Passport Online Services refer to digital platforms provided by governments or authorized agencies to facilitate various passport-related processes. These services typically include:

1. Application Submission: Users can fill out and submit passport applications online. This often includes providing personal information, uploading necessary documents, and paying fees electronically.

2. Tracking: Applicants can track the status of their passport applications in real time, checking where their application is in the processing queue and receiving updates.

3. Renewal and Replacement: Online systems allow for the renewal of expired passports or the replacement of lost or stolen ones. This process is usually streamlined to minimize the need for in-person visits.

4. Appointment Scheduling: For tasks that require in-person visits, such as biometric data collection, online services often include tools for scheduling appointments at passport offices.

5. Information and Guidance: These platforms provide detailed information on the required documents, eligibility criteria, and step-by-step guides to assist applicants through the process.
