How it works

This project aims to make it very easy for local communities to set up a system for community members to prove to event organizers and businesses that they have received a Covid-19 vaccine. Below are our how-to-use steps for both reciepients of the vaccine and organizers who want to check for proof of vaccination.


Step 1: Request a QR code from an "issuer"

Have you been asked by an event organizer or business to show proof that you've been vaccinated?
If so, they may have linked you to this website and asked you contact a specific "issuer" or "group" of issuers that they trust to verify you've been vaccinated.
Simply call, email, or visit the website of the issuer you want to get a QR code from, and they will verify that you have received you Covid-19 vaccine.
(NOTE: issuers may ask you for additional proof, like showing your vaccine record card)

Step 2: Get issued a vaccine verification QR code

Once the "issuer" has verified you've received a Covid-19 vaccine, they will generate a QR code and give it to you.
You'll get your QR code via email, text, or they may even print it out and hand it to you (if you're getting issued a QR code in-person).
You can save this QR code wherever you want and make as many copies of it as you like.
NOTE: Your QR code contains your name and possibly some other personal information (depending on the issuer). Scan your QR code to see what it has in it.

Step 3: Show you QR code as proof of vaccination

Once you have your QR code, you can email, text, or show the QR code in-person to the event organizer or business that originally asked for it.
NOTE: It's up to the event organizer or business owner to decide which "issuers" they will trust, so check with them to see if your issuer is one they trust.

Step 4: Event organizer or business scans your QR code

When you send or show your QR code to the event organizer or business that asked for proof, they must scan it.
They will make sure they trust the issuer and make sure you are the person listed in the QR code (usually by checking your ID).


Step 1: Find "issuers" you trust

Browse the "issuer" and "group" of issuers directories and see if there's anyone you trust to correctly issue QR codes to vaccinated people.
If you don't find anyone you trust, you can become your own issuer and generate QR codes yourself to people you know have received a Covid-19 vaccine.

Step 2: Ask people to get a vaccination verification QR code

If you have in-person gathering where everyone needs to be vaccinated, ask people to get a QR code from one of your trusted issuers or groups from Step 1.
You can link directly to the specific issuer or group by clicking on that issuer or group's name and copying the url (e.g. "https://vax.codes/issuers?id=some_id").

Step 3: Scan QR codes

Before your in-person gathering, attendees can email, text, or show you their vaccination verification QR codes.
Scan them using our scanner page (should work on any mobile phone) or use any QR code scanner app and open the scanned link in a web browser.
If you don't have a camera, no worries! If you have an image file of the QR code, you can just upload it directly on our scanner page (click "Upload an image...").

Step 4: Verify the scanned results

When you scan a QR code, it will show the contents included in the QR code and list the "issuer" and any "groups" that issuer is in.
VERIFY THE QR CODE CONTENTS MATCH THE PERSON'S ID
MAKE SURE THE ISSUER AND/OR GROUPS ARE ONES YOU TRUST
Anyone can become an issuer of QR codes, so only trust the specific issuers and groups you picked out in Step 1.
If you have any questions about the validity of a QR code, contact the issuer listed at the bottom of the scanned QR code.
