GST number se supplier ka mobile number is something buyers search for at a very particular moment: a new supplier has sent a quotation, the price looks attractive, and now they are asking for an advance. The registration number on the quotation makes the offer look official, and the temptation is to treat it as proof. It is not proof. It is a claim that you can test, and a mobile number is only one part of that test. This article walks through how a careful buyer verifies a supplier before the money moves.
Why advances attract fraudsters
An advance payment is the point where a stranger’s promise turns into your cash leaving the account. People who run fake supplier schemes know this, so they dress up their offer with everything that looks legitimate: a registration number, a company-style email, a letterhead, even photographs of a godown. The only thing they cannot easily fake is a long history of real dealings that you can independently confirm.
The scheme often works because buyers verify one thing and stop. They see a registration number, feel reassured, and send the money. A fraudster only needs to copy a real firm’s registration details onto a fake quotation to pass that single check. So the question is not whether a number exists, but whether the person you are talking to is truly connected to it.
What the registration check can honestly tell you
Searching a registration number in the public view shows identity and status details such as the legal name, the type of business, the state, and whether the registration is active, suspended or cancelled. That is useful, because a cancelled registration or a name that differs wildly from your quotation is an immediate warning.
What the check does not do is prove that the person messaging you owns the firm, and it does not supply a trustworthy mobile number for them. Treat the result as a way to confirm that a real registered business exists under that number, and then ask a second question: is the human on the other end authorised to speak for that business? Everything after this point is about answering that second question.
Reading the quotation against the registration
Lay the quotation next to what you found. Does the firm name match, including spelling? Does the address on the letterhead fit the state indicated by the registration? Is the trade you are being offered consistent with what a business of that kind would sell? A dealer registered as a small stationery trader offering heavy machinery at a discount deserves hard questions.
Also look at the bank details they ask you to pay into. The account holder name should match the registered firm or its proprietor. A request to pay into an unrelated personal account, or into an account in a different name, is one of the most common signs of a payment-diversion trick. You do not need to be rude about it. Simply say your accounts policy requires the payee name to match the invoice, and see how they respond.

Getting a contact number the right way
You may have been given a mobile number in the first message, and that is a start. For anything beyond a small order, however, try to find a second route into the firm that does not depend on the person who contacted you. Look for the number that appears in the firm’s own published channels, such as a website they control or listings that other buyers have used, and compare it with what you were given.
If the numbers differ, ask why. A genuine business usually has a plain answer, such as one number for sales and another for accounts. A fraudster tends to become vague or pushy. Never use a number sourced from leaked lists or shady sellers, because it both breaks privacy norms and gives you nothing you can trust; the point is to reach the real business, not any person who happens to have a phone.
The callback as a verification step
Once you have two independent routes, use one to check the other. Phone the number you found yourself and ask whether this person works there and whether the quotation is genuine. Ask for the person by name and designation. Then call the number you were originally given and see whether the story is consistent.
This simple callback defeats a surprising number of scams, since the fraudster controls the number in the message but not the number you found separately. If the genuine business says it has never heard of the quotation, you have saved yourself an advance. If they confirm it, you have a name and a confirmed contact in your records, which is valuable whatever happens next.
Asking for documents that are hard to forge casually
Request supporting documents that a real operating supplier would handle every day: a previous invoice they are happy to share with the customer’s details hidden, a delivery challan format, a transport arrangement, and proof of the premises. Ask for a short video call if the order is large, where they show the stock or the workshop.
None of this is insulting. Established suppliers expect verification and often respect buyers who do it. It is the supplier who resists every reasonable request while insisting on speed who should worry you. Combine the answers with what you found in the registration, and you will have a layered view in which no single detail has to carry the full weight of your trust.
Structuring payment to limit your risk
Even after verification, shape the deal so that a mistake is survivable. For a first order, propose a small trial purchase instead of a large advance. Offer to pay part on dispatch and the balance on delivery, or use a method where payment is released when goods arrive. Pay through traceable banking channels and keep the receipts.
If the supplier insists on the whole amount in advance for a first deal with no history, treat that as information about them. Honest firms understand why a new buyer wants to start small, and many will offer references to other customers. Calling one of those references, with permission, is a stronger check than any number of messages.
Handling the privacy of the person you reach
Remember that the mobile number of a small supplier is often their private phone. Use it for the verification and the order, and do not circulate it or add it to marketing lists. If a supplier says they prefer messages on a certain number or at certain hours, follow that preference.
This is more than manners. Buyers and suppliers in the same trade circle talk to each other, and a reputation for handling contact details responsibly makes suppliers more open the next time you need a quick answer or a better rate. It also keeps you on the right side of reasonable expectations about personal data.
What to do if something feels wrong
If the callback fails, the account name does not match, or the registration status is not active, stop and do not pay. Keep every message, the quotation, and the account details they gave you. Tell your accountant and, if money has already been sent, contact your bank quickly through its official channels to ask what can be done.
You can also report suspicious activity through the channels that the authorities and your bank provide, and warn colleagues in your trade group without making accusations you cannot support. Stick to describing what happened and what you observed. The goal is to protect the next buyer while staying factual about what you actually know.

Keeping a verified supplier record
After a successful verification, save the findings in one place: the legal name, the status you saw and the date you checked, the confirmed contact numbers and who they belong to, the payee account name, and the people you spoke to. Revisit it before large later orders, because status and contact details can change.
A tidy supplier record turns a one-time worry into a habit. Next time a quotation arrives with a registration number and a request for an advance, you will already know which checks to run, in which order, and what a normal answer sounds like. That habit is worth far more than any number you could find in a hurry.
Red flags that deserve a pause
Some warning signs show up again and again in supplier scams. Extreme urgency is one: the offer is only valid today, the stock is almost gone, the advance must be sent before the evening. Another is a price far below what the market normally asks for the same material. A third is reluctance to meet, to speak on a call, or to let you visit the premises, even when the order is large.
None of these proves wrongdoing on its own. A real supplier can be busy and a real bargain can exist. But when two or three of these signs appear together, slow down. Fraud depends on speed, because the longer you think, the more likely you are to ask the questions that break the story. Allow yourself a full day, talk to your accountant, and let the supplier prove their case.
Involving your accountant and your bank
Your accountant sees dozens of suppliers and has a feel for what looks ordinary. Share the quotation, the registration details you found, and the payment request, and ask for a quick opinion before the money goes out. A five-minute chat costs very little compared with a lost advance.
Your bank can also help. Before a large transfer to a new payee, ask whether the bank offers a way to confirm the account holder name, and use it. If the name that comes back does not match the firm you believe you are dealing with, that mismatch is exactly the kind of fact you were looking for. It is far better to learn it before sending money than after.
Building a standard checklist for new suppliers
Turn all of this into a one-page routine that anyone in your business can follow. It should say which documents to ask for, which checks to run on the registration, how to obtain and confirm a contact number independently, who must approve an advance, and what to record afterwards.
A routine takes emotion out of the decision. When a persuasive supplier is on the phone and a deadline is looming, people skip steps. A written checklist, signed off by a second person, makes skipping harder. Over time you will also notice which questions genuine suppliers answer easily, and that gives you a quicker sense of whom to trust.
