    • 4: gender = mostly masculine
    • 5: gender = unisex
    • 6: name not recognized
    • 7: input error, most likely because the name was shorter than 3 characters
    • 8: invalid address
    • 9: technical error
  • firstname: if the result is “1” this field contains the recognized first name, capitalized
  • nameday: if a valid first name was found, and there is a name day defined for it, then the date for its next occurence is returned. Next occurence means: if the name day is today or still in the future then a date for the current year is returned, otherwise for the following year. If the full date is not important, then month and day of the name day can be easily extracted from the date.
  • avgage: this field contains the average age for holders of a given first name, or “0.0” if there is not sufficient data for a prediction. Many first names follow historic or fashion trends so they can be attributed to a certain age group. In the case of rare or always popular names such predictions cant’t be made, then the result “0.0” is returned.


Each execution of the check will be documented as a business event (database table business_event) with type 102.
