1. Compliance and Regulations
   Sending SMS in the USA requires compliance with several regulations to protect consumer privacy and prevent spam. Key regulations include:
   • Telephone Consumer Protection Act (TCPA): Requires businesses to obtain explicit consent from consumers before sending SMS messages. This includes clear opt-in mechanisms and honoring opt-out requests.

2. Types of SMS Numbers
   When sending SMS in the USA, businesses can choose from different types of numbers:
   • Short Codes: Typically, 5–6-digit numbers used for high-volume messaging campaigns. They are easy to remember and ideal for marketing purposes. You can read more about the same in our guide on SMS short codes.
   • Long Codes: Standard 10-digit phone numbers used for person-to-person communication and low-volume messaging. They are more personal and can handle two-way communication.
   • Toll-Free Numbers: 1-800 numbers that support both voice and SMS, offering a versatile option for customer service and support.

3. Content Restrictions

Different industries also need to comply with specific content regulations. For example: A2P 10DLC for political campaigns.

4. Technical Considerations
   Effective SMS campaigns require attention to technical details:
   • Character Limit: Standard SMS messages are limited to 160 characters. Messages exceeding this limit will be split into multiple parts and may incur additional charges.

   • Unicode Support: Essential for messages containing special characters or emojis to ensure correct display across all devices.
     
   • Message Segmentation: Long messages are automatically segmented and reassembled on the recipient’s device, but this can affect message costs and readability.
     
   • Opt-Out Mechanism: Mandatory inclusion of opt-out instructions (e.g., "Reply STOP to unsubscribe") to comply with regulations and improve customer satisfaction.
     
   • Rate Limits: Carriers may impose rate limits on the number of messages sent per second to prevent spamming and ensure network reliability.
     
   • Throttling: Managing the rate at which messages are sent to avoid exceeding carrier limits and to ensure consistent delivery.
     
   • Sender ID: Customizable sender IDs (where supported) can improve brand recognition and engagement but must comply with carrier and regulatory requirements. You can read more about the same in our article on A2P 10DLC.  
     
   • Message Templates: Pre-approved message templates can streamline the sending process and ensure compliance with content guidelines. Although, you can enable use cases like SMS verification without an approved content template or 10DLC.
