Is it possible and necessary to place several identical micro-markups on a page?

Question

Search Engine Optimization

Implemented "Organization" schema.org micro-markup in the footer of the site, the footer is common for the entire site.
When I got to the contact page, I thought, is it necessary to implement it there?!
Taking into account the fact that the data in the footer and on the contacts page are almost the same, to be more precise, on the "Contacts" page there is more data (additional phones, emails).

Answer 1

Here, rather, the question is, was it necessary to introduce markup in the basement? I think not. But on the contact page you definitely need it.
