Best Tools to Verify a Remote Employer Is Legitimate (2026)
A curated list of free, real tools to check whether a remote employer is legitimate — company registries, review sites, domain-age lookups, and scam-reporting databases, grouped by what each one actually checks.
Updated July 20, 2026 • Verified current for 2026
The best tools to verify a remote employer, by what they check: business registration (your state’s Secretary of State database, or OpenCorporates for international companies), domain trust (a WHOIS lookup for registration age), employee presence (LinkedIn’s “See all employees” view), reputation (Glassdoor and the Better Business Bureau’s Scam Tracker), and company financials for startups (Crunchbase). No single tool proves an employer is real — use two or three from different categories, since a legitimate company holds up under all of them.
- Company registries confirm legal existence, not that a specific job posting is genuine
- Review sites depend on volume — very new or very small companies may have zero reviews, which isn’t itself proof of a scam
- Domain age alone isn’t conclusive — legitimate small businesses do launch new sites — but a domain under 6 months old paired with other red flags is a strong signal
- Cross-checking two unrelated tools (e.g. a business registry plus LinkedIn) catches most fake postings, because scammers rarely maintain both
Business Registration Lookups
Every legitimate company operating in the US is registered with a state authority. If a company claims to be headquartered somewhere and isn’t in that state’s registry, that’s disqualifying.
Your state’s Secretary of State business search — free, searchable by company name, and shows registration date, status (active/inactive/dissolved), and registered agent. Search “[state] Secretary of State business search” if you don’t have the direct link.
OpenCorporates — a free, open database aggregating company registries from over 140 government sources across 145+ jurisdictions. Useful when the employer claims to be based outside the US, since it searches many countries’ registries from one place without needing to know which state or country registry to check individually. Basic company lookups are free; API access is a paid tier meant for bulk/commercial use, not a one-off check.
Better Business Bureau (BBB) Scam Tracker at bbb.org/scamtracker — a free, searchable database where people report scams by company name. If a company name returns multiple matching scam reports, treat that as a hard stop.
Domain and Website Checks
A WHOIS lookup tool (whois.com, who.is, or ICANN Lookup — any of these work) shows when a domain was registered. Legitimate, established employers typically have domains registered for years; a domain registered in the last few months is a flag worth weighing against everything else you find.
Employee and Reputation Checks
LinkedIn’s company page — click “See all employees” to view current team members. Real companies show multiple employees with complete profiles, work histories, and connections to each other. A company page with zero employees, or only the person who contacted you, is a red flag.
Glassdoor — searchable company reviews and salary data. Look for a mix of reviews across different time periods rather than a handful of recent 5-star reviews (a pattern sometimes associated with fabricated reviews) or a page with zero reviews and heavy recent hiring activity.
TinEye — a free reverse image search tool. Paste the URL of a recruiter’s LinkedIn profile photo or the “team photos” on a company site; if the same image turns up as a stock photo or on an unrelated person’s profile elsewhere, that identity is fabricated. No account needed for a basic web search.
For Funded Startups
Crunchbase — free company profiles showing funding rounds, investors, and leadership. If a company claims to have raised a Series A or B, a legitimate round will show up here, on the investor’s own site, or in press coverage. If it doesn’t appear anywhere, treat the funding claim as unverified.
Frequently Asked Questions
Is there one tool that can tell me if a remote job is a scam?
No single tool covers everything. Company registries confirm a business is legally registered, but not that a specific job offer is real. Review sites show employee sentiment, but new or small companies may have no reviews yet. Use two or three tools from different categories together — a real employer will hold up under all of them; a scam usually fails at least one.
Do I have to pay to verify a remote employer?
No. Every tool in this guide has a free tier that's enough for a basic check — state business registries, OpenCorporates, WHOIS lookups, BBB Scam Tracker, LinkedIn, and Glassdoor are all free to search. Paid tiers (API access, full Crunchbase/PitchBook reports) are for professional research, not needed for a one-time employer check.
What if the company is too new to show up anywhere?
A company with no registration record, no LinkedIn employees, and no web presence isn't automatically a scam — but it is unverifiable, and unverifiable is a reason to slow down. Ask the recruiter directly for the business registration number and verify it yourself before sharing any personal information or accepting payment instructions.
