Use case
Create a QR code to call a phone number
A phone number QR code offers to call your number as soon as it is scanned. Customers no longer have to copy digits from a sign or a moving van: they scan, their phone shows the number ready to dial, and all that is left is to start the call.

Why choose a QR Code?
Concrete benefits for your business
No typing mistakes
The number appears exactly as you saved it, with no digits swapped or missed by the customer.
Useful where people can't write it down
On a parked vehicle, a poster or a construction site sign, scanning is faster than copying a number.
A call, not a search
Customers go through neither a search engine nor a directory: they reach your line directly.
Situations where a phone QR code wins you a call
Tradespeople benefit first: on the back door of a van, a number can be hard to note down at a red light or in a parking lot. A QR code nearby lets a passer-by scan and keep the number in their call log. The same goes for construction site signs and shop signs.
Classified ads posted in shops or on a corkboard benefit too, as do “for sale” or “for rent” signs. Interested people call right away instead of taking a photo of the ad that they will later forget in their gallery.
Emergency and on-call numbers
In a building, a technical room or a piece of equipment that needs servicing, a QR code to the on-call number lets people reach the right service quickly, without digging through a binder. Place it somewhere visible and always add the number written in large type: in an emergency, nobody should depend on a scan.
For numbers that change over time, such as a rotating on-call duty, a QR code containing a fixed number is not ideal. It is better to point a dynamic QR code to a page whose content you edit, so the display stays accurate without visiting every room again.
Preparing the number and planning for change
Enter the number in international format, with the +33 country code followed by the number without the leading zero. This format works on every phone, including foreign ones. Then test the scan on two different devices and check that the number shown matches exactly the one printed next to the code.
Think about the material's lifespan from the start. Vehicle lettering or a shop sign stays in place for years. If your number might change, choose a dynamic QR code or a links page with a call button: you can update the number without redoing the material.

Best practices for an effective QR
Our recommendations to maximise your results
Number in plain text too
Always write the number next to the QR code: some people prefer to dial it, and it is essential in an emergency.
+33 format
Save the number in international format so it also works with a foreign phone.
Test in real conditions
Scan the code at the distance and in the lighting where it will be read, especially on a vehicle or a sign.
Plan for a change
For long-lasting material, a dynamic QR code or a links page saves you from redoing everything if the number changes.

Frequently asked questions
Everything you need to know about this solution
No, the phone offers to call the number; the person confirms the call themselves.
