Email checks
Detect temp domains, typo domains, mailbox issues, and risky free-provider patterns before order creation.
Shopify COD protection
CODProof
Check cash-on-delivery orders before they become Shopify orders.
Built for COD stores
Reduce fake orders without slowing real buyers.
CODProof adds a storefront COD form with email checks, phone checks, OTP rules, delivery options, and merchant-managed blocklists.
Phone checks
Catch invalid length, country mismatch, placeholder patterns, and mobile-number rule mismatches.
Verification rules
Require OTP only when your settings say it is needed, such as larger order values or risk signals.
Delivery accuracy
Use Shopify delivery rates or app delivery rules so the COD form mirrors merchant shipping logic.
Merchant workflow
Manage blocked contacts in one place.
Merchants can block emails and phone numbers manually, import lists in bulk, and unblock selected contacts later. Accepted orders are created in Shopify with clear COD and verification tags.

Free tools
Validate a phone number or email address.
Use the public tools for quick format, country, DNS, and pattern checks. They are generic tools and do not expose private CODProof scoring internals.
