# Barcode Variables

The **Barcode** category inserts a barcode image into the message.

You create barcodes with the Barcode Generator from a coupon list, a custom attribute, or manually entered data. Barcodes from a coupon list or a custom attribute are generated individually for each recipient during sendout.

> [!NOTE]
> Note
> 
> Barcodes are not supported in SMS messages. Barcodes stored in the Content Store are not available in this category. To use them, see [Use a Content Store Element in an Email](/v1/docs/use-a-content-element-in-an-email).

## Navigation Path

## Available Barcodes

The **Barcode** category lists all barcodes in your Mapp Engage system by name and ID.

If the category shows no barcodes, one of the following applies:

- There are no barcodes in your Mapp Engage system.
- You do not have permission to see barcodes. You need one of the following system permissions:
  - 170 **Barcodes: View and Edit Own Barcodes** (you only see your own barcodes)
  - 171 **Barcodes: View All Barcodes**
  - 172 **Barcodes: View and Edit All Barcodes**
- Your barcodes are stored in the Content Store.

## Format

The variable is inserted as an image tag. For example, the following variable inserts the barcode with the ID 104:

```plaintext
<img src="<%barcode.104%>">
```

You do not need to change the variable. During sendout, Mapp Engage replaces it with the barcode.
