Track postcard QR codes without confusing scans and sales

What does a postcard QR code actually measure?

A scan measures a visit through one specific link, nothing more. It does not tell you how many people read the card, kept it on the fridge or typed your address by hand instead. It does not prove that the card caused a later purchase. Repeated scans, shared links, browser privacy settings and analytics consent can all change the counts.

That is why the most useful reports keep three numbers apart: visits from the tagged link, inquiries or leads, and completed sales or bookings. Each one answers a different question, and merging them is how campaigns get overstated.

Tracking also misses people. Some readers call instead of scanning, walk in with the card, or search for your business name after seeing it. Those responses are real but will not appear under the tagged link unless you ask for them. A short question at booking, such as how did you hear about us, fills part of that gap.

How do you set up tracking for a postcard QR code?

Start with the destination. Choose a landing page that matches the offer on the card, not your homepage. Then add campaign tags. Google Analytics says to always use utm_source, utm_medium and utm_campaign, and it treats values as case sensitive, so choose lowercase names and record them in a register. The campaign link builder adds the three core tags to your URL in the browser.

Next, create a short address on your own domain that redirects to the tagged URL, and generate the QR code from that short address. Short addresses keep the code less dense and let you change the destination later without reprinting. Finally, print the short address beside the code so people who prefer typing are still counted.

Which metrics should you report?

Report each metric against the number of cards distributed, and keep the cost next to it.

Worked example, using illustrative numbers only: 1,000 cards mailed, 40 tagged visits and 5 bookings give a visit rate of 4 percent and a booking rate of 0.5 percent per card. These figures are not a benchmark for any industry.

How do you connect scans to sales?

Visits live in your analytics tool, while sales usually live in a booking system, point of sale or spreadsheet. Link them with something the customer uses naturally, such as a postcard offer code, a dedicated booking page or a question at checkout. Record the date so you can apply a fixed observation window, for example the four weeks after the in home date.

Remember that some people who redeem the offer would have bought anyway. If you need to estimate how many sales the card truly added, compare against a group that did not receive it. The guide to postcard A/B testing explains how to set up a fair comparison.

How do you test the full tracking path before printing?

A code can scan perfectly while the attribution fails. Scan the printed proof with more than one phone, follow every redirect and complete the intended action with a test booking or form. Check that the tags are still present on the landing page, that the visit appears in analytics under the right campaign and that the test record reaches your sales system.

• Scan the printed proof on at least two phones.
• Confirm the redirect keeps the campaign tags.
• Complete a test inquiry or booking end to end.
• Check that the visit appears under the correct campaign.
• Record the number of cards mailed and the mailing date.
• Delete or label test records before reporting.

How long should a postcard tracking link stay live?

Longer than the campaign. Postcards stay on counters and fridges for weeks, and some are found months later. Keep the short address and redirect working, and when the offer ends, point it at a page that explains the offer has ended and suggests the next best step. An error page wastes the attention the card earned.

What should you do with the results?

Set the review date before launch and stick to it. Looking at results every day invites decisions based on the first few responses, which are rarely representative. Compare cost per outcome with the value of a new customer, and use the campaign break even calculator to see how many incremental orders the mailing needed to cover its cost. Keep the report with the artwork, the list or route used and the mailing date so the next campaign starts from evidence rather than memory.

If you plan to mail to every household on a route rather than a list, direct mail postcards arrive addressed and bundled for Every Door Direct Mail, with postage paid separately. For more on naming and tagging conventions, read UTM links for print campaigns.
