# Custom Lists

### About Custom Lists

Custom Lists let you create **custom screening lists** in ComplyCube. Use them to extend ComplyCube’s [AML Screening Checks](https://docs.complycube.com/documentation/product-guides/watchlist-pep-and-adverse-media/aml-screening-check) with your own internal or proprietary data.

Screen both **individuals** and **businesses** during **KYC** and **KYB**.

Typical lists include blocked customers, internal fraud lists, high-risk counterparties, and jurisdiction-specific risk lists.

### Common use cases

Use Custom Lists to improve screening coverage in cases like:

* **Internal watchlists**: Screen against your blocked customers and internal fraud lists.
* **Regulatory and enforcement lists**: Screen against industry-specific regulatory actions, enforcement notices, or prohibited entities relevant to your sector.
* **Shared fraud databases**: Screen against consortium or third-party fraud lists to identify known bad actors before approval.
* **Higher-risk portfolios**: Add bespoke risk lists for specific products or jurisdictions.

### How custom lists works

Once a Custom List is created, you can upload entities using **CSV files**, **API requests**, or an **SFTP integration**.

These lists are then included in AML screening checks alongside ComplyCube’s global datasets.
