Cert d'addition is and was the name in the French patent systems for supplementary patents, also called patents of addition.

They seem to have changed their numbering procedures over time. In an earlier period, cert d'additions don't seem to have their own numbers. Then at some point they start to have their own numbers, but starting from a small number. By 1915 it's easy to tell whether a patent number is an original or a cert d'addition by whether it has a number less than 30,000 or greater than 300,000; there weren't any in between.

If we study here we can find when the procedure change occurred, if it's as simple as just described, a switch from one to another.

Example: Our evidence doesn't show Patent FR-1894-205155.2 having its own unique official patent number, so we show it with a suffix ".2". It may be that this addition did have a number, and we will find it someday. Or maybe they didn't assign cert d'additions their own numbers at this stage. Later, they did. We can document the cert d'addition numbering procedures as we work them out.
