# How to Get Barcode Location
10+
11+
Once a barcode is found, you could be inclined to highlight it on the image for a better user experience. In this article, we will explain how to get the coordinates of the barcode so that they can be used to highlight the barcode.
12+
13+
## BarcodeResultItem
14+
15+
A barcode result is returned as a `BarcodeResultItem` which provides a method `GetLocation` to get the result coordinate points. The result points are listed in clockwise order, starting from the top-left point of the barcode area. The next section will explore the different code snippets for each supported programming language.
16+
17+
## Code Snippet
18+
19+
The following code snippet shows how to get the coordinates of the barcode:
