Under Event → Discount codes all the event's codes are listed with their status (Active / Inactive) and a search box. You can filter by active and inactive. From each code's actions you can edit or delete it.

The uses tab shows every application of a code to a registration:

Export codes downloads all the discount's codes to Excel, for example to distribute them or reuse them in another event.

Import codes uploads an Excel file with already-generated codes. The import format is exactly the same as the export one, so you can export one event's codes and import them straight into another event. This is ideal for reusing code series between editions of the same event.

To import external codes, download the Excel template, fill it in with your codes and upload the file (.xlsx or .xls).

You can modify any discount: limitations (uses and dates) and the fees it applies to, or set it to inactive without deleting it.

If a code has no use limit, it stays valid until it expires by date. Always review the limitations before distributing the code.
