Documentation

Mobile number verification is an OTP (One time password) based security addon for Classified Listing Pro. This addon helps verify a real user by sending an OTP verification code during registration, login, and contact form submissions. Sometimes spammers added listings and tricks the buyer.

If you use mobile verification, you can quickly identify the fraudulent guy. Also, you can protect spam listing. Furthermore, it removes the possibility of users registering with fake Mobile Numbers by enabling OTP Verification. The OTP Verification addon also checks if the Mobile Number already exists.

This Mobile Number Verification addon is powered by Twilio for sending SMS. We support OTP Verification worldwide. It is available for both free and pro plugins.

  • 1. These days, verifying a user’s mobile number upon registration is a requirement. Having your own SMTP/SMS gateway using our addon is no longer essential. You may send OTP SMS using our gateways.
  • 2. SMS Coverage globally
