Google review QR codes: how to make one and where to put it (van, invoice, card)

A Google review QR code is a square people scan with their phone camera to land on your review form. To make one free, paste your Ask for reviews link or Place ID into our review link generator, download the code as PNG or SVG, and print it where customers will see it. The generator needs no sign-up and adds no watermark.

Below: how to make one, how big to print it, and where it works for a tradesman.

How to make a Google review QR code

With the free generator. Open the review link generator, pick your business, and download the code. Choose SVG for anything big, such as a van sticker, because it stays sharp at any size. PNG is fine for invoices and cards.

From Google. On a computer, open your Business Profile, choose Read reviews, then Get more reviews. Google shows a QR code you can save. Google says these codes can only be made from a computer browser, not a mobile.

Whichever route, the code should point straight at Google. A code that goes through someone else's redirect link can die if that company shuts down or starts charging. Ours points directly at Google, so it keeps working whatever happens to getmitch.

Before you print anything: scan it with your own phone and check it lands on your review form. If you have a similar name to another firm nearby, check it is the right one.

How big to print it

For anything seen from a distance, use a rule of thumb: 1 cm of code per 10 cm of scanning distance. Someone scanning from 3 metres wants a code about 30 cm wide.

Then the basics:

• Dark ink on a light background. Do not invert it or put it on a photo.
• Leave a clear blank margin round the edge, roughly the width of four of the little squares.
• Do not stretch it, round the corners or put a logo over the middle unless you have tested it.
• Add a few words next to it: "How did we do? Scan to leave a Google review." People do not scan an unlabelled square.

Where to put it

On the van

Rear doors are the best spot. People stop behind you at lights and in traffic, they have nothing else to look at, and a van that is parked outside a house tells the neighbours who did the work. Make the code big, give it a white border and keep the words short.

A few cautions. Nobody should scan a code while driving, so treat the van as the thing that makes people remember you, not as the thing they scan on the move. A parked van on a driveway is a better scanning moment than one at a roundabout. Check your wrap or sticker supplier will print it large and at high contrast. If your van carries a lot of text, the code gets lost, so give it space.

On invoices

Put it at the bottom, next to the line that says thanks. The customer is on that page when they decide whether to pay, and they are already holding a phone. A note like "Scan to leave us a Google review" is enough.

On business cards

Small but worth it, particularly if you hand cards to people at quotes who did not hire you but know someone who will. Keep it at least 2 cm wide.

On job sheets and certificates

Hand the customer their copy and point at the code. For gas and electrical work that comes with paperwork, the code can go on the cover sheet or the covering email. Do not alter or print over any compliance certificate or form; add it to your own cover page.

Review request cards

A small printed card left on the worktop or handed over at the door. Keep it simple: your logo, one line, the code. A card on its own does not get much action, but paired with a text a day later it reminds people.

On your website or email signature

A QR code is no use on a screen someone is already using on their phone. Use the plain link there instead. See how to find your Google review link.

The sticker problem

The most common mistake is printing 500 cards before checking anything. Do a test run:

1. Print one on your office printer at the size you plan to use.
2. Scan it with two different phones, one older.
3. Scan it in poor light and from the distance you expect.
4. Only then order the batch.

Rules to keep to

The code is only the delivery. Google's rules apply to how you use it:

• Do not offer anything in return for a review, whether that is a discount, a prize draw or a free service. Google strictly prohibits it.
• Do not use the code only with customers you think will be happy. Google's policy says not to selectively ask only happy customers.
• Do not ask your staff or family to scan it and leave reviews.

In the UK, fake reviews and reviews with a hidden incentive have also been a banned practice under the Digital Markets, Competition and Consumers Act 2024 since 6 April 2025 (see the CMA's guidance). This is general information, not legal advice.

Pair the code with a text

A QR code catches the customer who is looking at the invoice. A text catches the one who has gone home. Doing both is the point. The text comes a day or two after the job, with the link. The code backs it up. Our guide to getting more Google reviews puts the full routine together, and how to ask for a Google review has the words to use.
