International Social Security Number Validator


Social security number lookup

This tool is perfect if you want to validate a social number, an identification code or a fiscal code from any country. This checker will take your identification code and will verify if it is valid or not. We verify things like sex, age, province and we ensure that number is legit or not. We support all the biggest countries like United States, China, United Kingdom, India, Canada and countries from Europe like France, Spain, Italy and Germany. For example, Germany doesn't have an identification code for citizens but has a fiscal tax code.

Every country has different rules regarding the personal codes. We tried to gather all the rules to help you validate the identity of a person. Almost all social security numbers contain a check digit or a control number. This is the primary check that a social number must validate. But are different rules that can be applied to see the validity. For example, most of the social numbers contain the person's birth year, so we verify that year to see if it is from the last century.
