Google Review QR Codes: Where to Put Them So People Actually Scan

What a review QR code does

A Google review QR code is a square barcode that opens your Google review form when a customer points their phone camera at it. No app needed. One scan takes them directly to the place where they write a review on Google.

The goal is simple: remove friction. Instead of asking a customer to remember your business name, search Google, find your profile, and click "Write a review," you hand them a printed code they scan in three seconds. The review form appears on their screen.

This works because most customers have their phones with them at the moment they're happiest—right after a good haircut, meal, or repair job. A QR code captures that moment.

You need your Google Place ID first. This is a unique identifier Google assigns to your business profile.

Find it here:

1. Go to Google's Place ID Finder.
2. Search for your business name and address.
3. Copy the Place ID from the result.

Alternatively, open your Google Business Profile dashboard, go to the "Ask for reviews" card, and copy the short review link it provides.

Once you have the link, use any free QR code generator (Google's own QR code generator, QR Code Monkey, or similar). Paste your review link, generate the code, and download it as a PNG or PDF.

LinkToReview includes a free QR code that opens your review page. You can print it immediately on receipts, table tents, invoices, or counter signs.

Where scans actually happen: placements by business type

Placement matters more than the code itself. Put it where customers are calm, have their phone in hand, and have just experienced your service.

Restaurants and cafes

Print the code on receipts. Customers see it while paying or waiting for change. This is the highest-intent moment—they just ate.

Also place a 4x4 inch sign on the table, near the check holder or condiment caddy. Diners waiting for the check have time and their phone nearby.

For counter service, put a small sign (2x2 inches) next to the register or on the counter where customers stand. They see it while waiting to pay.

See QR codes for restaurants for detailed placement strategy.

Auto repair shops

Place a 3x3 inch sign on the customer waiting area desk or on the wall behind the counter at eye level. Customers waiting for their car to be ready have 30 minutes to an hour and nothing to do.

Print the code on the invoice or work order. Customers see it when they pick up their car and pay.

Put a small sign (2x2 inches) on the service writer's desk. If they hand the customer a printed estimate or receipt, the code is right there.

Salons and spas

Print on receipts. Customers see it at checkout after a service they just enjoyed.

Place a 3x3 inch sign at the front desk or near the payment area. Customers stand there for 30 seconds to a minute.

Put a small code on appointment reminder cards or thank-you cards sent after the visit. This reaches customers when they're at home and satisfied.

Home services (plumbers, HVAC, electricians, contractors)

Print the code on the invoice or final bill. Customers see it after the work is done and they're ready to pay. This is the moment they decide if they're happy.

Leave a printed card (business card size or 2x3 inches) with the code on the job site or hand it to the customer as they leave. Make it easy to scan before they forget.

Include the code in follow-up emails or text messages sent a day or two after the job. Customers are less likely to scan immediately, but a reminder works.

See QR codes for home services for contractor-specific tactics.

Medical and dental offices

Print on the checkout receipt or patient statement. Patients see it as they leave.

Place a sign in the waiting room near the exit. Patients have time while waiting and may scan before they leave.

Include the code in appointment confirmation texts or emails. Patients can scan and review at home.

The sign copy that works

The code alone is not enough. Add a line of text that tells customers why they should scan.

Use one of these:

"Scan to leave a Google review. Takes 30 seconds."

"Help us out. Scan to review on Google."

"Love us? Scan to leave a review."

"Your feedback matters. Scan to review."

"Had a great experience? Scan to review on Google."

Do not offer incentives. Google prohibits offering money, discounts, gifts, or free services in exchange for reviews. Ask everyone the same way, regardless of whether you expect a positive or negative review. This is Google's review gating policy.

Keep the text short. Customers scanning a code are in a hurry. One sentence is enough.

Print sizes and contrast

Size depends on placement and distance.

Counter signs and table tents: 3x3 inches to 4x4 inches. Customers stand or sit within arm's reach.

Wall signs in waiting areas: 4x4 inches to 6x6 inches. Customers view from 3 to 6 feet away.

Receipt codes: 1x1 inch to 1.5x1.5 inches. Customers hold the receipt in their hand.

Business cards or leave-behinds: 1x1 inch to 2x2 inches.

Contrast is critical. Use a black QR code on a white or very light background. Avoid colored codes or backgrounds that reduce contrast. Phone cameras read high-contrast codes faster and more reliably.

Test your code before printing. Use your own phone to scan a printed sample from different distances and angles. If it takes more than two attempts, the size or contrast needs adjustment.

Track what's working

You cannot see which scans came from which QR code using Google Business Profile alone. But you can track overall review volume and timing.

Check your Google Business Profile dashboard weekly. Note the number of new reviews. If you place a code on receipts on Monday and see a spike in reviews by Wednesday, that placement is working.

Rotate placements. Try the code on receipts for two weeks, then move it to a table sign. Compare review counts. This tells you where customers are most likely to scan.

If you use the complete playbook for review generation, you'll track multiple tactics at once. QR codes are one part of a broader strategy.

Note the timing of scans indirectly: if you place a code in your waiting room and reviews arrive within hours, customers are scanning on-site. If you place a code on an invoice and reviews arrive a day or two later, customers are scanning at home.

Key takeaways

• A Google review QR code removes friction by opening the review form in one scan. Place it where customers are calm and have their phone in hand.
• For walk-in businesses, put codes on receipts, table tents, and counter signs. For field-service businesses, print them on invoices and leave-behind cards.
• Pair the code with one short line of text explaining why customers should scan. Do not offer incentives or ask only satisfied customers—Google prohibits both.
• Print at 3x3 inches or larger for wall signs, 1x1 to 1.5x1.5 inches for receipts. Use black on white for maximum contrast and scannability.
• Track results by monitoring review volume and timing in your Google Business Profile. Rotate placements to find what works best for your business.
