A2P SMS means ‘application-to-person’
SMS, so it’s the Delivery of a SMS from a software to a person. Usually the software is an application which is operated through a company. This application sends automated SMS to the telephone of the end-user, which can not only be customers but also employees of your company. Examples of these applications are notifications of a credit card company about sales figures, booking confirmations, reminders for appointments
of doctors and workshops or security codes for the login on a website or by a bank, right before the transaction is completed (2FA
). One can therefore also call A2P SMS a professional SMS.
In contrast, there is the P2P SMS. The SMS will not be sent by an application, but instead from a telephone. These can be private SMS and also not automatically processed business SMS, for example appointment reminders manually sent by the doctor’s assistant.
