What is Omocodia?

Omocodia occurs when two people have the same calculated Tax Code. The Revenue Agency resolves this by replacing some digits with letters.

Substitution table:

0→L1→M2→N3→P4→Q5→R6→S7→T8→U9→V

Control Character (CIN)

The last character is calculated with an algorithm that verifies the correctness of all previous characters. It is a letter from A to Z calculated using odd and even value tables.
