To determine what type of passport you have, you need to know the common types of passports issued worldwide:

1. Ordinary Passport: Issued to regular citizens for international travel.
2. Official or Service Passport: Issued to government employees or officials traveling on official business.
3. Diplomatic Passport: Issued to diplomats and high-ranking government officials, often entitling holders to certain immunities.
4. Emergency Passport or Travel Document: Temporary passport issued in urgent situations like lost or stolen passports abroad.

Your passport will typically indicate its type on the identity information page or the passport cover. If you provide the country of issuance or more details about your passport, the type could be identified more precisely. Generally, ordinary passports are most common for general travel purposes.
