A phone call QR code gives people a direct route from a poster, package, leaflet, or screen to a pre-filled phone dialler. After scanning, they can review the number and decide whether to call. It does not place the call automatically. That final confirmation keeps the experience familiar and lets the person check the destination before making contact.
The practical decision is whether the number should ever change. A static QR stores the phone number in the code itself, so a new number requires a new QR image. A dynamic QR keeps the destination editable in your QREasy account, allowing you to update the associated number later without generating and reprinting the code. The sections below cover both routes, testing, and maintenance.
Key takeaways
Static call QR codes are simple and fixed; if the number changes, create and redistribute a new code
Dynamic call QR codes need a QREasy account and an available dynamic code, but the associated number can be changed without reprinting
Enter the complete international phone number, then test the QR on more than one phone before using it publicly
A scan opens the dialler with the number ready; the recipient still chooses whether to place the call
How a phone call QR code works
When a person scans a phone call QR code, the phone reads the embedded instruction and opens the dialler with your number already entered. The number is represented through a tel link. The device may display the full number, including the country code, depending on the phone. The important point is that scanning prepares the action rather than completing it.
This makes the format suitable for business cards, reception desks, event packs, product packaging, service vehicles, and other places where a phone number is easier to use than typing. It also removes a long manual entry task. For more background on the scan-to-dialler journey, see how a QR code triggers a phone call on a smartphone and call QR code use cases.
The QR opens the phone's dialler and fills in the set number.
The recipient reviews the destination and decides whether to call.
The code does not make the call without the recipient's action.
A correct destination becomes a tel link that the operating system can open.
How to create a QR that opens the dialler
Start with the phone number, not the layout. Enter the number in international format so callers can reach it from different countries. A fictional example is +44 7700 900000. Keep the plus sign and country code unambiguous, and check every subscriber digit against your source record. If the generator rejects spaces or other separators, enter the value continuously.
Open the QREasy phone call QR generator and decide which type fits the expected lifespan of the printed material. For a static QR, create the code with the number, test it, and use the resulting image wherever the phone number is fixed. This is the straightforward option when the destination is unlikely to move or change.
For a dynamic QR, sign in to your QREasy account, choose an available dynamic QR code under your plan, and associate it with the current phone number. The same printed image can then remain in place while you manage the destination later. QREasy also supports other QR formats for different sharing needs, as shown in its QR code generators.
Keep the number in international format, including the plus sign and country code.
Choose static for a permanent destination and dynamic for a number you may need to edit.
Create the code before artwork is printed so the final image can be checked.
Test the exact code in the placement where you plan to use it.
Add a short prompt such as Scan to call so people know what the QR is for.
Scan this code with your phone camera to open the QREasy phone call QR code page.
Static or dynamic: differences and use cases
A static call QR encodes the destination directly into the symbol. Anyone who saves or scans it gets the number that was entered at creation. Once created, it does not depend on a QREasy account to function. A dynamic call QR instead remains connected to a destination you can manage in QREasy, subject to your account and the dynamic-code allowance in your plan.
Use a static code for a permanent office line, a fixed product support contact, or printed material that is unlikely to be reused. Choose a dynamic code for temporary campaigns, seasonal promotions, changing departments, or several printed items that may need to reach the same updated number. The key difference is not scan speed or image quality; it is how easily you can change the destination later.
QREasy's current plan structure gives every listed plan unlimited static QR codes. The Free plan includes one dynamic code, Lite SME includes 50, and Business includes 357. Check QREasy plans for the current allocation before choosing a dynamic code, especially if several campaigns or locations need separate destinations.
Static: the phone number is encoded directly in the QR image.
Static: choose it when the destination will remain fixed for the life of the print.
Dynamic: the associated destination can be edited through QREasy.
Dynamic: choose it when one printed code may need to reach a different number later.
How to check the tel link before sharing
Testing catches formatting and placement errors before customers encounter them. Scan the code yourself and confirm that the dialler opens with the intended number, not a partial value or an unwanted character. Compare the displayed digits with your source record digit by digit, including the country code. A useful reference is a practical phone-call QR code creation walkthrough.
Test with a second phone if the code will be used by different devices or operating systems. Use the scanning method your audience is likely to use, and check the code at its final size and under the lighting where it will appear. If it is part of artwork, make sure it is not stretched, cropped, or covered by another design element.
Scan from the normal camera app, not only from a saved test page.
Confirm that the dialler shows the complete intended number.
Try another phone when your audience includes different device types.
Check legibility at the final print size and expected viewing distance.
Retest an existing dynamic code after changing its associated number.
How to change the number associated with a dynamic QR
To change a dynamic destination, sign in to QREasy, open the dynamic QR management area, find the code attached to the printed material, and edit the associated phone number. Save the new destination, then test the existing code again. Avoid announcing the change until the updated number appears correctly in the dialler.
Because the physical QR does not need to be regenerated, posters, cards, packaging, and signage can continue to point to the same code. Anyone who scans after the change should receive the updated number in the dialler. If an old number still appears, repeat the test and confirm that the destination update was saved before distributing further instructions.
A static code requires a different process: create a new QR with the new number, replace the old image, and test the replacement. This difference is why dynamic codes are useful for temporary campaigns and changing contact details. When you edit a shared dynamic code, every printed copy continues to use that same editable destination.
Identify every printed asset that uses the dynamic code before editing it.
Prepare and verify the new number in international format.
Edit the associated number in QREasy and save the change.
Rescan the existing code to confirm that the new number appears.
If the code is static, replace the image and update every printed copy.
Frequently asked questions
A static QR contains the phone number itself, so changing the number means creating a new code and replacing printed copies. A dynamic QR uses a QREasy-managed destination, so you can change the associated number later without reprinting. Dynamic codes require an account and an available dynamic code under your plan.
No. The scan opens the phone's dialler with the number filled in. The recipient can review it and then choose to place the call. This extra step prevents a scan from making a call without the person's knowledge and gives them a chance to check the number.
Yes, if the printed QR is dynamic. Sign in to QREasy, locate the relevant dynamic QR, change its associated number, save, and rescan the existing code. A static QR cannot be updated in place because the old number is encoded directly in its image.
Use the complete international number, including the country code, such as the fictional +44 7700 900000. Enter it exactly as requested by the generator, and check the resulting dialler on a second phone if possible. This reduces ambiguity caused by different national dialing conventions.
