Pros and cons of having your doctoral degree on our ID In Germany and Austria¹, it is possible to have your doctoral degree noted on your passport, official ID (Personalausweis) and similar documents of identification.
Whether allowing this is a good thing in general is debatable but the subject of another question (that is arguably too opinion-based for this site).

Having acquired such a degree, I fail to see any strong arguments for or against making use of this as an individual (and the Internet does not provide much searchable information on this issue either). Obviously, it flatters the ego and can be used to impress some people, but then it involves some effort and may come off as arrogant to others. But I am wondering whether there are some situations where there is a more clear advantage or disadvantage or whether I am grossly misestimating the situation.

Note that I do not ask you to make this decision for me. I am fully aware that I have to weigh the advantages and disadvantages myself. I am just asking for arguments.

Finally, for the search engines: Was sind die Vor- und Nachteile davon, seinen Doktorgrad im Personalausweis vermerken zu lasen?
I did add the degree to the passport, and I can tell you that so far it only had disadvantages (though no severe ones).


I added my master degree, and did not need a new passport since. So now that I have my PhD, its not even accurate anymore.
In China, authorities looked at my passport and me very sceptically, when I did not add my degree to the train ticket, and thus the name differed between passport and ticket. They did not understand my explanation, but let me pass on the train anyway ;)
Most time I book a flight ticket, I can only select Mr/Mrs as title. So I have to think everytime, whether I should add the degree in the name field. Usually I don't do it, hence again the ticket and the passport show different names. It caused a strange look in America, but no serious problems.
My new colleagues (in a foreighn country) looked at me like i was crazy, when they saw it.
