# Display (custom) IDs
## What are Display IDs?
Replace the automatically generated ID created by Content Controller for **Accounts**, **Content**, **Equivalents** and **Bundles** with your own Display (also known as custom) ID. These IDs can be used for searching, reporting and audit logs or interacted with via the API.
{% hint style="warning" %}
If you are integrated in any way with Content Controller or utilize the Automation API. Please make sure to check with your Manager or Engineering team before changing an ID.
{% endhint %}
### Some things to keep in mind
Before working with these custom IDs there are a few limitations to be aware of.
* The IDs must be unique
* They cannot be more than 1000 characters
* And they cannot contain any of the following: &$+,/:;=?@# <>\[]{}|^%
### Setting & editing IDs
To set a custom ID this can be done via the API or the UI. Within the UI, you have the option of applying an ID when importing a course or from the details panel for those already in your library. Similarly, this applies to Accounts, Equivalents and Bundles.
#### During content import
1. Navigate to the **Content** section
2. Click the **+ Add** button then select the Course option.
3. Here you will see a checkbox “**Automatically generate ID**” selected. Uncheck this box to present a new text field where an ID may be set.
4. Enter your ID and upload the course as normal.

The same steps above also apply when creating an **Equivalent** or **Bundle**.
