Legitimate companies really do send people door to door. So do scammers, and the scammers are often better at the doorstep conversation, because the conversation is the product. The good news: legitimacy is checkable, and every check can be done without letting the visit control your timeline.
The core principle: verify independently, never through the visitor
Everything a doorstep visitor hands you, a badge, a brochure, a phone number, a website on their tablet, was produced by the person trying to convince you. A fake company has fake credentials. Real verification goes around the visitor:
- Look the company up yourself. Search the company name plus your city, and read independent reviews on Google or Yelp, not testimonials on the company's own site. A real local business has a footprint: an address, reviews spread over years, a license you can find.
- Check licensing with the actual authority. Contractors, pest control operators, and alarm installers are licensed in most states, and the license boards have public lookup tools. In many cities, door-to-door sellers also need a local solicitor permit. Asking "can I see your permit" is a fair question, and how they react tells you plenty.
- Call the company's published number, not the number the rep gives you. If the rep claims to be from your utility or a known brand, hang up on the porch conversation and call the number on your bill or the official website.
Signs that point toward legitimate
- They accept "not now" the first time, without a script to overcome it.
- They are specific and verifiable: full company name, their own name, a physical local address.
- The offer survives a delay. A real price is still a real price tomorrow.
- They are comfortable with you checking. Legitimate reps deal with verification every day.
Red flags that end the conversation
- Today-only pricing. Manufactured urgency is the single most reliable scam marker, and the FTC flags it specifically in its home-improvement scam guidance.
- "We were just doing work in the neighborhood and have leftover materials." A classic, called out by the FTC by name.
- Cash only, full payment upfront, or pressure to sign now. Legitimate contractors expect deposits and contracts, not your savings on the porch.
- Claiming to be from "the utility company" without saying which one, or asking to see your utility bill. Your bill contains your account number and usage details; it is a data harvest, not a discount check.
- Wanting to come inside to "inspect" something you did not report. Unrequested inspections, especially of roofs and attics, are a common setup for invented damage.
- Vagueness about who they are. No last name, no company address, a website registered last month.
Worth knowing: for many sales made at your home, the FTC's Cooling-Off Rule gives you three business days to cancel, and the seller is required to tell you about that right. A rep who denies it exists has told you what you need to know. Exclusions apply, so read the FTC's current guidance for specifics.
Or skip the doorstep evaluation entirely
The hardest part of all of this is doing it live, at your door, with a trained persuader watching you decide. That pressure is the scammer's whole advantage, and it is the part you can remove.
An EntryVerified sign tells canvassers and salespeople not to knock or ring, and to scan a QR code and submit their offer instead. You receive the company's information and review it on your own time, with every verification tool available and nobody on your porch. Your contact details stay private from the scanner. Legitimate businesses get a real channel to reach you, and the ones who only work under pressure lose their leverage. The sign is free for homeowners.
The short version
Legitimate reps survive independent verification and a 24-hour delay. Scammers need urgency, cash, and your front porch. Verify around the visitor, never through them, and if you would rather not run this evaluation at your door at all, move the interaction to a channel you control.
