eVisa vs ETA vs Digital Arrival Card: What's the Difference?

TL;DR: An eVisa is a visa applied for or issued electronically. An ETA is a country-specific permission to travel, usually used for passport holders who do not need a conventional visa, but the legal label is not universal: Australia formally calls its ETA a Subclass 601 visa. A digital arrival card is a separate immigration, customs, health, or quarantine declaration. Always check the destination's official rules for your passport and purpose instead of deciding from the acronym alone.

At a Glance

Document	What It Replaces	Who Needs It	When to Get It
eVisa	Moves some or all visa application and issuance steps online	Travelers eligible for that country's eVisa route	Follow the official processing time and earliest application date
ETA	Adds pre-travel permission under a country's own immigration rules	Passport holders covered by that ETA system	Follow the specific system's processing guidance
Digital Arrival Card	Digitizes or combines arrival, customs, health, or quarantine declarations	Travelers covered by the destination's rule; exemptions may apply	Country-specific: before travel, within a stated window, or sometimes on arrival

1. What Is an eVisa?

An eVisa (Electronic Visa) is a visa for which the application, issuance, or verification is handled electronically. Eligibility still depends on the traveler's passport, purpose, route, and the destination's rules.

Key characteristics:

It is a visa, not an arrival declaration.
Processing times, fees, permitted activities, validity, stay length, and entry points are country-specific.
Proof may be linked electronically to the passport, issued as a downloadable document, or required in printed form. Follow the issuing authority's instructions.
Approval lets you travel under that visa route but does not remove the border officer's authority to make the final entry decision.

Real-world examples:

Vietnam eVisa (valid for up to 90 days, single or multiple entry)
Cambodia e-Visa (Tourist Visa T and Business Visa E routes)

Apply through the official government portal. Commercial intermediaries may charge their own service fees and may imitate official sites. Check the current government fee and official domain before entering passport or payment details.

2. What Is an ETA?

An ETA (Electronic Travel Authorization or Authorisation) is a pre-travel permission defined by the destination's own law. The UK and the EU describe their schemes as travel authorisations for eligible non-visa nationals. Australia, however, classifies its ETA as the Electronic Travel Authority (Subclass 601) visa. The acronym alone therefore does not tell you the document's legal status.

Key characteristics:

Eligibility is tied to the passport used for the application and differs by destination.
A required ETA or travel authorisation must normally be approved before travel; it does not guarantee admission at the border.
Fees, processing times, validity, and permitted stays differ by system.
Carriers may refuse boarding when a required travel permission cannot be verified.

Real-world examples:

UK ETA — costs GBP 20, is normally decided within one day but applicants should allow up to three working days, and lasts for two years or until the passport expires.
Australia ETA — a Subclass 601 visa for eligible passports. The official app charges an AUD 20 application service fee; there is no separate Visa Application Charge. Most applicants receive an immediate result, but some cases take longer.
EU ETIAS — not operating yet. The EU says it will start in the last quarter of 2026, cost EUR 20 for applicants who are not fee-exempt, and be followed by transitional and grace periods lasting at least 12 months.

The EU's ETIAS has not launched, and the official system is not collecting applications or payments. Do not submit data or payment for ETIAS now. Apply at travel-europe.europa.eu/etias only after the European Commission confirms the system is live.

3. What Is a Digital Arrival Card?

A digital arrival card is a government arrival declaration that is separate from a visa or ETA. Depending on the country, it may replace a paper arrival card or combine immigration, customs, health, and quarantine questions in one system.

The covered travelers, exemptions, submission window, and consequences of a missing declaration are set by each destination.

Key characteristics:

It does not replace a visa, ETA, passport, or permission to enter.
Required information varies and may include passport, trip, accommodation, health, customs, or quarantine details.
Several official systems below explicitly state that submission is free, including TDAC, SGAC, Cambodia e-Arrival, and All Indonesia. Do not generalize that to every declaration worldwide.
Submission windows and exemptions are country-specific. Follow the official page rather than a universal 24–72-hour rule.
A missing declaration can cause delays or breach an entry requirement. Do not assume it can always be completed after landing.

Real-world examples:

Thailand TDAC — foreign travelers must submit it no more than three days before arrival.
Singapore SGAC (SG Arrival Card) — submit within three days, including the arrival day. Transit passengers who do not seek immigration clearance and specified residents entering by land are exempt.
Malaysia MDAC — the official form accepts trips within three days, including the submission date; check the current official exemptions.
Cambodia e-Arrival (CeA) — all travelers can submit it free within seven days before or on arrival.
Indonesia All Indonesia — since 1 October 2025, this is the integrated declaration for all international passengers arriving at Indonesian airports and seaports. It combines immigration, customs, health, and quarantine declarations, is free, and can be completed from three days before arrival or on arrival. It replaces the old EAD reference in this guide.
Vietnam health declaration — Decree 165/2026/ND-CP, in force from July 1, 2026, created the legal basis for a health declaration on entry, exit, or transit. A Ministry of Health clarification, republished by Vietnam's Consulate General in San Francisco, says this is not a routine requirement for every traveler at all times; it applies when the Ministry activates it for a specific disease situation. See Vietnam Health Declaration Rules Under Decree 165 before assuming it applies to your trip.

Since digital arrival cards require your passport data (full name as on passport, date of birth, passport number, expiry date), filling them in manually is error-prone. Review the official page carefully before submitting.

Common Mistakes and How to Avoid Them

Mistake	Why It Happens	How to Avoid
Applying for an eVisa without checking whether that visa route is needed	Confused by third-party sites	Check the destination country's official immigration website for your passport and purpose first
Skipping the ETA because "I don't need a visa"	Not knowing ETAs exist	Always check both visa requirements AND ETA requirements for your passport
Paying an intermediary for an official arrival form that is free	Scam or commercial sites imitate government forms	Confirm the official domain and fee for the specific destination before paying
Filling in the arrival card with wrong name order	Manual typos	Compare the name order against your passport and review the official page before submitting

Quick Decision Guide

Use this checklist before your next international trip:

What do the official rules require for my passport, purpose, and route?
- If a visa is required and an eVisa route is available to you, apply through the official portal within its stated timeline.
- If the destination requires an ETA or other travel authorisation for your passport, obtain it before travel under that system's rules.
Does the destination require an arrival, customs, health, or quarantine declaration?
- If yes, check who is covered, the official submission window, fee, and update procedure.
Are there other requirements?
- Check passport validity, onward travel, entry-point restrictions, vaccination or health rules, and carrier requirements on official sources. A visa, ETA, or arrival card alone never proves that every entry condition is satisfied.
