Step 1
Consent in the form
In the registration or application form the customer ticks a separate box agreeing to receive information about them as a subscriber. The consent text is a separate document, not a line in the offer.
Matching a full name to a phone number and email
The customer gave a name and left a number — check that the number really belongs to them, is in service and has been in use for more than a week. Telecom operator data with the subscriber’s consent, a “yes” or “no” answer. Link the email and the number to a passport: send a document check link to them.
We check against data from:
Phone Full name Email Russian passport
Data is stored in Russia · Register of Russian software No. 19972 · Federal Law No. 152‑FZ
Number, email, document: a catalogue of customer contact checks
Checks run on their own or together with other database checks in one request. The card shows the source, what comes back in the response and which data is needed. The full catalogue is on the database checks page.
Customer’s phone number
The person is already known and their contact is being checked. Only mobile numbers of Russian operators, only with the subscriber’s consent.
- Telecom operators
The number belongs to the person
Confirms the link between a number and a full name: whether the number is registered to the person who gave their name in the form. A “yes” or “no” answer.
Required: phone and full name.on request

The number's activity
Whether the operator currently serves the number. A disconnected number in the form is a reason not to send a code or money to it.
Required: phone.on request

The number's age
How long the subscriber has used the number: from “less than three months” to “more than five years”. A number bought last week is a signal to look closer.

Number and passport in one record
When a “the number is theirs” answer is not enough.

Confirming the link between a full name and a phone: what to send and what the operator returns
The input is only what the customer has already entered in the form. The output is a short answer that is easy to put into a rule: let through, ask for a document or pass to an employee.
Field format phone and errors — in the check launch documentation
- Enable matching
Number and full name
Whether a private individual with this full name uses the number.
You send:
- a Russian mobile number — 10 digits, or 11 starting with 7 or 8
- surname, first name and patronymic from the form
- a flag of the subscriber’s consent in your system
You get:
- “yes” or “no”
- check outcome: completed, skipped, source unavailable
- response time
- Add to the flow
The number itself
Whether the number is live and whether the subscriber has had it for long.
You send:
- the phone number only
You get:
- whether the number is in service now
- how long the subscriber has used the number: from “less than three months” to “more than five years”
- Discuss email
Email and full name
Whether the address matches the customer.
Matching on request:
- address and full name
- sources and response format — at onboarding
A reliable link:
- a passport and liveness check link is sent to this address
- the session result — together with the address the customer came through
Consent, request, response: how a customer’s phone number check works
Four steps that fit into registration or an application without an extra screen for the customer.
Step 2
API request
Your server sends the number, full name and the list of required checks to kyc/checks/run and immediately gets a run number. The number can be sent together with a passport — database checks then run in one request.
Step 3
A response for each check
The result is fetched with a request kyc/checks/result every 5–10 seconds. Each check gets its own line: completed, skipped or source did not respond, and the answer itself.
Step 4
Decision rule
“Yes”, a live and long-held number — let the customer through. “No” or a fresh number — send a passport and liveness check link, or pass the application to an employee.
“Yes”, “no”, “not checked”: how to read the response for a number and an email
-
“Yes” — the number is theirs
The number is used by a person with this full name. This is a good signal but not an identity check: the number confirms a contact, while who is holding the phone is shown only by a document with a selfie.
-
“No” — a reason to ask, not a verdict
The number may be registered to a spouse, a parent or an employer. Do not reject automatically: ask for a passport via a link or pass the application to an employee.
-
“Not checked” — does not mean “clean”
If the number does not look like a Russian mobile number or the full name is incomplete, the check is skipped and the response says which data was missing. If the source did not respond — run it again. A skipped check is not charged.
-
A fresh number and email — together with everything else
A number younger than three months and an address that is a day old prove nothing on their own. Decide on the whole picture: the form, the document, database checks and behaviour at registration.
How to combine signals into one score — on the page registration anti-fraud.
Registration, loan, payout, number change: where to match a contact
A phone number is the key to an account, a confirmation code and money. Check it where a mistake costs the most.
-
Loan and instalment applications
The number in the application is theirs, long in use and in service. An application with someone else’s or a just-bought number is visible before any money is paid out.
Instalments and BNPL -
Marketplace seller
The seller account and payouts are tied to a number. Match the number to the full name and check the passport against the Ministry of Internal Affairs database — before the first payout.
Marketplaces -
Courier and contractor
The contractor works from their own number, not from a number “lent” to them together with the account.
-
Rental and car sharing
Before the first trip — the number belongs to the renter, not to someone registering dozens of accounts on fresh SIM cards.
Driver and vehicle -
18+ service
Legal age according to the operator — without a passport scan. If there is no answer — a document and liveness.
Age check -
Number change in the profile
The new number must belong to the account owner. If the answer is “no” — a document and selfie check again, not a code to the new number.
Access recovery
When to match a contact again: a new number, a withdrawal, a long pause
A number the customer had at registration may belong to someone else a year later. Re-matching — at the moments when it matters.
- A new number in the profile — match it to the account owner’s full name before the first code is sent to it
- A new email — a check link to the old confirmed channel, or a new document check
- The first withdrawal, a payout to a seller or contractor, a change of bank details — activity and owner of the number that will receive the confirmation
- A large amount above your threshold — plus a passport check against the Ministry of Internal Affairs database
- An account with no logins for longer than the period you set — the number may have gone to another subscriber. Check the owner before sending a code
- A refusal on the number after a pause — a repeat check “document + liveness again”, not access with the old code
- Your system runs matching over a customer list itself: each person is a separate API request
- Disconnected numbers in the database — a reason to update the contact before the customer needs to restore access
- Thresholds and periods are set by your company. Re-checking the whole customer base against lists and sanctions — on the page AML client monitoring.
Someone else’s SIM card, a fresh number, a disposable email: what gives a fraudster’s contact away
It is easier for a fraudster to buy a number than to forge a passport. So the first traces show up in contacts.
-
A number in someone else’s name
One person submits the application, while the number is registered to another. Matching to the full name answers “no” — and before any money is paid out the application goes to a document check.
-
A batch of fresh numbers
Dozens of accounts for bonuses or reviews are registered on numbers less than three months old. The number age separates them from long-standing customers.
-
A disconnected number in the form
The number in the form is not in service: the code will not arrive and the customer will not be able to confirm the transaction. The activity check catches this before the code is sent.
-
A one-day email
The address was created for the registration and no longer exists. A passport check link sent to such an email will simply not be completed — and that is an answer.
Subscriber consent, 126‑FZ and 152‑FZ: on what basis to match a number
Subscriber information
Restricted-access information
Everything a telecom operator knows about a subscriber from the contract is restricted-access information. Information about a subscriber who is an individual is passed to third parties only with their consent, except in cases expressly named in a federal law (Art. 53, Part 1 of 126‑FZ).
No consent — no run
A consent flag in the request
Number checks run only if your system has received the customer’s consent. Storing proof of consent is your company’s task: in a dispute it will be requested from you.
Consent — as a separate document
From 1 September 2025
Consent to personal data processing must be specific, informed and given separately from other documents the person signs (Art. 9, Part 1 of 152‑FZ). A tick box inside an offer does not qualify.
Basis and purpose
Your company decides
Besides consent, processing is possible for a contract with the person or to meet a legal obligation (Art. 6, Part 1 of 152‑FZ). For telecom operator data the subscriber’s consent is specifically required.
Only what is needed
Minimum data
To match a number, the number and the full name from the form are enough. A passport and an address are not sent in a number request.
152‑FZ
Only for legal entities and sole traders under a contract
Data in Russia
Finding a person by number is not possible: limits of contact matching
-
Owner by number
Matching answers the question “is this number theirs?” when the person has already given their name. It is not possible to find out a full name by number without a form.
-
Operator and region of the number
The service does not report which operator serves the number and where it was issued. This is not needed for a “yes / no” answer.
-
Numbers from other countries
The checks work with mobile numbers of Russian operators. A foreign customer goes through a document and liveness check.
-
Calls, messages, geolocation
Call records, messages and the subscriber’s location are not part of the response and cannot be.
-
Number limit and Gosuslugi
How many numbers a person has, and whether subscriber information is confirmed through Gosuslugi, is known to the telecom operator and the state system. More — on the page for telecom and online services.
-
Identity by number
A number does not replace a document. Who is in front of you is confirmed by a passport with a selfie and liveness — passport and selfie check.
The service works only with legal entities and sole traders under a contract — for customer registration, loans, payouts and hiring. It is not possible to check someone else’s number for yourself through NeuroVision.
Price of matching a full name to a phone and email
You pay for completed checks, with no subscription fee. A check skipped for lack of data is not charged.

Frequently asked questions about matching a full name to a phone and email
Your system sends the number and full name from the form to the API and selects the checks: number owner, activity, number age, legal age. The response comes separately for each check, from telecom operator data and only with the subscriber’s consent.
No. Matching confirms that a number belongs to a person who has already given their name. The service does not let you find out the owner, operator or region by number. We work only with companies and sole traders under a contract.
“Yes” or “no” and the check outcome: completed, skipped for lack of data, or source did not respond. The activity and number age checks return the number status and a range from “less than three months” to “more than five years”.
Yes. Subscriber information is restricted-access information and is passed to third parties with the subscriber’s consent (Art. 53, Part 1 of 126‑FZ). Consent to personal data processing is given as a separate document (Art. 9, Part 1 of 152‑FZ). Without consent, number checks do not run.
Mobile numbers of Russian operators: 10 digits, or 11 starting with 7 or 8. Spaces, brackets and “+” are stripped automatically. For a foreign number, use a document and liveness check.
Two ways. Matching a full name to an address is enabled on request — we agree the sources and response format to fit your flow, including via the API. More reliable — send the address a one-time passport and liveness check link: whoever completes it is tied to both the address and the document.
Not necessarily. The number may be registered to a relative or an employer. Ask for a passport via a link or pass the application to an employee instead of rejecting automatically.
No. Mobile ID is a general name for services in which an operator confirms a subscriber’s login or transaction through the SIM card. NeuroVision matches a number to a full name using operator data and links the number to a passport through a document check.
Yes. A single kyc/checks/run request carries the number, full name and passport — number checks run together with database checks: passport validity, tax number, lists, sanctions, wanted lists.
Number checks and email matching are on request, a manager calculates the price for your volume. A document check link with liveness — from 29 ₽ per session, without liveness — from 16 ₽, a package of 16 passport checks — 50 ₽.
