Is it possible to unambiguously determine that the user is the owner of the organization?

Question

API

Is there a way to understand that a user who registers in a certain service is definitely the owner of the organization?
There are some services that provide their own API for searching legal entities, but the catch is that absolutely anyone can go to the website of the Federal Tax Service, find any organization, get all its data and introduce themselves for it.
If there was some way to get the contact details of an individual entrepreneur or legal entity and send something like an access code to email or phone, as is usually the case, but as I understand it, there is no way to get contact details.
We are talking about automating this process in order to avoid bureaucracy and manual verification of documents, etc.

Answer 1

Automatically and with a 100% guarantee - no way.
You can request a qualified EDS (essentially a certificate issued by some state center) - but there is no law obliging me to have it.
You can request a letter from the address @nichego.net (if you are registering on behalf of the office "OOO Nothing No") - but anyone can write from this domain, and not at all a co-owner :)

Answer 2

electronic signatures are certainly not 100%, but better than nothing

Answer 3

A standard check is an extract from the Unified State Register of Legal Entities / Unified State Register of Legal Entities no older than 3 months + a copy of the certificate of registration of the legal entity.
If the organization has a website, let them register from the mail in their official domain.
UPD : Yandex.Directory uses confirmation of ownership of an organization by phone . They require that the official phone number be on the company's website or in its group on social networks.
The code is sent to the phone by voice (you can send it to mobile phones via SMS).
The question of whether the director authorized a specific person is already internal disassembly within the company and compliance with job descriptions.
When registering on the service, require that you indicate your full name, PSRN / PSRNIP and the website page (group in social networks) where the phone numbers of the company are indicated. OGRN / OGRNIP make their way online on the tax website (that the company has not been liquidated).
And in the offer agreement, set out the procedure for resolving conflicts in cases of registration under the name of a foreign company.

Answer 4

the fact that he is the "owner" - you can not check in any way. you can check the eligibility of the director.
Today in the Russian Federation it is impossible to do business without an ES (if you are a little more than a micro-organization), neither VAT nor personal income tax (if 5 (or 10) people) is filed.
Therefore, if the service is serious, then demand either an ES or payment of a registration fee - 100 rubles.

Answer 5

Is it possible to unambiguously determine that the user is the owner of the organization?

- it can be determined with 100% certainty only through personal contact and acquaintance with the documents (charter, extract, etc.) Today, even 100% ES does not give any guarantee.
The owner of a particular organization (de jure) is confirmed by an extract, protocol / decision, charter (if this is not a template) and if there are several participants, then the memorandum of association is added to the list if we are talking about an LLC (which is more common), in other cases other documents .
