This application is primarily designed to check whether the format of an identifier complies with international standards and is therefore valid for that context.
Not only does this improve confidence in your data, but in case it can't be validated for the type of data you expected, it also helps you determine what type of identifier it might be. In the detail views you can get additional information about the applied validation rules which can be interesting, especially for use in third-party applications like spreadsheets.
If you wish you can make comments and be happy to read your suggestions. You can also contact me through the app (Linkedin link).
Comments will not be approved to be posted if they are SPAM, abusive, off-topic, use profanity, contain a personal attack, or promote hate of any kind.
