What is Disposable Phone Number?

What is Disposable Phone Number

Disposable phone number is an online temporary virtual phone number allowing users to receive SMS messages. This virtual phone number is shared among all users, and usually, it is used by many to receive the account verification OTP for their temporary access. It’s a fake identity, and it will damage the merchant services and cause huge losses. For example, a perpetrator could bypass your phone verification process and sign up with multiple accounts to exploit your services.

In FraudLabs Pro, we cover this for you. Our algorithm will regularly scout the web and glean the active disposable phone numbers from various sources for fraud verification. And, at present, we have a list of thousands of disposable phone numbers currently being used worldwide. If you are currently a Medium Plan (or higher plan) subscriber, your orders had already been protected from the disposable phone number exploitation. You may now view the disposable phone number status of your order in our merchant area. Below is the screenshot of the transaction:

You can also create your own validation rule to reject the order if the disposable phone number was detected. Below is the screenshot of the disposable phone number rule:

If you are using our REST API for fraud screening, you may check for is_disposable_phone_number field in the response message to determine if the user phone is a disposable phone number. Below please find an example of the response message:

We have observed an increased use of disposable phone numbers to circumvent the verification process for account registration, checkout and so on. Hence, it’s important for you as the merchant to be able to detect and block them. If you are not a Medium plan user, you may upgrade your plan at your merchant area to enable this feature.
