You do not need a passport to travel between countries that are apart of the European Union. Since Hungary joined the EU in 2004, you can travel freely between Germany and Hungary. I would wary of traveling to a foreign country without a passport though, because even if you in the Army, you will be required to provide papers if arrested. It could be more trouble than it is worth. So technically, yes, you can travel freely without having to show any documentation, but it isn't necessarily a good idea.
If you have parents that emigrated from Hungary, acquiring Hungarian citizenship and obtaining a Hungarian passport is relatively easy and inexpensive (around $300 Cdn at this time), assuming you have proof of your ancestry and other relevant Canadian documents that are required for the application.
Yes. Virtually any passport has a passport number
You Don't. You need to have a passport in order to have a passport number.
The passport card itself is the passport. However, it has its limitations in use as compared to the traditional book passport.
As long as you are an EU citizen, you will not need a passport to travel to any EU country. As a Hungary resident, you can travel with only your ID to Greece from UK.
There is a "Passport Card No." on the top right on the front of the passport card. But it has nothing to do with your passport booklet. You should notify the police as soon as possible.
No you can't. Passport number is only written in your passport booklet.
