A WhatsApp QR code gives customers a direct route into a chat with a selected phone number. Scanning it with a phone camera opens WhatsApp with the number already entered; you can also prefill a message. This is useful on reception desks, packaging, event material, or printed local advertising because the physical code can invite a conversation without asking visitors to type a long number.
The important decision is whether the phone number and prefilled text must remain editable after printing. A static code stores those details permanently, while a dynamic code lets an account holder change them without reprinting. QREasy supports both approaches, so the right choice depends on how long the material will be used, who owns it, and how often the details are likely to change.
Key takeaways
A WhatsApp QR code can open a chat with a selected number and optional prefilled message
Static codes are fixed, while dynamic codes allow the linked details to change 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.
Dynamic WhatsApp QR codes require a QREasy account and use the plan's dynamic-code allowance
The recipient always decides whether to send the prefilled WhatsApp message
What a WhatsApp QR Code Does
A QREasy WhatsApp QR code uses a wa.me link to open a WhatsApp chat with the specified phone number and optional prefilled message. The visitor does not have to type the number manually. The code does not send the message by itself: after scanning, the recipient sees the text and remains in control of whether it is sent.
Before generating the code, write the destination number exactly as it should be dialed, including the appropriate country code. Decide whether a prefilled message adds useful context, such as requesting an appointment, asking for a quotation, or confirming interest in a product. Keep it short and make the next step easy to understand.
The two formats differ in where the destination lives. A static WhatsApp QR code contains the phone number and optional message itself, so those values remain fixed in the image. A dynamic code uses a managed link whose destination can be changed in QREasy. That makes the dynamic format more flexible, but it adds an account and plan dependency.
Use static when the number and message are fixed for the life of the printed material and a future replacement would be straightforward.
Use dynamic when the same printed code must lead to a number or message that may change later.
Changing a static number or message requires generating a new code and replacing the affected printed copies.
A dynamic code requires a QREasy account and counts toward the dynamic QR codes included in the selected plan.

How to Create a WhatsApp QR Code Online with QREasy
Start in the QREasy QR code generators area and open the WhatsApp option. Enter the destination number in the international format that WhatsApp should dial, including the country code. If a prefilled message will help, write it as one clear invitation rather than a long block of text. Leave the message empty when opening a blank chat is more appropriate.
Choose static if these details are final for the life of the printed piece. Choose dynamic if the number or message may need revision and the printed code should remain reusable. Generate the code from the completed entries, inspect the result, and prepare the file for its intended size and placement. The dynamic choice is the one that allows later edits without producing another image.
Before production, scan the generated code with another phone and confirm that it opens the intended chat, shows the correct number, and contains the expected prefilled wording. Check capitalization, spacing, and punctuation in the message. For a compact walkthrough of the same creation flow, see How to Create a WhatsApp QR Code in QREasy.
Decide What Must Stay Changeable
Choose static when the destination is certain and the printed piece has a limited useful life. A fixed number on a short-lived event handout, for example, may not justify a managed dynamic link. Every listed QREasy plan includes unlimited static QR codes, so one-off materials do not consume any dynamic-code allowance. The trade-off is that any later change requires new prints.
Choose dynamic when one printed code will remain visible for months or years. This suits counters, storefronts, packaging, and event signs that may outlive a phone number, team assignment, or campaign message. Updating the linked details then avoids reprinting every copy. Make sure the person or team responsible for those materials has access to the QREasy account, so the linked destination is not left without an owner.
Will the item remain in use after the current number or campaign ends?
Would replacing every printed copy be easy or expensive?
Who will be responsible for checking and updating a dynamic destination?
How likely is the message itself to change, not just the phone number?
Does the rollout require several dynamic codes, and does the account have enough capacity?
Test, Deploy, and Check Plan Limits
Dynamic capacity comes from the account plan. The listed Free plan includes 1 dynamic QR code, Lite SME includes 50, and Business includes 357; each listed plan includes unlimited static QR codes. Compare the current allowances on the QREasy plans page before choosing a format for a print run or rollout. If several reusable destinations are needed, count them against the dynamic allowance rather than assuming static and dynamic limits are interchangeable.
Create a simple register for every live code. Record its type, phone number, message, QR format, printed location, and owner; for a dynamic code, also record when the destination was last checked. After changing a dynamic destination, retest one physical copy to confirm that it reaches the intended chat. This check helps catch a mistyped number or outdated wording, and the QR image itself does not need to be regenerated to apply the fix.
Finally, treat the QR code as an invitation rather than an automatic message. A prefilled message can reduce typing and set expectations, but WhatsApp still gives the recipient the final choice about whether to send it. Keep the wording relevant and easy to act on, especially when the code appears in a public place where many people may ignore it.
Frequently asked questions
Use static when the phone number and message will not change and the printed material has a short life. Use dynamic when the code will remain in circulation or its destination may need updating. Dynamic codes require a QREasy account and an available dynamic-code slot.
No. It opens a WhatsApp chat with the selected number and optional message. The recipient reviews the message and decides whether to send it, so the code cannot guarantee that a conversation will begin.
Only a dynamic code supports changing the linked phone number or message without reprinting. A static code contains those details permanently; changing either one requires a newly generated code and replacement of the printed copies.
Confirm the full international phone number, test the scan and prefilled text, choose static or dynamic based on likely updates, and verify the dynamic-code allowance in your QREasy plan. Dynamic codes require an account; static codes are unlimited in the listed plans.
