Brevo requires you to register a Sender ID for each country where you send SMS messages. This helps protect your brand identity, ensures successful message delivery, prevents spoofing, supports local regulatory compliance, and enhances the credibility of your communications.

Before you start

• On Brevo, the Sender ID registration is mandatory for all countries receiving your SMS messages. This applies to both marketing and transactional messages.
• Understand and follow the SMS marketing regulations in your recipient country.
• Follow our best practices to ensure the best SMS deliverability.
• Sender ID registration may lead to additional costs in some countries (UAE, Romania, New Zealand, and USA for A2P10DLC and short code IDs).
• If you are registering a Sender ID for the USA or Canada, you also register your toll-free number as part of the same process. You will see two extra steps to confirm your website and your contact information.

❓ What is a Sender ID?

A Sender ID is the name or number shown as the SMS sender on recipients' devices that allows recipients to recognize the message source. It contains between 3 and 11 characters and is alphanumeric (brand name). Registering your Sender ID helps protect your brand, verify authenticity, and improve deliverability.

Each country requires a separate registered Sender ID, as formats and rules vary. This means SMS messages may show different Sender IDs based on recipient location:

📞 What is a toll-free number? (USA & Canada)

If you send SMS campaigns or transactional SMS to the United States 🇺🇸 or Canada 🇨🇦, you also need to register a toll-free number. A toll-free number is a telephone number with a distinct three-digit code that can be dialed or contacted by text from landlines or cell phones without charge for the caller. Toll-free numbers are usually used by businesses and customer services, making it easy for customers to connect with businesses without being charged for a long-distance call or SMS.

If you are based in the United States, you may be able to add an image to your SMS campaigns (MMS).
