Google Review QR Code Generator

A review QR code is a picture of one link

A static QR code holds nothing but the text of a link, drawn as squares. There is no tracking, no redirect and no account behind it. That is the good news (it cannot expire or be switched off by a vendor) and the whole risk: if the link is wrong, every printed copy is wrong, forever.

Our take: test the link before you print 500 cards. The QR step takes seconds; the print run is the expensive step, and a code cannot be edited after it is on paper. Open the link on a phone, check that the review form names the right business at the right address, then print one proof and scan it with a different phone. Only then order the batch.

Google also gives you a QR code of its own. When we read Google's help page on requesting reviews, the steps were: open your Business Profile, select Read reviews, then Get more reviews, and copy the link or download the QR code, and the page said review QR codes could only be generated in a computer browser, not on mobile. If you manage the profile, that is the most direct route. This tool covers the cases it does not: an agency building a code for a client without Profile access, a vector (SVG) file for a print shop, a Maps link or Place ID you already have, and a card that is ready to print. If you only need the link and message templates, use our review link tool.

How big does a Google review QR code have to be?

Size is set by the link, not by the tool. A QR code is a grid of small squares called modules, and each step up in version adds 4 modules per side (Denso Wave: version 1 is 21 by 21, version 40 is 177 by 177). A longer link, or a higher error correction level, forces a higher version, which means a denser grid, which means smaller squares at the same printed size. Small squares are what fails when someone scans a code on a crowded counter.

We ran the generator in this page against a real-length review link, https://search.google.com/local/writereview?placeid= followed by a 27-character Place ID (79 characters in all), at each error correction level:

Computed 30 October 2026 with the qrcode-generator library this tool uses, in byte mode, for the link https://search.google.com/local/writereview?placeid=ChIJN1t_tDeuEmsRUsoyG83frY4. The 0.5 mm module and the 4-module margin are our working assumptions, not a standard: Denso Wave's page on the code area states that QR Code requires a four-module wide margin on all sides, so the 4-module margin is theirs. The 0.5 mm module is our own working assumption, not a standard. The printer floor uses Denso Wave's recommendation that each module be made of 4 or more printer dots, at 300 dpi (4 dots is 0.34 mm). The scanner limits on Denso Wave's module size page (about 0.1 to 0.25 mm per module) are for its own scanner models, not for phone cameras, so we do not use them. Treat all of it as a floor and test your own print.

Three things stand out. L and M are the same size for this link, so the extra damage tolerance of M costs nothing; the page defaults to M. Denso Wave's error correction page gives about 15% for M and about 25% for Q (we could not read its figures for L and H). Going from M to H makes the code 32% wider and 75% larger in area (49 modules against 37), so at one fixed printed width each square shrinks by about a quarter. And the shorter the link, the bigger the squares: an illustrative g.page link with a 16-character code (a placeholder, real codes vary) comes out at version 3, 29 by 29 modules at M, so at the same 30 mm printed width (margin included) its squares are about 22% larger than the writereview link's. We could not confirm from Google's help page what the link it generates looks like, so check its length: if it is shorter than the writereview link, it is the better thing to encode.

On an A6 table card (105 by 148 mm) none of this is tight. A code printed 40 mm wide, margin included, gives about 0.89 mm per module at M, nearly twice our floor. The size rule only bites on stickers, receipts and business cards, which is where to test hardest.

How to create, print and place your Google review QR code

1. Get the right link. Open the business itself on Google Maps and copy the full address from the browser bar, or copy the link from your Business Profile, and paste it into the box above.
2. Choose M unless the code will live on something that gets scuffed. Check the readout beside the code for the version and the smallest safe print size.
3. Download the PNG for documents and screens or the SVG for a print shop (it stays sharp at any size). Or press Print A6 card and set the paper to A6 with no margins; on A4, print it at 100% and trim.
4. Print one proof, scan it with two different phones and confirm the form shows your business name and address.
5. Place it where people already pause: the till, the table, the handout that goes in the bag, the invoice. Keep the line under it factual. "Scan to leave a review" is enough.

What Google's rules mean for the card

Asking for reviews is allowed. Google's user-contributed content policy says merchants may solicit genuine reviews, without offering incentives to do so. In the wording we read, a merchant may not offer incentives such as payment, discounts, free goods or services in exchange for a review, may not "selectively solicit positive reviews from customers", and should not "require or pressure users to leave ratings or write reviews while on the premises". The same page says merchants should not request that specific content be included.

• The line under the code stays neutral. This tool blocks captions that mention a discount, a freebie, a prize or a number of stars, because incentives and selectively soliciting positive reviews are what the policy rules out.
• One code for everyone. Put it on the table card, not only in the message you send to customers you expect to be happy.
• Do not stand over the scan. A code on the counter is an invitation. A staff member waiting for the phone to be raised could read as the on-premises pressure the policy warns about.

The printed code points at a listing, so check the listing

A QR code on 500 cards is a permanent pointer to one record in Google's database. If that record is a duplicate, carries an old phone number or is one you do not control, the cards keep sending reviews there. Our free NAP checker is a small sample, not a survey: 99 anonymous scans since 4 September 2026, the business found in 83 of them, an average score of 85 out of 100, and at least one mismatch between what the owner typed and what a public source showed in 42% of them (phone 25%, address 22%, name 10%). Run it before you print, and see the review guide for the checks that matter once the cards are out.

Reviews are one job; keeping your name, address and phone the same everywhere your business is listed is another, and that is what our citation building service takes care of.
