Normally, we classify documents into 4 main types: passport, ID card, driving license, and residence permit. Please follow the link to see a list of documents for each country.
There are some types of documents we work with, but they may be difficult to classify (e.g. the Australian seafarer's service book or Aadhaar in India). You can upload such docs to our service if they prove your identity in your country, and then we will add them, according to your needs.
