The [[wp:New York State Identification and Intelligence System|New York State Identification and Intelligence System phonetic code]], commonly known as NYSIIS, is a phonetic algorithm for creating indices for words based on their pronunciation.
The goal is for homophones to be encoded to the same representation so that they can be matched despite minor differences in spelling.
;Task:
Implement the original NYSIIS algorithm, shown in Wikipedia, rather than any other subsequent modification.
Also, before the algorithm is applied the input string should be converted to upper case with all white space removed.
An optional step is to handle multiple names, including double-barrelled names or double surnames (e.g. 'Hoyle-Johnson' or 'Vaughan Williams') and unnecessary suffixes/honours that are not required for indexing purposes (e.g. 'Jnr', 'Sr', 'III', etc) - a small selection will suffice.
The original implementation is also restricted to six characters, but this is not a requirement.

{{trans|Python}}
This is a translation of [[Python]] to ensure that these results are consistent.
This allows them to be tested against a known output from another solution.
If any of the <code>check-equal?</code>s fails, it will print an error message.
None of them fail, so no output is seen.
I’ve gone out of my way to number the rules — which may make it a little
verbose.

This implementation removes common name suffixes similar to the reference implementation, even though it is not specified in the task description or on the linked [[wp:New York State Identification and Intelligence System|NYSIIS]] page. This algorithm isn't too friendly to certain French kings. :)

=={{header|REXX}}==
This REXX version allows a blank to be inserted into names by using an underscore or underbar character [ <big><big>'''_'''</big></big> ].
Code was added to the REXX program to allow various titles.
Any post-nominal letters (generational, honorific, professional,or other) ending in a period is ignored as well as most Roman numeral letters.
If the rule of only returning (up to) six characters is to be enforced, then the last REXX statement should be
replaced with:
<syntaxhighlight lang="rexx">return strip( left(key, 6) ) /*return the leftmost six characters. */</syntaxhighlight>
