# Create and Register DIDs

A Decentralized Identifier (DID) is a globally unique identifier that doesn't rely on a centralized registration authority.

## Create a new DID 

By default, a DID ("My DID") has been pre-created for you. This DID can be used for creating your first issuance or verification template.

If you need additional DIDs, you can create them by navigating to the **DIDs** section and clicking **"New DID"**.

When creating a new DID, you’ll need to fill in and select the information required:

* **Alias:** Name your DID for easy reference in the future.
* **DID Method:** A DID method defines how the DID is created (the format and structure), how you can verify and update information linked to that DID and where the DID is stored.&#x20;

{% hint style="info" %}
The number of DIDs you can create and the methods available depend on your subscription plan. Please review the DID limits tied to your subscription.
{% endhint %}

## Register DIDs&#x20;

You can request that the DIDs associated with your organization be listed in Gataca’s and EBSI’s public Trusted Registries.&#x20;

To register your DID in a Trusted Registry, submit a ticket. Please note that DID registrations are subject to approval by Gataca.
