Align your Sender ID with your other digital assets:
- Match your social media handles when possible
- Align with your domain name style
- Ensure consistency across all customer touchpoints
11. Avoid Double Letters
Why: Double letters increase typo chances and can cause delivery issues.
Examples to avoid:
- “BookStore” → Use “BookShop”
- “FoodDelivery” → Use “FoodDel”
12. Plan for Multiple Sender IDs
Consider registering multiple Sender IDs for different purposes:
- Primary brand for general communications
