What is the format of Hungarian telephone numbers? How many digits are in the area code? How many in the telephone number?

Is there a web site where you can do a reverse search of a Hungarian telephone number?

I have a strange caller ID of a number beginning with 367. (This is not an area code in the United States). I understand that 36 is the country code for Hungary. Following the 36 are eight digits beginning with 7.

Any insights or suggestions will be appreciated.

Before you ask, yes, it is possible for someone in Hungary to know me.
