SMS Global Coverage: United States

 Businesses operating an SMS messaging campaign in the United States of America (US) must adhere to specific industry norms and cell operator restrictions. The most critical industry guide you must follow is the CTIA Short Code Monitoring Handbook.

In the United States, all messaging is two-way, and message originators who use alphanumeric characters are not permitted. However, a diverse range of message originators are supported, including:

• Dedicated short code
• Long codes, or virtual mobile numbers
• Toll-free lines that accept text messages
• Text-enabled landline

Most US mobile providers support both toll-free and landline numbers.
