# Customise the short URL

Every dynamic QR code redirects through a short URL. The domain belongs to Unitag - or to you, on a Dynamic Pro code - but the suffix at the end, the part that identifies this particular code, is yours to choose. A suffix someone can read tells them where they are about to land, which is the difference between a link that looks deliberate and one that looks like a random redirect.

> Only while the QR code is being created
>
> The suffix is set on the creation form and nowhere else. Once the QR code is published it is encoded for good: there is no way to edit it afterwards, and the only route to a different suffix is a new QR code. Suffixes are also unique across Unitag, so one that is already taken is not available to you.

To choose the suffix of a short URL:

- Open the QR Codes app.
- Click Create a QR Code.
- In **General information**, beneath the destination field, click **change short URL**.

![The same form after clicking the link: a Short URL panel showing the https://opn.to/ prefix with an editable suffix beside it](https://www.unitag.io/documentation/images/qrcodes/en/qr-codes-short-url-content.webp)

- Type the suffix you want after the https://opn.to/ prefix. Keep it short and readable — it is the part people will see.
- Click Submit and preview to continue.
- Finish creating the QR code — the suffix is saved with it.

The suffix is also where UTM parameters go if you want scans of this QR code to arrive in Google Analytics already attributed to a campaign.
