Text Number Registration
Why do I have to register my text numbers?
Mobile carriers require registration for all mass text messaging to prevent fraud and spam. Registration establishes legitimacy for your organization and messages, helping ensure reliable delivery while reducing unwanted messages across the network. Text-Em-All supports these carrier efforts because they align with our commitment to responsible messaging.
Who needs to register?
Anyone using Text-Em-All or similar services must register to send text messages. Registration applies to both toll-free numbers and local landline numbers. Voice-only messaging does not require registration.
| Message Type | Registration Required | Notes |
|---|---|---|
| Text messages (SMS/MMS) | Yes | All toll-free and local numbers |
| Voice messages only | No | Registration not needed |
What do I need to register?
Registration requirements depend on your specific use case, but most organizations need documentation of their opt-in process, an online presence, and business information if applicable.
Required documentation
- Opt-in process examples: Screenshots showing how recipients provide phone numbers and consent to receive messages
- Online presence: Website, social media page, or other digital presence that carriers can verify
- Business tax ID (EIN): Required for businesses registering local numbers. Non-business use cases can register without a tax ID
Does registration cost anything?
Text-Em-All does not charge any registration fees to customers. There are no registration fees and no per-message fees passed through to you, even though carriers charge these fees to messaging providers.
How long does registration take?
Registration timelines vary by number type but are typically completed within a few business days.
| Number Type | Typical Timeline | Notes |
|---|---|---|
| Toll-free numbers | 1-4 business days | Standard processing time |
| Local numbers | Less than 1 business day | Most registrations process same day |
Important: Your text number cannot send messages until registration is complete.
What are the message limits after registration?
Message delivery speed and daily caps are set by individual carriers based on your registered use case and vetting score. Each carrier has different restrictions and capabilities.
Carrier-specific limits
| Carrier | Limit Type | Range |
|---|---|---|
| T-Mobile | Daily message cap | 1,000 to 200,000 messages per day |
| AT&T | Messages per minute | 15 to 4,500 messages per minute |
Understanding message segments
Messages are counted in 160-character segments. A 320-character message equals 2 segments.
Example scenarios:
Scenario 1: You send a 300-character message to 100 contacts. This equals 2 segments × 100 contacts = 200 total messages. AT&T recipients will receive messages at the slower delivery speed (15 messages/minute), while other carriers deliver normally.
Scenario 2: You send a 100-character message to 2,500 contacts. This equals 1 segment × 2,500 contacts = 2,500 total messages. You would be prompted to register as a high-volume sender because this exceeds T-Mobile's base daily cap.
Need higher volume? If you plan to send more than 4,000 text messages in a single day, contact our support team for help with high-volume registration.
Note: Text messages are counted in 160-character segments, so a 320-character message counts as 2 segments.
Can I use my own local number?
Yes, you can text-enable your existing landline phone number through Text-Em-All. Mobile phone lines cannot be used for mass texting due to carrier restrictions.
How to register your landline
- Complete the Text-Em-All Letter of Authorization
- Email the completed form to support@text-em-all.com
- Our team will work with carriers to text-enable your number
Important limitations:
- Only landline numbers work for mass texting
- Mobile phone lines are not eligible
- A number can only be used on one platform at a time
- Using your personal mobile number would prevent it from working in standard messaging apps like iMessage
