Screen orders and sign-ups for fraud
Where a request originates is one of the oldest fraud signals there is. An order shipping to one country but connecting from another — or arriving over a VPN, proxy or data-center IP — is worth a second look before you authorize or fulfil. Geolocating the IP lets you hold the risky ones for review instead of eating a chargeback: the lost goods, the sale, and a $15–$100 dispute fee.
