Isn't it under Address? Go to Field Managemnet and check the list of fields and which objects they are on. Maybe it's not being synced yet.
The following Marketo Standard fields are mapped with SFDC Contact Mailing fields :
- Address (Mailing Street)
- Postal Code (Mailing Postal Code)
- City (Mailing City)
- State (Mailing State)
- Country (Mailing Country)
What do you mean not in Marketo? Check they have not been hidden in the admin -> field management.
Also, in order to get quicker answers, it's better to ask your questions as new questions than continue to comment on old ones.
