Opo Codes

SMS QR code generator

An SMS QR code opens the phone's messaging app with your number in the To box and, if you like, the words already typed, so a customer only has to press send. Opo Codes makes it for free in your browser, with no account, and checks it reads back before you print.

How to do it

  1. Open the generator with SMS already selected.
  2. Type the phone number that should receive the message, with its country code.
  3. Type the message you want pre-filled, for example a keyword or a request.
  4. Wait for the VERIFIED stamp, then download and print the code.

What is inside the code

The code holds an sms: link in the standard form with ?body= for the message text. Worked example: the number +880 1711 223344 and the message Send me the price list. The code holds sms:+8801711223344?body=Send%20me%20the%20price%20list.

The number keeps only its digits and a leading plus, and spaces in the message become %20. The older SMSTO: form works on Android only, so it is not used here. The sms: form is the one the generator builds because it is meant to work on both iPhone and Android.

Use it for a reason

A keyword code works well for a shop that answers messages by hand, for example one that asks for the word PRICES. Print the keyword next to the code so people know what will be sent.

The message is optional. Leave it out and the phone opens a blank message to your number.

Cost and privacy

The customer sends the message from their own phone, so their own plan pays for it. Everyone who scans can see the number you put in the code, so use a number you are happy to share.

Questions

Do I need the country code?

Yes, write it with the plus, as in +880. Without it a phone may treat the number as local to where it is.

Will the message send by itself?

No. The phone opens the message and the customer presses send.

Does it work on iPhone and Android?

The sms: form is built to work on both. We have not tested every model, so scan your printed code once yourself.

Can I change the number later?

No, the number is inside the picture. Print a new code if it changes.
