What is a receipt number on a receipt?*

Receipt Number on a Receipt is generally a serial number that’s generated automatically by a Merchant’s billing / collections / POS software.

In some countries, Receipt Number conforms to some rule (e.g. Mod10 / Luhn10). This helps their Tax Authority and other parties to ferret out a good number of fake receipts used to claim tax deduction for unincurred expenses.
