How OTP verification works

Customer selects the product
The buyer adds what they want to the cart on your Shopify store, exactly as they do today.
- 2
Clicks on checkout
They reach checkout and choose cash on delivery. Nothing about the page changes.
- 3
Verifies mobile number via OTP
COD King sends a one-time password over SMS or WhatsApp, and the buyer enters it to prove the number is theirs.

Order placed
Only verified orders are accepted. Everything else never becomes a parcel.

A seamless checkout experience
Verification is added inside the checkout you already have — without disrupting your store's design or the way a genuine buyer gets through it.
Before COD King
The buyer fills in checkout and places a cash-on-delivery order. Nothing confirms the number is real.
With COD King OTP
One verification step appears in your own store's styling. The code arrives in seconds.
After verification
The order is placed and moves on exactly as it did before — only now it belongs to a real buyer.
Advanced capabilities
Everything you can configure about how, where and when a buyer is asked to verify.
Country targeting
Ask for verification only in the countries you select, or in every country by default.
Blocked phone numbers
Blacklist specific numbers so they can never verify an order on your store.
SMS, WhatsApp or both
Choose which channel carries the one-time password, or send it over both.
Custom OTP branding
Your store name, your message, your logo on the verification your buyers see.
Choose what to verify
Trigger verification on every order, or only on the cash-on-delivery ones.
Prefilled shipping address
Fill the buyer's address in from their verified number. Available in India.
Auto-cancel timer
Set how long an order waits for confirmation. Unverified orders are cancelled automatically.
One-pass verification
A buyer who has already verified is not asked again across tabs or stores.
Multi-device optimised
Renders correctly on mobile, tablet and desktop checkout.
