Do We Need Passport for Domestic Flights in India (2025): The Definitive Answer
- Do we need a passport for domestic flights in India? Indian citizens cannot use passports for flights within the country. Because of this, domestic air travel is easy for Indian citizens, as there is no need for a passport.
- Many people mix up passport rules because they typically associate air travel with travel abroad. Many people who fly for the first time think they need a passport for all flights, but India’s aviation rules say domestic travellers have different and simpler requirements.
- When boarding a domestic flight, passengers are asked to prove they are Indian citizens and their identity, instead of requiring travel authorisation. Because domestic flights are within India, you don’t have to worry about the extra documents required for international travel.
- At domestic terminals, airport security will accept Indian IDs recognised by the government in place of traditional passports. This method delivers security and helps reduce difficulties in domestic air travel.
- The policy foundation for this area accepts that domestic air travel is vital for the growth of economies, family unions and mobility among regions. Asking people to use passports just to travel within their own nation would unnecessarily restrict citizens.
Travel Type | Passport Required | Alternative IDs Accepted | Additional Documents |
Domestic (Indian Citizens) | No | Multiple government IDs | Boarding pass only |
Domestic (Foreign Nationals) | Yes | No alternatives | Valid visa required |
International (All Travellers) | Yes | No alternatives | Visa, tickets, etc. |
Why Domestic Travel Doesn’t Always Need a Passport (2025)?
- The main reason passports are not required on domestic flights is related to what a passport is meant for. A passport is recognised everywhere as evidence of a person’s citizenship and lets someone cross international borders. Since all domestic flights take place within India, services for international flights are not necessary.
- Identity verification is most important for travel within India, instead of authorisation to enter or leave the country. The government believes that several types of identification provide enough information to prevent fraud.
- The policy also focuses on making economic accessibility a key part of its strategy. Applying for a passport means paying fees, waiting for it to be processed and submitting documents, which may stop citizens from travelling inside their country for important reasons. Today’s alternatives allow every economic sector to board domestic flights easily.
- This strategy depends on having good administrative efficiency. Airports are able to process more people faster when they accept several types of identification, instead of having to use just one document. Having flexible staff at airports allows work to move smoothly, and manageability improves.
- The site’s safety is assured by using a verification system that takes many government-issued IDs into account. All valid forms of ID have specific security measures and ways to verify a person’s identity without slowing down airport operations.
Acceptable Documents for Travel Within India in 2025
Virtually every Indian citizen can travel by air domestically, thanks to the diverse list of documents the ministry accepts. By using this method, the government is letting everyone from various walks of life participate in air travel.
They cover photo IDs issued by the central government, the governments of states, public sector undertakings or recognised schools and universities. Accepting a wide range of criteria means that almost everyone is able to get identification that suits them.
Having a professional identification card given by a government institution makes travelling within the country easier. Such cards are also available from the central and state governments, public sector companies and recognised institutions of education.
Checking identification documentation, such as attested photos on nationalised bank passbooks, is a new way to securely prove someone’s identity. This way maximises the chances for rural areas, where most people do not have access to other types of official photo identification.
In addition, pension cards that have photographs are issued to senior citizens, and state governments provide disability ID cards. The rules give people with specific needs access to domestic air travel.
ID Category | Examples | Target Population | Special Benefits |
Universal IDs | Aadhaar, Passport, Voter ID | All citizens | Widely accepted |
Financial IDs | PAN Card, Bank Passbook | Working professionals | Quick verification |
Professional IDs | Government employee cards | Public sector workers | Institutional backing |
Specialized IDs | Pension cards, Disability cards | Vulnerable populations | Inclusive access |

Essential Steps to Support Children and Minors in 2025
To identify minors and children by air, there are set rules about their documents that keep security high but allow families with children to travel comfortably.
Children under two years old must present a birth certificate or hospital discharge paper to get their age checked and pay for their tickets. You are identified, and your age is confirmed with these documents for airline ticket prices and safety rules.
Anyone between the ages of 2 and 12 is required to have identification from the government, which may be a school ID card, Aadhaar or birth certificate. Since young children usually do not have all the basic adult documents, the rules allow some flexible types of identification.
Minor travellers are required to submit parental or guardian consent, verified copies of the guardian’s ID and detailed information for the receiving persons at their destination airport.
When children are travelling with people other than their parents, family travel papers should confirm the relationships among them. Records of birth certificates, adoption or court-appointed guardianship are required.
For school trips, simplified paperwork is used by institutions to cover the group, including multiple students who are supervised by teachers while in transit.
Age Group | Required Documents | Additional Requirements | Guardian Involvement |
Infants (0-2 years) | Birth certificate | Age verification | Parent/guardian required |
Children (2-12 years) | School ID or Aadhaar | Guardian consent if alone | Recommended accompaniment |
Unaccompanied Minors (5-12) | ID + Consent forms | Receiving party details | Mandatory procedures |
Teenagers (13-17 years) | Government-issued ID | Parental awareness | Situation-dependent |
What to Do if You Lose Your ID at the Airport? Expert Tips for Smooth Travel in 2025
- There are rules in place at airports for what to do with passengers who arrive without the correct documents. They ensure both safety for others and support for those without transportation.
- If someone loses their identification, the police report is the first step to take. Normally, airport staff require you to show proof of the loss before using other forms of verification.
- It is possible to ask passengers to present an affidavit with their sworn statement of identity, and you can accept secondary documentation, for example, credit cards, employee IDs or digital substitutes for lost documents, too.
- Depending on the airline, guidelines on lost ID may be more understanding than with some other carriers. Passengers are advised to reach out to their airline as soon as their identification is lost, to learn what can be done.
- Using family members or employers to check travel documents may help confirm someone’s identity. Some airports will allow verification by phone or documents from a trusted third party to identify passengers.
- Since lost IDs mean extra processing time, timing is crucial in such cases. Allow yourself plenty of time at check-in when you are concerned about your identification documents.
Digital ID Solutions and the use of DigiLocker
- Now, thanks to digital platforms, governments no longer require physically carrying photo IDs. Passengers at Indian airports now show their identification differently, thanks to DigiLocker.
- Via DigiLocker, airport systems now easily verify the digital documents uploaded to the government’s cloud. Integrating these two features is a major step toward having paperless trips.
- Digital platforms offer a range of security features to make sure the travel documents are real and easy for passengers to access. Blockchain technology and encryption are employed by the system to make documents safe and reliable.
- Presenting a digital ID with apps is now common at airports across India. With these apps, passengers can keep and present different documents for identification on digital devices.
- Airport security now allows you to use digital files while still ensuring documents are checked accordingly. Security officers are taught how to verify and authenticate electronic documents.
The introduction of digital ID techniques is part of India’s Digital India efforts to ensure paperless administration and make it easier for citizens.
Digital Platform | Supported Documents | Airport Acceptance | Security Features |
DigiLocker | Aadhaar, PAN, DL | Universal | Government encryption |
Digi Yatra | Boarding pass + ID | 20+ airports | Facial recognition |
m-Aadhaar | Aadhaar card only | Most airports | UIDAI security |
Airline Apps | Boarding passes | Carrier-specific | Basic encryption |
Digi Yatra is the best digital travel solution today, using facial scanning and digital documents. Travelling from start to finish can now be done without ever having to touch anything.
When digital ID systems use facial recognition, passengers can breeze through airport checkpoints. After being registered, a passenger is let through airport security and boarding, solely based on facial verification connected to their digital identification.
Working with blockchain technology, digital ID platforms secure documents and keep them from being altered. Using this method, you get more protection along with easier digital access than you would with simple paper documents.
Users of digital IDs can manage their personal information, and the data is removed automatically after they finish the flight. Technological convenience is made possible by this approach while giving much attention to privacy concerns.
Travel Documentation and Regulations for Domestic and Sensitive Regions in India
- Regulations for Indian aviation are similar throughout the country, but since each region is unique, some differences appear in domestic travel documentation. Learning about these details allows tourists to prepare for different places.
- To visit some regions at the borders or sensitive places, travellers may be required to show additional permits with their identification. Usually, these regulations are designed for particular districts instead of all the states.
- While individual states set their own policies on COVID protocols, most requirements have been made simpler since 2025. Health screening processes in some places may need you to provide more documentation than usual.

- People travelling from another country to the Andaman and Nicobar Islands must bring their passports and valid papers, regardless of whether their flights are international or domestic.

Border Areas | Special permits possible | Select districts | Standard ID is usually sufficient |
Tribal Areas | Entry permits | Northeast regions | Varies by specific location |

Metropolitan Areas | Standard procedures | Major cities | No additional requirements |
Things to Avoid and Useful Tips for Stress-free Domestic Travel in India 2025
- Your domestic flight booking can be successful only if you avoid typical errors in documentation that delay you or prevent you from boarding the aeroplane. If you know about these problems, you can handle your airport experience with less difficulty.
- The most common problem with documentation happens when a passenger’s name on the ticket is not the same as the name on the ID. Making sure the dog’s name on the file is the same as on the boarding ticket is very important.
- Anyone flying with expired identification ends up having problems. Being just a day late with your ID card can lead to boarding rejection or extended delays.
- It allows people travelling to access identification, no matter if their physical cards are gone. Holding your digital files in more than one secure place gives you options in case of an emergency.
- When travelling at major travel times or with alternative identity papers, allow extra time for document checking at the airport.
- Checking an airline’s rules ahead of your trip helps you learn about any special policies of the carrier that are not part of standard regulations.
Problems With Name Mismatches And Their Solutions in 2025
- The rules for identification mean tickets and passports should match exactly, but airlines have created ways to handle small differences that look innocent.
- The way you spell your name when booking should match the format used on your identification. Avoid choosing nicknames, cutting down your name or changing the spelling when booking your ticket.
- Making sure the titles on tickets and IDs are the same avoids most verification issues. Titles on the booking document should be the same as those on the passenger’s identity documents.
- If your name is slightly different, there are procedures to correct this, although it may cost you a little more or require some additional documentation. If your name doesn’t match on your ID, contact your airline as soon as you become aware.
- A name change on legal documents must take place before you can travel abroad. Any recent changes in marital status or legal name should be noted in the identification you use to travel by air.
Mismatch Type | Severity Level | Typical Resolution | Prevention Strategy |
Minor spelling differences | Low | Airline discretion | Double-check booking details |
Title variations | Low | Usually accepted | Use consistent titles |
Significant name differences | High | Rebooking required | Verify ID before booking |
Legal name changes | High | Updated documents needed | Update IDs promptly |
Experts Tips for Managing Expired Travel Documents and Identification in 2025

Some airlines offer grace periods which allow additional time for travellers who supply extra documents.
Allow for extra time for processing when scheduling renewal near a trip. People who travel should ensure their identification is up to date long before it expires, most importantly, before they travel.

You can use emergency renewal procedures for immediate travel needs, which often require additional costs and fast processing.
