The Letters A, E, I, O, U, W, Y, and H are disregarded. To apply the SOUNDEX to your surnames, follow these steps:
1. Use the first letter of the surname to begin the code.
2. Cross out all the vowels and the letters W, Y, and H in the surname.
3. Using the table, assign an equivalent number to the first three letters left in the surname.
4. Disregard any remaining letters in the surname.
If the surname has less than three letters left, assign zeros to those places.
Further refinements:
Double letters are treated as one and coded with one number; thus 2 L's will be 4.
Two or more letters with the same code number that appear in sequence in a surname are assigned one number; thus CK in Dickson is coded as 2, not 22. Szalay is S400.
A name that yeilds no letters is assigned three zeros, thus Chu becomes C000.
Code names with prefixes, such as Van, Von, De, Le, with and without the prefix. You may find it either way in the Soundex.
