Step 1
The phone number at sign-up
Whether the number belongs to the person, whether it is active and how long it has been in use. New numbers and numbers belonging to someone else go for an extra check.
Protecting classifieds and C2C sites from fraudsters
Burner numbers, other people's passports and repeat accounts from banned sellers are cut off at sign-up and before a high-value listing goes live. Checks over the API start at 5 ₽.

What the law says about classifieds sites
The law introduces no mandatory check on private sellers. But large platforms fall under the platform economy act, and the measures against fraud reach classifieds services too.
A user's identity is confirmed by the state services portal and the state identification system. NeuroVision checks the phone number, the document and the seller's details — the decision on access and badges stays with the platform.

This is where NeuroVision's checks come in.

Spotting fraudulent sign-ups: six tasks
Fraud at sign-up costs a platform the most: a single account means dozens of defrauded buyers and complaints. These are the tasks classifieds sites come to us with.
-
Burner numbers
Whether the number belongs to this person, whether it is still in service and how long it has been in use. A number bought yesterday is a signal before the first listing.

-
Someone else's passport for a badge
The document a seller uploads is read without manual entry and passes 40+ checks for forgery, traces of editing and photographs taken off a screen.

-
Repeat accounts
A banned seller comes back with a new number. A match of the passport or tax number against the platform's blacklist gives the repeat sign-up away.

High-value categories
Someone selling a car, a flat or equipment is run against the databases: passport validity, wanted lists, bankruptcy, bailiff debts and pledges over movable property.

Company and self-employed sellers
A company or sole trader is checked by tax number: status, nominee director, account freezes. A self-employed seller — their professional income tax status.

Sanctions and watchlists
Sellers and companies are run against the Rosfinmonitoring watchlist and sanctions lists, if the platform handles payment and delivery itself.

A private person, a self-employed seller, a company — three levels of checking
-
A private seller
The phone number and its age at sign-up. The document is checked for forgery when the seller asks for a trust badge. In high-value categories — passport, wanted lists, bankruptcy and pledges.
-
A self-employed person
Professional income tax status, passport validity and bailiff debts. The same set applies to independent tradespeople and service providers.
-
A company or sole trader
Status in the state registers, nominee director, account freezes and sanctions. Car dealerships, estate agencies and shops.
The dearer the category, the deeper the check.
You set the combination for each category yourself.
Checking a seller: from the phone number to the decision
The checks sit inside sign-up and inside publishing a listing. An honest seller never notices them; a fraudster stops at the first step.
Step 2
The document for a trust badge
The seller uploads a passport or a company document. The data is read without manual entry, the document is checked for forgery and the passport for validity.
Step 3
The decision and high-value categories
Every check returns a result, its source and the records found, in JSON. The platform's rules then grant the badge, limit publication or send the case to a moderator; before a listing for a car or a flat, the database checks run.
How fraudsters work on classifieds sites
A burner SIM card
The number was bought yesterday
An account is registered on a fresh number, «cheap» listings go up and the seller disappears. The age and activity of the number reveal this at sign-up.
A front seller
The number does not belong to the person on the form
The account is in one person's name and the number in another's. Checking the number against the name cuts off money mules and bought accounts.
Someone else's passport for a badge
A passport photo from a data leak
Someone else's or an edited passport is uploaded to get a trust badge. 40+ anti-fraud checks on the document, plus a passport validity check.
A car under a pledge
The seller says nothing about the loan
The seller's car or equipment is pledged against a loan — the buyer risks losing it. A check against the register of pledges using the seller's details.
A blocked seller returning
A new number, the same details
A seller banned for fraud signs up again. The passport or tax number matches the platform's blacklist.

Frequently asked questions about protecting classifieds sites
Private sellers — no. The platform economy act requires platform operators listed in the Ministry of Economic Development's register to check their partners — companies, sole traders and self-employed people — when the contract is signed. A private person selling their own belongings is not a partner.
Check the phone number — whether it belongs to the person and how long it has been in use — and keep out those you have already banned. The document submitted for a trust badge should be checked for forgery. These checks run at sign-up and do not get in the way of honest sellers.
Three checks against telecoms operators' data: whether the number belongs to the person on the form, whether it is currently in service, and how long it has been in use — from «under three months» to «over five years». Each costs 5 ₽.
No. Identity is confirmed by the state services portal and the state identification system. NeuroVision checks what the portal does not show: whether the number is new, whether the uploaded document has been forged, whether a banned seller is coming back, and whether the seller's car is under a pledge.
From the seller's details — passport validity, wanted lists, bankruptcy, bailiff debts and pledges over movable property: whether their property is pledged against a loan. NeuroVision does not check the car itself by VIN.
Yes. A company or sole trader is checked by tax number: status, nominee director, account freezes and sanctions. A self-employed seller — their professional income tax status, at 5 ₽ per check.
No. NeuroVision does not analyse messages, links or payment pages — that is the platform's moderation job. We close the fraudster's way in: the number, the document, the repeat sign-up.
In the NeuroVision cloud in Russia, or in your own infrastructure with an on-premises installation. 152‑FZ and 242‑FZ.
Checks by number and against registers cost from 5 ₽, and a package of 16 checks from the passport costs 50 ₽. Document anti-fraud and recognition are quoted individually. Test access lasts 1 month.
