Quick answer
An ETA (electronic travel authorisation) is digital permission to travel that is linked to your passport — there is no sticker, stamp or paper document. A visa is a separate, usually more involved permission that often does produce a document or stamp. Which one you need depends on where you are going and your nationality — not on which word sounds more official.
If you've started planning a trip, you've probably seen both words used almost interchangeably. The travel page says you need an "ETA", a forum post says "visa", and a friend insists you don't need anything at all. They can all be right — for different people. Below is the plain-English version.
What an ETA actually is
An ETA is an electronic travel authorisation. You apply online, the authority screens your details before you travel, and approval is recorded digitally against your passport number. The key thing to understand: an ETA is an authorisation, not a document. Nothing gets stuck in your passport. There's no sticker to collect and no certificate you must print and carry.
Because it's tied to your passport electronically, the system "knows" your authorisation when you check in and when you reach the border. Most ETAs are quick to apply for, relatively low cost, and intended for short visits such as tourism or business trips.
You'll see ETA-style schemes under different names in different countries — for example the US ESTA and Australia's eTA work on the same principle.
What a visa is
A visa is a formal permission to enter a country, usually for a defined purpose and length of stay. Compared with an ETA, a visa is generally a bigger process: more questions, sometimes supporting documents, occasionally an appointment, biometrics or an interview. A visa often does result in something physical or formal — a sticker in your passport, a stamp, or an official electronic record you may be asked to show.
Visas tend to cost more, take longer, and cover a wider range of purposes — tourism, study, work, family visits and so on. The exact rules vary enormously from country to country.
The key differences at a glance
- What it is: an ETA is digital permission linked to your passport; a visa is a formal permission that often produces a document or stamp.
- Cost: ETAs are usually cheaper; visas tend to cost more.
- Processing: ETAs are often fast; visas can take days or weeks and may need an appointment.
- What it permits: ETAs typically cover short tourism or business visits; visas can cover a much wider range of purposes and longer stays.
- Evidence: with an ETA there's nothing to carry — it's recorded electronically; with a visa you may have a sticker, stamp or record to show.
Important: requirements depend on your nationality and where you live. Two people on the same flight can need completely different things. This guide explains the concepts — it doesn't tell you your personal requirement.
Which popular destinations use which
As a rough orientation for UK travellers:
- ETA-style authorisations: the United States (ESTA) and Australia (eTA) use electronic authorisations linked to your passport.
- eVisas: destinations such as Turkey, Egypt and India commonly use an online visa you apply for in advance.
- Visa-free (with conditions): some destinations let UK citizens enter for short stays without applying in advance — but entry rules and limits still apply.
These are general patterns and they change. Browse your destination guide and always confirm the current rule for your specific passport before you book.
How to be sure for your trip
The honest answer is that there's no shortcut around checking your exact situation. To get it right:
- Know your nationality and country of residence — both can affect what you need.
- Check your passport validity early; many countries require several months' validity beyond your travel dates.
- Confirm your purpose and length of stay — tourism, business and longer visits can have different rules.
- Apply in good time, especially for visas, which can take longer than expected.
