# Terminal49 Test Tracking Numbers

> Use Terminal49 test tracking numbers to simulate successful, failed, and edge-case tracking request outcomes when validating your sandbox integration.

## Overview

This page includes test tracking numbers you can use to make sure your tracking request integration works as planned.

## What are test numbers?

Test numbers are deterministic request numbers for the Tracking Request API. Each number has a specific outcome, so you can test how your integration handles `tracking_request.succeeded` and `tracking_request.failed` without using a live shipment.

Test numbers do not simulate every milestone, ETA, LFD, or availability event. To test your webhook handler for a specific event payload, use the [Trigger Webhook](/api-docs/api-reference/webhooks/trigger-a-webhook) endpoint.

## Tracking request API

Shipments are created by making requests to the tracking request API.
When using the API , ensure that:

* you set the test number in `request_number` attribute in the request body
* you set the `scac` attribute to `TEST` in the request body

## Test numbers

| Number.           | Use Case                                                  |
| ----------------- | --------------------------------------------------------- |
| TEST-TR-SUCCEEDED | Test the `tracking_request.succeeded` outcome and webhook |
| TEST-TR-FAILED    | Test the `tracking_request.failed` outcome and webhook    |
