A WhatsApp QR code gives people a direct route into a conversation with a chosen phone number. With QREasy, the code can open a WhatsApp chat through a wa.me link and place an optional message in the message field, ready for the visitor to review. The visitor still decides whether to send it, so the code starts the interaction without sending anything on their behalf.
Static and dynamic codes serve different operational needs. A static code contains fixed details, which is simple but must be replaced if the number or message changes. A dynamic code keeps the printed code in place while its destination can be edited through a QREasy account. This guide shows how to choose between them, set the details, test the result and decide which listed plan matches your volume of dynamic codes.
Key takeaways
Use a static code when the number and message are unlikely to change
Choose dynamic when you need to edit either detail without reprinting
Many professionals struggle to choose between a microsite and a landing page. This guide explains the key differences and shows why a microsite is often the better fit for building a simple, professional, and always-on digital presence.
QREasy helps you reduce follow-up friction in two ways: let people save your contact instantly to their phone contacts with a vCard QR, or keep your micro page in Apple Wallet or Google Wallet so you can open it anytime and let people scan through to your fuller digital identity.
Prepare accurate property photos, descriptions, and viewing access steps for a QREasy real-estate microsite, separating confirmed details from items to verify at the viewing.
A microsite is a compact, focused digital presence built to explain who you are, what you offer, and what people should do next. This guide explains the definition, benefits, examples, and differences between micro pages, microsites, landing pages, and full websites.
A link in bio page is useful when you mainly need a simple hub for social links. A micro page or microsite is the better choice when you need a stronger branded presence that explains who you are, what you offer, and what people should do next.

Understand what a WhatsApp QR code does
A WhatsApp QR code is a shortcut rather than an automatic message. The encoded wa.me link identifies the phone number and, when supplied, the text that should appear in the draft. After scanning, the person lands in the intended chat and can decide what to send. Nothing is transmitted merely because the code was scanned.
This makes the format useful for shops, independent professionals, service teams and event organisers who want a low-friction contact route. Decide in advance what should happen after the scan: open a general enquiries chat, start a request for information, or reach a particular team. The destination and the wording should reinforce the same purpose.
Choose between a static and dynamic code
A static WhatsApp QR code contains the destination details themselves. It is a straightforward option when the phone number and message will remain fixed. If either detail changes, however, QREasy must create a new static code and you must replace the old printed or shared version.
A dynamic WhatsApp QR code separates the printed code from the editable destination. It requires a QREasy account, uses one of the dynamic QR codes included in your plan, and lets you change the number or message later without reprinting. This is the better fit for reusable materials, temporary campaigns or a business that may move the conversation to another number.
Plan capacity is the deciding factor for dynamic use. The Free plan includes one dynamic QR code and unlimited static codes; Lite SME includes 50 dynamic and unlimited static codes; Business includes 357 dynamic and unlimited static codes. Compare those allowances with the number of locations or reusable assets you need to manage, and check the full allowances on the QREasy plans page.

Create the code with QREasy
Begin with QREasy’s WhatsApp QR code creation walkthrough, then open the relevant tool from the QR code generator library. Select the WhatsApp generator and work through the destination fields before generating the final artwork. The essential inputs are the phone number, the optional prefilled message and the static or dynamic format.
For a static code, generate the code after checking those details. For a dynamic code, sign in to your QREasy account because the service must connect the QR code to one of the dynamic codes available in your plan. Keep the printed code and its editable destination record together; that association is what makes later changes possible.
Open the WhatsApp QR generator and select the format required for your use.
Enter the complete destination phone number in international format.
Add the optional message that should appear in the new chat.
Use a plan dynamic code and save the link between that code and its destination.
Generate the code, test it on a second phone and only then print or distribute it.
Set the phone number and prefilled message
The number must identify the phone or business line that should receive the WhatsApp conversation. Enter it in full international format, including the country code, and remove spaces, brackets or punctuation from the number used in the generated wa.me destination. If the business serves several countries, check each intended number separately rather than assuming a local format will work for everyone.
The prefilled message is a draft, not a compulsory instruction. Leave it empty when opening the chat is enough, or write a short sentence that helps the recipient continue. For example, “Hello, I would like information about your services.” gives a visitor context, while a specific request such as “Hello, I would like to ask about a consultation.” makes the next step clearer.
Confirm that the number includes the correct country and area code.
Read the message as a customer would and remove wording that does not support the intended action.
Keep the first message short enough to review easily on a phone.
Remember that the visitor can edit or discard the draft before sending it.
Change details without replacing printed codes
With a static code, changing the phone number or message creates a different encoded destination. You then need a new QR image and must update every physical card, poster, package or digital placement using the previous one. A static code is therefore most convenient only when its details are genuinely stable.
With a dynamic code, open its destination record in QREasy, replace the number or edit the message, and save the change. The existing QR code can remain in place because it points to the editable destination rather than containing the final details permanently. This is why a dynamic WhatsApp QR guide is worth reading alongside your print run, since the destination can still be adjusted afterwards.
Correct a typo in the message without replacing cards or posters.
Move a reusable code to a different phone number when ownership changes.
Update wording for a new offer, service period or enquiry route.
Retest the same printed code after saving each destination change.
Test, print and share the code
Test before distribution, using a phone other than the one used to create the code. Scan the exact image or link you intend to publish, confirm that WhatsApp opens the intended conversation, and check the recipient number character by character. Verify that the prefilled text appears in the draft, can be edited and is not sent automatically.
For physical use, print a test at the size and on the material planned for deployment. Place it on a flat, high-contrast surface with an unobstructed border, and avoid adding another design layer over its modules. For digital use, check the link on both mobile and desktop connections where possible. The practical guide to using a WhatsApp generator offers a useful final review sequence.
Scan the final version, not an earlier export or copied screenshot.
Check the displayed name and number against the intended contact.
Confirm the message appears before the visitor presses send.
Retest after every dynamic destination or message update.
Keep a record of which physical placements use each dynamic code.
Frequently asked questions
Choose a static code for fixed details and simple, one-off distribution. Choose a dynamic code when the number or message may change and you need to keep printed materials in place. A dynamic code requires an account and uses plan capacity; static codes are unlimited across the listed plans.
No. The QR opens a WhatsApp chat with the number and optional message ready as a draft. The visitor reviews it and chooses whether to send, edit or discard it. This keeps the visitor in control of the conversation.
For a dynamic code, yes: edit the number or message in QREasy and the existing code can remain in place. For a static code, no: the details are encoded in the image, so changing either one requires a new code and replacement of every published copy.
Free includes one dynamic QR code and unlimited static codes, with seven days of analytics history. Lite SME includes 50 dynamic codes and 90 days of history; Business includes 357 dynamic codes and 90 days. Choose based on how many reusable dynamic destinations you need, then review pricing.
