Amazon OTP stands for "one-time password" and is a security feature used by Amazon to protect packages and accounts from unauthorized access. When an OTP is required for a delivery, Amazon sends a six-digit, numeric OTP to the registered email address after the item is shipped. The OTP can also be found by selecting "Track Package" beside the order in "Your Orders". The OTP is valid until the end of the delivery day and should be read to the driver when the package is received. If the recipient is not available to receive the package, the OTP can be shared with someone else to receive the package, but it is not recommended to share it with an unknown person.
Amazon Pinpoint, a service provided by Amazon Web Services, also includes an OTP management feature that generates and verifies unique one-time passwords for users of an application or service. This feature can be used to generate new OTP codes and send them to recipients as SMS text messages. Applications can then call the Amazon Pinpoint API to validate that the OTP code the recipient entered is valid.
It is important to note that scammers may also use OTPs to try to gain access to Amazon accounts. However, Amazon will only send an OTP text message, also referred to as two-step verification (2SV), if the recipient is trying to log into their Amazon account from a new device. If an OTP text is received out of the blue, it may be a scam and should be treated with suspicion.
