AWS announces End User Messaging Notify

Posted on: Mar 31, 2026

Businesses want to send one-time passcodes (OTPs) because they are often the easiest and fastest way for customers to verify who they are. However, businesses are often surprised when it takes weeks or months to get phone numbers, complete carrier registrations, and set up sender IDs. Today, AWS announces AWS End User Messaging Notify to change all of this. Within minutes, a developer can use phone numbers and sender IDs owned by AWS to power their OTP use case and start sending right away.

With Notify, you set up a configuration with your brand name, turn on SMS, voice, or both, and begin sending OTP messages to over 200 countries using ready-to-use templates. You can customize your brand name, code format, and how long a code stays valid. Every API call includes built-in SMS fraud protection through AWS End User Messaging SMS Protect at no extra cost, catching and blocking suspicious traffic before messages incur costs. Spend limits give you another layer of protection by pausing delivery if your account hits its set threshold.

AWS End User Messaging Notify is available in all AWS Regions where AWS End User Messaging is available.
