Open House QR Code: How to Set One Up and Where to Put It
What the QR code should actually link to
The most common mistake is pointing the code at something a visitor could have found on their own — your website, your agent profile, the Zillow listing. All of those are places they can reach later, from the car. A code at the door has exactly one job: record who walked in, while they are standing in front of you with their phone already out.
So it should open a short form that already knows which house it is. The visitor should type their own details and nothing else. If scanning it produces a page where they have to search for the address, pick the right listing, scroll past a hero image, or create an account, you have lost them on the doormat — and you have lost them in front of the seller.
- Opens straight in the phone's browser — no app to install, nothing for the visitor to sign up for
- Already carries the address and date, so the visitor fills in only their own information
- Asks for the fewest fields you will genuinely act on
- Includes the consent line, which is what makes the follow-up list usable rather than awkward
- Shows a confirmation, so the visitor knows it worked and does not sign twice
How to set one up for a specific open house
- Decide what the form asks. Name, one contact field, whether they are already working with an agent, and consent. Every extra column costs you completions.
- Create the destination — a sign-in page tied to this address and this date, not a generic contact form. On ShowingMarket you create a sign-in sheet and the QR code is generated with it; that needs a free account, because the sheet belongs to one specific open house. The printable templates need no account at all.
- Point the code at that URL. Any generator will do if you are building your own; what matters is that the URL is short and stable, because a long one makes a dense code that scans badly in poor light.
- Test it on two phones, not one. Use your own and borrow a colleague's — different camera, different operating system, different age of hardware.
- Print the code, and print a paper sheet as backup. The backup is not pessimism; see the scanning section below.
How big to print it, and where to put it
Roughly two inches square is enough for someone scanning at arm's length from a table. If the code is on a door, a window or a yard sign — anywhere people scan from several feet away — go bigger, four inches or more. Keep the white margin around it, keep the contrast high, and resist shrinking it to fit a design: a code that has to be re-framed twice gets abandoned.
| Where you put it | What actually happens |
|---|---|
| Stand on the entry table | The default, and the best one. Visitors already expect a sign-in moment there, and you are usually standing beside it to point at it. |
| Taped to the door glass | Gets scanned before they walk in — but people arrive in twos and threes, and the first person blocks it for everyone behind them. |
| Kitchen island or counter | Works well if that is where you greet people rather than the entry. A second code costs nothing, so put one in both places. |
| Inside the flyer or brochure | Scanned later, in the car or at home, if at all. That is a different and much weaker moment than standing in the hallway. |
| On the yard sign | Catches drive-by traffic who never come in. Low intent, but it costs nothing and occasionally surprises you. |
When a phone won't scan
It happens often enough to plan for. The usual causes are a dim entryway, glare on glossy paper, a code printed too small, an older phone camera, or simply no signal — basements and newer builds with foil-backed insulation are both notorious for it.
The single highest-value habit is printing a short URL underneath the code. Anyone can type a web address; nobody can debug a camera in front of a seller. Beyond that: matte paper rather than glossy, put a lamp on it if the entry is dark, and keep the paper sheet on the table. A visitor who cannot scan and finds nothing to write on simply walks past, and you never know it happened.
What happens to the contacts afterwards
A QR sign-in removes the transcription step, not the follow-up. Entries arrive typed and legible, which means the job that used to eat Sunday evening — squinting at handwriting and guessing whether that character is an a or an o — disappears. What remains is the part that was always the point.
Same evening, ideally: give the seller the visitor count and any feedback, because that is the report they are actually waiting for. Follow up the people who ticked consent while you can still put faces to names. Keep the record of who entered the home. Follow-up sent within a day reads as attentive; the same message on Wednesday reads as a mailing list.
Do you still need a paper sheet?
Yes — as backup, not as the primary. Print a few, leave them beside the code, and you have covered the dead-signal basement and the visitor whose phone is at four percent. The fuller argument for running both, and what each one is actually better at, is in paper sign-in sheets vs. QR codes. If you just want the printable files, they are on the free sign-in sheet templates page, and the QR version lives on open house sign-in.
