# 2D barcodes about the box contents

Using OneDayBundle APP you can send information about the contents of the box to Amazon - the number of products and expiration dates (if necessary) for any FBA shipping.

When Amazon receives boxes at its warehouse, it will simply scan the 2D barcode to determine the contents of a particular box.&#x20;

Providing information about the contents of the box helps reduce the time between the arrival of products on FBA and their availability for sale.&#x20;

For example, the shipment in the screenshot below was received and processed within 24 hours.

For example, without 2D barcodes, when goods arrive at the Amazon warehouse, warehouse staff need to open each box, manually count each item, and input the data into the accounting system. This process can take quite a long time, sometimes more than a month.

IMPORTANT! Failure to provide accurate information about the contents of the box may result in future shipments being blocked and a manual acceptance processing fee being charged.

### How to set up 2D Barcodes?

In order to take advantage of this feature, you first need to activate it in the Seller Central settings. To do this, go to the section [Fulfillment by Amazon settings](https://sellercentral.amazon.com/gp/ssof/configuration/index.html/ref=xx_fbasettings_dnav_xx) **=>Inbound Settings =>Edit**. Next, click on the **Enable** button and then check **2D Barcodes for Box Content Information**. Next, save with the **Update** button.&#x20;

After that, go to your [OneDayBundle account settings](https://beta.onedaybundle.com/settings) and enable the "**Use 2D-barcode**" option.&#x20;
