## Testing Notes

When testing Dynamic Validation, create a barcode using the following format:

LocationPrefix=DynamicValidationPrefix-TicketNumber

1. Go to [https://barcode.tec-it.com/en/](https://barcode.tec-it.com/en/PDF417?data=This%20is%20a%20PDF417%20by%20TEC-IT)
2. Select **Linear Codes** > **Code128**.
3. Enter the full barcode value using the format above.

**Example:**

For a **Boston Red Sox** event, the barcode would be:

TBN=ABCD-12345678

Note

The **TBN**prefix is specific to **Boston Red Sox** events. The image below is provided for demonstration purposes only.

**TBN=ABCD-12345678**

When configuring the **Minimum Length** and **Maximum Length** fields in the Admin Portal:

- **Do not account for the** LocationPrefix= (for example, TBN=).
- **Include** the hyphen (-), as it counts as a character.

For the barcode:

TBN=ABCD-12345678

Configure:

- **Minimum Length:** 4
- **Maximum Length:** 13
