# How to Find Your UET Tag ID in Microsoft Advertising

> Locate your Universal Event Tracking (UET) Tag ID in Microsoft Advertising for use with Upstack Data.

Your **UET Tag ID** is a numeric identifier for your Microsoft Advertising tracking tag. You'll need this ID to configure the Microsoft Advertising destination in Upstack Data.

## Steps

<Steps>
  <Step title="Sign in to Microsoft Advertising">
    Go to [ads.microsoft.com](https://ads.microsoft.com) and sign in to your account.
  </Step>

  <Step title="Navigate to UET Tags">
    In the top navigation, click **Tools** → **UET Tags** (under Conversion tracking).
  </Step>

  <Step title="Find your UET Tag">
    Locate your existing UET Tag in the list. If you don't have one, click **Create UET tag** to create a new one.
  </Step>

  <Step title="Copy the Tag ID">
    The **Tag ID** is displayed in the list view or tag details. It's a numeric value (e.g., `12345678`).

    Copy this ID — you'll need it when configuring the Microsoft Advertising destination in Upstack Data.
  </Step>
</Steps>

## Where to find the Tag ID

The UET Tag ID appears in several places:

* **UET Tags list:** The ID column shows the numeric Tag ID for each tag
* **Tag details:** Click on a tag name to view its details, including the Tag ID
* **UET Tag code snippet:** The Tag ID appears in the JavaScript snippet as part of the `uetq` initialization

## If you don't have a UET Tag

If you don't have an existing UET Tag:

1. Click **Create UET tag** in the UET Tags section
2. Give your tag a descriptive name (e.g., "Upstack Tracking")
3. Optionally add a description
4. Click **Save**
5. Copy the new Tag ID

<Note>
  **Important:** Use the same UET Tag ID for both your browser UET Tag and Upstack server-side delivery to ensure proper event deduplication.
