Soundex

Shown below is the "Soundex" system used to group names that have the same or a similar pronunciation but may have variant spellings. The "Soundex" system is a combination of the first letter of the last name of a person and a three digit numeric code for the consonants (excluding h, w, and y) in the next few letters of the person's surname.

Soundex Coding Guide

Do NOT code these letters: a, e, h, i, o, u, w, y

To work out the "Soundex" code for a particular name (using "Kuhne" as an example), begin with the first letter of the last name (K), skip over the letter "u" because it is a vowel and the letter "h" because it is not coded, use the number "5" in place of the letter "n", and skip over the "e" because it is a vowel. Every "Soundex" code must be a three-digit number. If, as is the case with the name "Kuhne" there is only a letter followed by one digit, add two zeros to complete the code (Kuhne= K-500). If a name contains double letters or two letters next to each other that fall within the same equivalent grouping, use the code number once and follow it with a zero. For example, for a name like "Hammerschmidt", the code would be "H-506" ("H" is the first letter of the surname, the "a" is ignored because it is a vowel, only the first "m" of the pair is coded with a number "5", a zero is substituted for the second "m", the "e" is skipped over because it is a vowel, and the "r" is coded as the number "6"). Once you have three digits in the code, STOP.

"SOUNDEX" CODES CONSIST OF A LETTER AND THREE (ONLY) DIGITS.

If several surnames have the same code, they are arranged alphabetically by given name.

Prefixes to surnames such as "van", "Von", "Di", "de", "le", "D" and others are sometimes disregarded in alphabetizing and coding.
