# Editing an Identifier Element

> Configure identifier element properties: type (Barcode Only, Barcode with Digits, Digits Only), EAN13 or EAN8 barcode, orientation, and custom values.

The standard size of an identifier is 46x12 mm.

For each **identifier** element, the following properties can be specified: position and size, type, orientation and value.

**Identifier** element properties do not depend on the form type.

You can change the properties of the **identifier** element in the Element Properties window located in the bottom right corner of the [main window](/flexi-capture/form-designer/main-program-window). The Element Properties window is displayed only if **View →** Element Properties is selected on the main menu.

## Element

**Type** — Identifier

**ID** — A unique identifier of the element.

## Position and size

**Left** — Sets the distance you wish between the left edge of the form and the element with no left indent.

**Top** — Sets the distance between the top edge of the form and the element.

**Width** — Sets the width of the **identifier** element.

**Height** — Sets the height of the **identifier** element.

## Identifier

**Type** — Sets the type of **identifier**:

* Barcode Only
* Barcode with Digits
* Digits Only

**Barcode type** — Selects the type of barcode if the identifier type is set to **Barcode Only** or **Barcode with Digits** and if the Custom value option is selected.

Available barcode types:

* EAN13
* EAN8

If the Custom value option is not selected, the Barcode type will be grayed out. The EAN13 barcode type will be used.

**Orientation** — Sets the orientation of the barcode:

* Horizontal
* Vertical

**Value** — The value of the **Identifier**.

Identifier values can only be changed if the Custom value option is selected. For EAN13, custom values must contain 12 digits and for EAN8 custom values must contain 7 digits. Longer or shorter values or characters other than digits are not allowed. An additional control digit is added at the end of the string within the barcode body.

If the Form identifier or Page identifier option is selected, the identifier will be assigned a value automatically when the form is published. Before a form is published, it has **Editable** status and no identifier value is yet assigned.

**Form identifier** — Uses an element as a form identifier.

**Page identifier** — Uses an element as an identifier for the current page.

**Custom value** — Allows custom values for an identifier. This option is not available for **Digits Only** identifiers.
