No single check proves that a company is legitimate. Registers can be out of date, addresses change, and a well-presented website tells you about presentation rather than performance. Verification works because signals accumulate: when several independent sources describe the same business in the same way, confidence is reasonable. When they do not, you have something specific to ask about.
The ten checks below are ordered roughly the way an investigation tends to run — from establishing who the entity is, to testing whether the surrounding picture supports it. Work through them before money moves, before goods ship, and before you make a commitment to someone else that depends on this company performing.
1. Confirm the legal company name
What to check. Ask for the full registered name, not the trading name on an invoice, email signature or website footer, and look it up on the relevant company register.
Why it matters. Contracts, payments and any later recovery attach to a legal entity. A trading name on its own does not identify who you are actually dealing with.
What an inconsistency may mean. Many businesses trade under a name that differs legitimately from their registered one. What warrants a question is when nobody can tell you the registered name, or the name given belongs to a different entity than expected.
2. Verify the registration number
What to check. Check that the number you were given resolves on the register to the same company, in the same jurisdiction, that you believe you are dealing with.
Why it matters. The registration number is the one identifier that is unambiguous within a jurisdiction. Names can be similar; numbers usually are not.
What an inconsistency may mean. A number that returns a different company, a dissolved entity or nothing at all may be a transcription error — or it may mean the details were assembled rather than taken from the register.
3. Check company status
What to check. Confirm whether the company is active, dormant, in an insolvency process, dissolved or struck off, where the register publishes that information.
Why it matters. Status affects whether the company can trade and whether an obligation is likely to be met. It also shapes what your options are if something goes wrong.
What an inconsistency may mean. A status that conflicts with how the company is presenting itself — trading actively while shown as dissolved, for example — is a significant inconsistency and worth resolving before committing.
4. Compare the registered address
What to check. Compare the address on the register with the address used on correspondence, invoices, the website and any premises you have been told about.
Why it matters. Addresses connect a company to a place. Consistency across sources suggests a settled operation; a fragmented picture suggests the opposite.
What an inconsistency may mean. Registered offices are frequently accountants' or agents' addresses, which is entirely normal. The question is whether the operational address is verifiable at all, and whether it fits the size and type of business described.
5. Review directors and officers where available
What to check. Where a jurisdiction publishes them, check the named directors or officers and compare them with the people you are dealing with.
Why it matters. It tells you whether the individuals negotiating, signing or requesting payment have any published connection to the entity that will be bound by the agreement.
What an inconsistency may mean. Not every jurisdiction publishes officer data, and authorised employees are not directors. What matters is whether there is any verifiable link between the people and the company, and whether the answers you get are consistent.
6. Verify the company website
What to check. Check that the website describes the same entity: the same legal name, the same registration details where required, contact routes that work, and content consistent with the business you were told about.
Why it matters. A website is the most public statement a company makes about itself and is easy to compare against registry information.
What an inconsistency may mean. Missing company details, contradictory descriptions, or a site that appears unrelated to the stated activity do not prove anything on their own, but they weaken the picture rather than support it.
7. Review the domain and wider digital footprint
What to check. Look at the domain used for email and the website, whether it belongs to the company itself, and whether the supporting technical signals are consistent with a business of the stated type.
Why it matters. Communications and payment instructions arrive over this infrastructure. Its characteristics form part of the overall picture.
What an inconsistency may mean. A very recently registered domain, or free consumer email used for significant commercial correspondence, can be perfectly innocent for a new business — but it should be read alongside claims of a long trading history.
8. Check sanctions and relevant compliance signals
What to check. Screen the company and, where known, the individuals against applicable sanctions and restriction sources relevant to your jurisdiction and the transaction.
Why it matters. Exposure here is independent of whether the commercial deal performs, and it may carry obligations for your business.
What an inconsistency may mean. Name-based screening produces similar-name matches that require confirmation against additional identifiers. A possible match is a prompt to verify carefully, not a conclusion.
9. Compare contact details with independent information
What to check. Verify phone numbers, email domains and payment instructions against details you obtain independently rather than only those supplied to you.
Why it matters. Contact and payment details are the most commonly manipulated part of a transaction, and the point at which a loss becomes hard to reverse.
What an inconsistency may mean. Late changes to bank details, accounts held in a different name or country to the counterparty, or urgency around payment all warrant independent confirmation through a channel you sourced yourself.
10. Look for inconsistencies across the whole picture
What to check. Step back and read the findings together rather than as a list of individual results.
Why it matters. Most problems are visible in the relationships between details, not in any single detail. A picture that fits is reassuring; a picture that requires several separate explanations is not.
What an inconsistency may mean. One explainable anomaly is common. Several unrelated anomalies pointing the same way is the pattern worth acting on — by asking questions and requesting evidence before you commit.
The most important check is consistency
Each of the ten checks above can be passed by a business that is entirely genuine, and any one of them can produce an awkward result for reasons that have nothing to do with wrongdoing. The reason to run all of them is that they are read together.
Details that are individually plausible can still form an inconsistent overall picture: a long-established trading history alongside a domain registered weeks ago, an operational address that does not fit the scale of business described, payment instructions in a name nobody can connect to the entity on the register. Nothing in that list is proof of anything. Taken together, it is a picture that does not hold, and that is the signal to slow down, ask direct questions and require evidence.
Verification is about reducing avoidable uncertainty before you commit. It does not guarantee an outcome, and it does not replace your own commercial judgement — but it means the questions you ask are informed rather than hopeful.
