What Is My IP Address, and How Does it Prevent Mortgage Fraud?

What an IP Address Is

An IP (Internet Protocol) address is a numerical label assigned to every device connected to a network. When you connect to the internet — from your home, your office, or your phone — your device is assigned an IP address by your internet service provider. This address identifies your general location (typically to the city or zip code level) and can be used to verify that online activity is consistent with your stated location.

IP addresses are not precise enough to identify a specific street address, but they are precise enough to identify a country, state, and general metropolitan area. This level of precision is sufficient for the fraud detection purposes that lenders use them for.

How Lenders Use IP Data in Fraud Detection

Modern mortgage origination platforms capture the IP address, device type, operating system, and browser information of the device used to complete the application. This data is compared against the borrower's stated information — address, employment location, and other details — to identify inconsistencies that may indicate fraud.

Common fraud patterns that IP data helps detect include applications completed from foreign IP addresses (suggesting identity theft or offshore fraud rings), multiple applications completed from the same IP address with different borrower identities, and applications where the IP location is inconsistent with the stated property location in ways that do not make sense for a legitimate transaction.

What Triggers Additional Verification

For most legitimate borrowers, the IP data is captured silently and never surfaces as an issue. Inconsistencies that can trigger additional verification include: using a VPN that routes your traffic through a foreign IP address, completing the application while traveling internationally, or using a device that is registered to a different location than your stated address.

If you receive a request for additional verification that seems related to your location or device, the simplest explanation is usually the correct one — you were traveling, using a VPN, or on a work device. Providing a brief explanation and completing the verification from your home network typically resolves the issue quickly.

Secure Application Best Practices

For the smoothest application experience, complete your mortgage application from your home network using a personal device. Avoid using VPNs during the application process, as they can route your traffic through an IP address that does not match your stated location. If you are completing the application while traveling, note this in the application or inform your loan officer so they can flag it proactively.
