# COD Verification on Checkout

Once customers add products to their cart, proceed to checkout and select cash on the delivery payment method, they are required to verify their mobile number through OTP. On click of the “Send OTP” button, the extension will send OTP to the billing address mobile number.

Once you get OTP, you have to add it in the text box and click the button to verify your mobile number. Else you can wait or use the “Resend OTP” button to send OTP again.
