To provide the highest possible accuracy, we combine data from multiple sources. The main sources for new records are publicly available data, governmental data and manual additions/corrections. Based on the source of a new name, the name may have to be verified by a second source before it is added to our list. For example, if we add a name from publicly available data, this name may need a second verification, like a manual confirmation, before it is finally added to our database. You can find a list of supported countries here.
