Before an international trip, you may come across terms such as eVisa, eTA, ESTA and visa. They can all involve an online application, but their legal purpose and travel conditions can be very different.
The entry permission you need depends on your nationality, passport, destination, planned length of stay and purpose of travel. Always check the requirements that apply to your individual journey before you leave.
Key takeaways
- An eVisa is a visa issued electronically, while an eTA and ESTA usually apply to visa-exempt short stays.
- For visa-free travel to the United States of up to 90 days, eligible travellers under the Visa Waiver Program generally need a valid ESTA.
- Electronic authorizations are usually linked to the passport used for the application and may become invalid when you get a new passport.
- ETIAS is expected to launch in the final quarter of 2026 and is not yet operational.
- No authorization guarantees entry, as the final decision is made by border officials.
Do you need a visa or are you visa-exempt?
Travellers who are required to hold a visa generally need one before travelling, and some destinations issue these visas as eVisas. Visa-exempt travellers may still need an electronic pre-travel authorization, such as an eTA or ESTA.
Your destination determines which category applies based on your nationality, passport and planned stay. Your travel purpose, length of stay, previous travel history and any grounds for ineligibility may also matter.
Visa-free travel does not necessarily mean authorization-free travel. A country may exempt certain nationalities from visa requirements for short tourist stays but still require a digital security check before departure.
The key order is this: first check whether you need a visa, then identify the right visa type or travel authorization. The All countries overview provides entry information for each destination.
How does an eVisa differ from a traditional visa?
A traditional visa and an eVisa share the same basic purpose: both are government permissions for a specific type of travel or stay. With an eVisa, the application, approval or proof of approval is handled partly or entirely online.
The traditional visa
A visa is usually requested before travel. Depending on the country, the responsible authority may be an embassy, consulate, visa application centre or government online portal. The visa category you need depends on the purpose and duration of your stay.
Tourism, work, study and joining family members may each have separate categories. More extensive applications may require evidence of funds, accommodation or the reason for travel. Biometric data and an in-person appointment may also be required.
For Schengen visas, a distinction is commonly made between short stays of up to 90 days in any 180-day period and longer stays. The responsible embassy or consulate can confirm which rules apply to your destination and nationality. These requirements cannot be automatically applied to other countries.
The electronic visa
An eVisa is a visa issued electronically. The application is usually completed online, with documents uploaded digitally. Some countries link the approval directly to your passport, while others provide a document that you can save or print.
The digital format says little about the level of assessment involved. An eVisa may require the same supporting documents as a traditional visa. An individual review may also take place, with timing depending on the country, visa category and personal circumstances.
The main difference between an eVisa and a traditional visa is therefore often the application process or proof of approval. An eVisa is not a global standard or a catch-all term for every travel permission requested online.
What are an eTA and ESTA?
An eTA is usually an electronic travel authorization for visa-exempt travellers. ESTA is the specific US version for travel under the Visa Waiver Program.
The electronic travel authorization, eTA
eTA stands for Electronic Travel Authorization or Electronic Travel Authorisation. It is normally used to screen travellers before departure and is electronically linked to the passport used for the application. Its exact meaning is defined by each country.
An eTA typically covers certain short stays or transit. It is not a substitute for a work, study or residence visa if your planned activity is not covered by the authorization.
For example, the United Kingdom allows certain stays of up to 6 months with its ETA. According to the UK government, the authorization generally remains valid for 2 years or until the linked passport expires. A new passport may therefore require a new ETA.
Australia also uses the term ETA. However, its rules, permitted purposes and stay limits are different. Identical abbreviations do not mean that the authorizations are interchangeable.
US ESTA
ESTA means Electronic System for Travel Authorization. The system checks whether a person can generally travel without a visa to the United States under the Visa Waiver Program.
Eligible nationals travelling by air or sea generally need an electronic passport and a valid ESTA. The stay is normally limited to 90 days and must be for an approved purpose, such as tourism, certain business travel or transit.
An ESTA is usually valid for up to 2 years or until the passport expires. Multiple trips are generally possible during that period. Changes to your passport, personal details or certain answers may require a new application.
A passport that does not meet the technical requirements for ESTA may mean that a visa is needed instead. Certain previous travel or other grounds for ineligibility can also prevent visa-free entry.
How do these authorizations compare?
The following overview shows typical characteristics. Requirements can differ because each destination sets its own entry rules.
| Authorization | Basic concept | Typical travellers | Usual purpose |
|---|---|---|---|
| Visa | Permission to enter or stay | Travellers who need a visa | Tourism, work, study or residence |
| eVisa | Visa issued digitally | People with the relevant visa category | Short- or long-term stays, depending on the country |
| eTA | Electronic pre-travel authorization | Usually visa-exempt travellers | Short stay or transit |
| ESTA | US travel authorization under the Visa Waiver Program | Eligible nationals | Travel to the United States for up to 90 days |
None of these authorizations guarantees actual entry. Border officials assess whether all conditions are met when you arrive. They may ask about your purpose of stay, accommodation or onward travel plans.
Being linked to a passport is another shared feature. You normally need to travel with the exact passport number provided in your application.
Which authorization do you need?
The right authorization depends on your nationality, destination, passport, purpose of travel, length of stay and transit route. Choosing based on the labels eVisa, eTA or ESTA alone would not be reliable.
Purpose and duration of travel
A short tourist trip is subject to different rules than studying or taking up employment. Even a business trip may be covered by a travel authorization or require a visa, depending on the activities involved.
Check which activities are explicitly permitted. Meetings may be allowed, for example, while regular employment remains excluded. An electronic authorization should never be used for a purpose other than the one stated in the application.
Length of stay also matters. ESTA travel to the United States is limited to 90 days. The UK ETA can allow certain stays of up to 6 months. These limits cannot be compared directly or automatically extended.
Our recommendation: start with the entry requirements for your destination, then identify the name of the authorization. This helps prevent a similar-sounding abbreviation from being confused with another country’s rules.
Passport and transit route
Electronic authorizations are usually assigned using your passport number. Check every letter and number carefully. A data-entry error may mean that the airline cannot find your authorization at boarding.
When you receive a new passport, the authorization linked to your old document will often no longer be sufficient. This may apply even if the original authorization has not yet expired. The rules of the relevant system always apply.
A transit stop can also trigger an authorization requirement. Key factors include whether you pass through border control, need to collect and recheck your baggage, or whether the country requires pre-travel authorization even for airport transit.
Example: A trip to Mexico with a connection in the United States may require an ESTA or visa for the United States, even if you do not plan to stay there. Check every country on your flight route, not just your final destination.
What is the difference between ETIAS, ESTA and EES?
ETIAS is a planned European travel authorisation, while ESTA is the existing US system. The EES does not grant travel permission. Instead, it records border crossings by certain non-EU nationals.
ETIAS for visa-free travel to Europe
ETIAS stands for European Travel Information and Authorisation System. It is intended for nationals of visa-exempt third countries travelling to participating European countries. Whether you will need ETIAS depends on your nationality and travel documents.
According to the European Union, ETIAS is expected to launch in the final quarter of 2026. As of 8 October 2026, the system is not yet operational. Offers made before its launch cannot represent a standard ETIAS application.
The authorisation is expected to cover short stays of up to 90 days in any 180-day period. The EU states that it may be valid for up to three years or until the passport expires, whichever comes first.
The EU currently lists an official fee of 20 euros. Fees and exemptions may change before the system launches, so confirm the current amount before submitting an application.
EES records entries and exits
EES means Entry/Exit System. It records entries, exits and certain biometric data at the external borders of the Schengen area. According to the EU, it has been fully operational since 10 April 2026.
The EES is not a visa or an electronic travel authorisation. Travellers do not apply for it in the same way as they would for ESTA or an eTA. Information is recorded as part of the border-control process.
ETIAS and EES therefore have different roles. ETIAS screens eligible visa-exempt travellers before they travel. The EES documents the actual border crossing and helps calculate permitted lengths of stay.
For travellers, digital systems mean more checks before departure and a closer link to the passport used for travel. They do not replace careful checks of visa requirements, the purpose of your stay and the permitted duration.
Which mistakes should you avoid?
Many problems are caused not by complex rules, but by confusing different systems or entering passport details incorrectly. These points are particularly important:
- Do not use eVisa as a catch-all term for every digital travel authorisation.
- Enter your passport number exactly as shown and travel with the same document.
- Check the entry requirements for every transit country as well.
- Do not rely only on the stated validity period.
- Choose consciously whether to apply directly through the relevant authority or use a service that reviews your information before submission.
Save the confirmation offline as well, even if the authorisation is stored electronically. Airlines or border officials may ask for proof. A printed copy is not required everywhere, but it can be useful as an additional backup.
Tip: Before submitting your application, compare your passport number, name, date of birth and travel purpose with your passport.
Then check that the confirmation actually relates to the document you will be using.
If an application is not approved, do not resubmit the same information without checking it first. Start by considering the possible reasons for the decision. Depending on the case, you may need a different authorisation or additional supporting documents.
What these terms mean in practice
In our view, the digital format matters less than the legal function. An online form may result in a full visa, or it may simply approve visa-free travel in advance.
An eVisa usually answers how a required visa is issued or evidenced. An eTA or ESTA, by contrast, is more about whether you may travel without a traditional visa under specific conditions.
Allow enough time for follow-up questions or additional evidence. No general processing time can be guaranteed. Even automated systems may select individual applications for further review.
An authorisation is also only one part of preparing for a trip. Depending on the destination, you may need a passport with sufficient validity, return or onward tickets, proof of accommodation and health-related documents.
How to choose the right option
First, check whether your nationality requires a visa for your destination or qualifies for visa-free travel. Then select the authorisation that covers your travel purpose and intended length of stay. Pay particular attention to the passport it is linked to and to any transit rules.
Remember: an eVisa is a digital visa. An eTA is usually advance permission for visa-free travel. ESTA is the equivalent system for the United States, while ETIAS is intended to become a European travel authorisation for visa-exempt third-country nationals.
No authorisation guarantees entry. Before every departure, check the current requirements for your own destination and personal travel circumstances with the responsible authorities.
Frequently asked questions
Is ESTA a visa?
No. ESTA is an electronic travel authorisation for eligible travel to the United States under the Visa Waiver Program. If you do not meet the requirements or are travelling for a different purpose, you may need a visa.
What is the difference between an eVisa and a visa?
An eVisa is an electronic form of visa. The application or proof is handled digitally, but the approval remains a visa. A traditional visa, on the other hand, may be applied for through an embassy or consulate, or issued as a sticker in your passport.
Do I need ESTA for the United States?
If you are travelling to the United States under the Visa Waiver Program by air or sea, you generally need a valid ESTA and an eligible electronic passport. Stays are usually limited to 90 days and must be for a permitted purpose. Eligibility depends on your nationality and individual circumstances.
Do I need a UK ETA?
Whether you need a UK ETA for a visa-free short visit depends on your nationality and travel date. For work, longer stays or other purposes not covered by the ETA, a visa may be required instead.
Does an eVisa or eTA guarantee entry?
No. Even an approved authorisation does not guarantee entry. Border authorities decide on arrival whether you meet all conditions and may enter for the purpose you stated.
How much does a travel authorisation cost?
Each country sets its own fee, and it may change. The EU currently lists 20 euros for ETIAS. For ESTA, the UK ETA or an eVisa, check the current amount on the relevant application page. If you use a service to support your application, its service fee is added separately.
