Fake open house sign-in info — and how to stop it.

Fake sign-in info happens because nothing on a paper sheet or basic form checks that the phone number is real — the fix is verifying it at the door, before it becomes a contact.

The short version

Paper sheets, Google Forms, and most sign-in apps all share one hole: they record whatever is typed, real or not.
The fix is verification at the door — a code texted to the phone; wrong number, no confirmation, no contact.
Verification proves a number is real and reachable — it can't prove identity, and no doorway tool honestly can.

01 Why verification exists

555-1234, "asdf@gmail," and a wasted follow-up.

Plenty of agents have walked out of an open house holding a sheet full of numbers that go nowhere. That's the whole reason verification is built into Tycoda.

You know the drill: a clipboard by the door, a pen on a string, and a page of handwriting you can't read next to numbers that ring a disconnected line. You spend Monday chasing ghosts. It doesn't matter whether it's paper, a Google Form, or a slick QR app — if the tool simply stores what was typed, it can't tell a real mobile from a fake one. Same hole, nicer paint.

02 The fix

Verify at the door, not later.

The fix is simple and it happens in the moment: the visitor confirms a one-time code texted to their phone. A wrong number never gets the code, so it never becomes a contact.

Visitor scans the QR and enters their name, email, and mobile number.
Tycoda texts a one-time code to that number.
They enter the code — and in return get the digital flyer and property info. That's the value exchange that makes a real number worth giving.
Only confirmed numbers land in your dashboard. The scribble and the fake digit simply never arrive.

What you own

Every verified visitor is yours — exportable to CSV or synced to your CRM. Free for agents, whether or not the open house is ever sponsored.

03 The honest part

What verification can and can't do.

It's worth being precise about this. Verification proves a phone number is real, reachable, and in the visitor's hand right then. That kills the fake-number problem that wrecks open-house follow-up — which is the problem that actually costs you time.

What it can't do is read minds. It doesn't guarantee someone's identity or their timeline, and no doorway tool honestly can. Someone could still verify a real number and not be ready to buy for a year. That's fine — you'll know it's a real person you can actually reach, which is worlds ahead of a page of guesses.

Do open house sign-in apps verify phone numbers?

Most don't. The majority of sign-in tools — paper sheets, generic form apps, QR forms — just record whatever is typed. They never send a code and never confirm the number belongs to the person in the room, so a wrong or fake digit sails straight through. Tycoda is built the other way around: the number isn't accepted until a texted code is confirmed.

Why do visitors give fake info in the first place?

Usually to avoid being called forever, sometimes just reflex at a clipboard. It isn't malice — it's friction with no payoff. Tycoda changes the trade: verifying unlocks the digital flyer and property info the visitor actually wants, so there's a reason to give a real number instead of scribbling 555-1234.

Can't someone still enter a real number that isn't theirs?

Verification proves the number is real and reachable and that whoever signed in can receive a code on it right then. It can't read minds — no system can guarantee identity from a doorway. What it does guarantee is that a fake or wrong number never becomes a contact, which is the failure that actually plagues open houses.

Is a paper sign-in sheet still worth using?

As a courtesy log, sure. As a source of reachable contacts, it's the weakest option — nothing on paper is verified. If you want a good free printable to start with, there's one on the template page, with an honest note about its ceiling.

Stop collecting numbers that go nowhere.
