One code, and the chat is open

Your number and the message you want to receive. Whoever scans it lands in the conversation with you.

  • Nobody has to save your number first.

How it works

How to make your WhatsApp code

Write the number in international format

Country code against the number, no +, no 00, no leading operator zero. No spaces and no dashes either.

Pre-write the message you want to get

“Hi, I'd like information about…” saves the first awkward line. It is optional, and the sender can always change it.

Test it before you print it

Scan it with another phone and check it opens your chat. A wrong digit shows up in two seconds rather than in a thousand flyers.

There is no plain text inside this code: there is a wa.me address carrying your number and, if you want, a message already written. Scanning it opens WhatsApp on the conversation with you, that text waiting in the box. The person can delete or rewrite it before sending, so it steers the enquiry rather than putting words in their mouth.

The number has to be in international format with nothing decorative: country code and number run together, no plus sign, no leading zeros, no spaces or dashes. For Ecuador that means 593 followed by the number without its leading zero. This is what breaks most of these codes — one extra zero and WhatsApp opens a screen saying the number is not valid.

The number also has to have WhatsApp active on it. The code cannot check that — it is generated offline — so an office landline or a line cancelled last week produces a code that scans perfectly and leads nowhere. Testing it with a second phone before it goes to the printer is worth the minute.

And because the content travels inside, changing your number means remaking the code and replacing everything already printed. That is the trade for working with no middleman: nobody counts your scans, but there is no dashboard to redirect the code from the day your line changes.

Questions about WhatsApp codes

Do people need to save my number to message me?
No, and that is the point. The code opens the conversation directly, so nobody goes through their contacts first. Your number is still visible in the chat, as in any conversation.
Can I pre-write the message?
Yes. It appears already typed in the text box, ready to send. It is not sent for them: the person reads it, edits it if they like and decides to send it.
Does it work with WhatsApp Business?
Yes. The address is the same for a personal and a business account; what decides where it lands is the number, not the account type.
I changed my number. Can I update the code?
The number is written inside the code, so you generate a new one and replace what is printed. No redirect is possible because there is no server in between.
Will I know how many people scanned it?
No. The code passes through no counter of ours or anyone else's. If you need that measured, the site you point at would have to do it — and this code goes straight to WhatsApp.
