# Ticket codes Ticket codes give you the ability to add unique codes to tickets. A good example is discount codes for public transport. Once you created the ticket code object you are able to add the unique codes. Per import you can add up to 3000 codes. The total number of codes is unlimited. Per ticket code you have the option to attach a [filter](/event/general/filters.md) for [members](/event/planning/members.md), and one for [form visitors](/event/accreditation/lists/forms/attendees.md). This ensures only the required subset receives these codes. {% hint style="info" %} If a person has already downloaded their ticket once, redownloads afterwards will still show the same ticket codes. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
