An Alphanumeric Sender ID is a customized text string that appears as the sender of an SMS message, instead of a phone number. This sender ID can include letters, numbers, or a combination of both and is commonly used by businesses to display a branded name, such as the company name or a service identifier, to recipients of the message. It is a convenient way to make SMS communications more recognizable and professional.

Alphanumeric Sender ID In U.S.

Alphanumeric sender IDs, using brand names or short phrases instead of phone numbers, are not supported in the United States. Instead, SMS messages sent within the U.S. must originate from a numeric short code or a pre-registered 10DLC long code.

What can I put as an Alphanumeric Sender ID? 

Countries that support Alphanumeric Sender ID, typically offer:

• Customized sender name that represents the business or service
• Letters, numbers, or a mix of both to create a unique ID
• There is a limit on the number of characters (usually 11-16 characters depending on the country and network carrier)
• Support for transactional and promotional messages with a recognizable sender name

• Compliance with regional rules and regulations for sender ID usage

   

Why Use a Sender ID?

An Alphanumeric Sender ID is crucial for businesses and SMS Marketing to build brand recognition and enhance trustworthiness in SMS communications. It makes it easier for recipients to identify the source of the message, reducing the likelihood of it being mistaken for spam. Additionally, using a custom sender ID improves engagement as customers are more likely to open and respond to messages from a known or trusted sender. It also ensures that businesses can maintain a professional appearance in their messaging efforts.
