How OTP verification works

  1. 1

    Customer selects the product

    The buyer adds what they want to the cart on your Shopify store, exactly as they do today.

  2. 2

    Clicks on checkout

    They reach checkout and choose cash on delivery. Nothing about the page changes.

  3. 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.

  4. 4

    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.

What Shopify merchants say

I was struggling with fake COD orders and losing time and money. After switching to COD King and enabling partial payment, the problem was solved. Customers now pay upfront, fake orders reduced, and operations run smoothly.
