Data Validation by FraudGrade is a free Chrome add-on developed by FraudGrade. It offers a range of validation tools including IP Validation, Email Validation, Phone Number Validation, and Domain Validation.

IP Validation is a useful tool for preventing fraud by validating the IP address of online customers. It provides information about the general location of users based on their IP address. This can help businesses identify potential fraudulent activities.

Phone Number Validation helps businesses capture only good leads by verifying the validity of phone numbers at the point of entry. It uses up-to-date international numbering plans, carrier and line type detection, and location lookup to ensure accurate validation.

Email Validation verifies the deliverability and validity of email addresses. It detects typos and confirms if an email address exists with a reliable domain. This tool helps businesses clean their email addresses and prevent fraud by identifying disposable email services or free service providers.

Domain Validation detects if a domain is registered or not, if it's a parked domain or blacklisted. It provides information about the domain's creation date, expiration date, online status, and owner details. This tool is particularly useful for detecting fraud in a B2B scenario.
