In brief
An identifier assigned by the tax administration, not a code to generate with a calculator. If Sportello Unico or Questura already assigned one, do not request a second. Tax-office allocation uses AA4/8 with valid ID. Distinguish first allocation, correction and replacement; check the office’s submission channel. Do not give the code to the chat.
