Hello Hervé TUC,

In the rare case that two companies have the same address. You can copy the address info to a new node.

This however generally does not happen, ether the new company takes over the old address or one of the two is not a company that is mappable. For example, holding companies or other companies that have no poi value.

Names of anything but especially companies should not be directly copied into OSM. The name needs to be curated for example no abbreviations no special characters. And no company type indicator like GMBH, LLC, BV etc.

For example, if a company has a name like “A” then the “ is removed. 

Greetings,

Tjuro
