Frequently asked questions about transactional SMS
To send any SMS message as a business, including transactional SMS, you must first check your target market’s local laws and SMS regulations. The requirements may vary depending on the market, but you may need to have a registered business number and sender ID. You can find more details in our guide on getting started with SMS.
Although some might categorize SMS OTP as transactional, we consider it a specialized form of transactional SMS with a focused purpose. It provides an additional layer of security for businesses, allowing them to send passwords or other codes to an end-user’s mobile device. These are usually used in online banking, account login, and other verification and authentication processes.
The main difference between promotional and transactional SMS messages is their purpose. Promotional SMS is used with commercial (promotional) intent, while transactional SMS is non-promotional. You can learn more about the differences between promotional and transactional SMS here.
