Frequently asked questions
I already have a "No Soliciting" sign — how is this different?
A sign broadcasts "no" to whoever happens to look at it. NoKnock makes that "no" checkable: your address is registered, so a canvasser using the app can check before they knock rather than guess from the doorstep. Two things a sign can't do — you choose which visits are still welcome (leave youth fundraisers on while solar and pest control stay blocked), and if someone knocks anyway you end up with a timestamped record instead of just your word against theirs. The decal itself still does the same job a good sign does: most solicitors read it and move on.
I have a video doorbell. Do I need this too?
They do different jobs, and they work well together. A camera tells you someone came to the door — after they're already standing there. The decal is aimed at the knock not happening in the first place. Where the camera earns its keep is afterward: if someone ignores the decal, a screenshot of them at your door is exactly the kind of thing that makes a report solid.
Is NoKnock legally enforceable?
NoKnock is a registry and signal system, similar in spirit to the Do Not Call Registry. It clearly communicates that solicitation isn't welcome at your address. Enforceability depends on local ordinances, many of which already restrict solicitation at residences that have posted a no-soliciting notice — NoKnock simply makes that notice visible, verifiable, and easy to check.
How much does it cost for homeowners?
Registering your address is completely free — and you can print your own "Do Not Knock" decal at home at no cost. A professional weatherproof decal mailed to your home is available as an optional paid upgrade.
Can I earn a free weatherproof decal?
Yes — by inviting neighbors. Your dashboard has a personal invite link, and when 3 neighbors in your area register through it and each stays registered for 14 days, we mail you a weatherproof decal free. Your dashboard shows a row of four houses — yours and three invites — that light up as neighbors join, and a set of badges you earn along the way — some for neighbors you bring in, some for your block filling in around you — which you can share as a card if you like, though nothing is posted unless you choose to. One free decal per account, we review each reward before it ships, and you only ever see counts — never which neighbors joined. Buying a decal in the meantime doesn't affect the free one.
Is there a NoKnock app?
Not yet for homeowners — a phone app is on the way, and it isn't out while it's with Apple and Google for review. Nothing is waiting on it: noknock.co works on a phone browser, so you can register, print your decal, set your preferences and report a knock from the same screen you're reading this on. The separate app canvassing teams use to check the registry is going out to organizations we onboard directly, not on the app stores yet either.
I live in an apartment or condo — can I register my unit?
Yes. There's an Apt / Unit field when you register or edit an address, and if you pick your address from the suggestions and Google knows your unit, it fills in automatically. Two households in the same building can each register their own unit. Your unit also rides along on the shipping label, so a weatherproof decal ordered for "1725 Main St, Apt 3" actually arrives at Apt 3. If you registered before the field existed, edit the address from your dashboard and add it.
Will my HOA let me put this up?
Usually not an issue, though your association's rules are the final word. Most HOA signage restrictions are written about yard signs and window signs visible from the street — a decal on your own front door or storm door is a different thing, and typically isn't what those rules are aimed at. If you're unsure, your CC&Rs are worth a skim before you order the weatherproof version. The printable decal is free either way, so there's no cost to trying it first. If you're on the board yourself — or your association keeps fielding complaints about door-to-door sales — an association can cover decals for every resident who wants one. See NoKnock for HOAs.
Can I block specific industries but allow others?
Yes. When you register, your home is marked "Do Not Knock" for every category by default. From your dashboard you can allow back any categories you're fine with — for example, leaving youth fundraisers (Girl Scouts, school sports teams) welcome while keeping solar, home security, and pest control blocked.
What happens when someone scans my QR code?
It depends who's scanning. A canvasser using the NoKnock app gets a yes-or-no answer for their industry and the time of day — never your preferences themselves. Anyone else scanning from a phone camera sees that it's marked Do Not Knock, along with your street and city and most of your house number blocked out — enough to confirm the decal belongs to that door, not enough to pinpoint the house from a photo. Either way, no name, no email, and no list of what you've blocked. Blurring the code before posting a photo of your decal online is still worth doing.
What if a canvasser ignores my sign anyway?
You can report it in seconds from your dashboard. We ask who it was — a company name if they gave one, and “I don't know” is a perfectly good answer. If they left a flyer, a photo of it names them for you. A description is optional. Your report becomes a timestamped record: yours to keep, so it's never just your word against theirs, and ours to spot patterns in. One report is a bad afternoon — the same company turning up across a neighborhood is something we can take to them. We don't promise to chase each report individually, and we'd rather say so than pretend otherwise. See our homeowner tips for more on getting the most out of your registration.
How do canvassing organizations use NoKnock?
Organizations sign up, get an invite code for their canvassing team, and can check the registry before knocking on a given door. This saves their team time and helps them focus on addresses where someone is actually open to a conversation.
Can I have multiple addresses registered under one account?
Yes — if you own more than one property, you can register and manage all of them from a single NoKnock account.
Can two people in the same home each have their own login?
Yes. Whoever registered the address can add up to four other people from the dashboard — enter their email and they get a link to accept, good for 14 days. They can sign in however they like when they open it; it doesn't have to match the address you sent it to. Everyone in the household sees the same address, can set which canvassers are turned away, can report anyone who knocks anyway, and gets the "someone checked your sign" alert on their own phone. Editing the street address and deleting the registration stay with the person who registered it.
Can I remove my address from the registry later?
Yes, you can deactivate or remove any registered address at any time from your dashboard.
