You mean @fooco.com? Or @foocousa.com? Or @fooco.xyz? @fooco.ai? @foocoltd.net? @foo.co.uk?

How would LinkedIn validate that your email domain belongs to the company you claim to work for?

[HelloNurse]

With a company-managed list of owned domains where real employees have their work email addresses (unrelated to website domains).

And using DNS to prove that a domain is actually owned by this organization

[HelloNurse]

Email domains of employee addresses aren't necessarily owned by the company. For example:

  - a startup with legacy personal email addresses from one or two universities
  - a spin-off sharing the email domain (and the whole IT infrastructure) of the parent company
  - cheapskates using six approved free email services

For security purposes, on the other hand, the important part is proving that the LinkedIn account is owned by the organization.

Then there are old school ISPs where there was no separation between company and customer email addresses.

[jaapz]

So? Then you can't do this. For companies that do want more control over their linkedin organizations, it is still a useful feature. For companies using free e-mail services... they probably don't care anyway.

[DaSHacka]

Presumably because the official company page is registered under it?

[account42]

Not all companies use email addresses under the same domain as the "official company page" though.

What HelloNurse said, whoever it is that runs the company page on LinkedIn provides a list of domains that they consider theirs.
