# Do Ticket Numbers have to be unique?

Ticket Numbers in Fast-Weigh must be unique if the Order-Products are the same. 

Order-Products are tied to:

* Location
* Order
* Customer

Even though you can use the same ticket numbers for different locations we recommend using unique number sequences for each location.
