Soundex is an indexing system for encoding surnames.

  • It provides an anonymised representation of a surname.
  • It consists of the initial letter of the surname and three digits.
  • No soundex is unique to a single name, and a name cannot be recreated from a soundex code.

Please use the soundex calculator below in order to provide a soundex code on all forms:

  • Type the surname in the first box and note the resulting soundex.
  • Names entered are not stored or retained in any way.
