Most people expect the UK ETA form to be hard. It isn’t. It’s short. But it’s picky. One wrong letter in your passport number, or a name that doesn’t match your passport, can cause delays and stress.
The easiest fix is to gather everything before you start. This guide walks through each piece of information the form asks for, where people slip up, and how to get it right the first time.
If you’d rather skip the guessing, Apply UK ETA can guide you through each step.

The Quick Checklist
Before you open the form, have these ready:
- Your passport
- A clear, recent photo of your face
- An email address you check often
- A phone number
- Your home address
- Your job or work details
- Honest answers to a few background questions
Let’s go through each one.
1. Your Passport Details
This is the most important part. Your ETA is linked to your passport, so the details must match exactly.
You will need:
- Full name as printed in the passport
- Passport number
- Nationality
- Date of birth
- Passport issue and expiry dates
Tip: Open your passport and copy the details slowly. Don’t type from memory. Mixing up the letter “O” and the number “0” is one of the most common errors we see.
Real-world example: Imagine someone named “Muhammad Aiman bin Rosli” whose passport shows the full name, but who types only “Aiman Rosli” on the form. That mismatch can cause problems later at check-in. Always use the name exactly as it appears in the passport.
Your passport should also be valid for your whole trip. If it’s close to expiring, renew it first. You can read more on this in our requirements guide.
2. A Clear Photo of Your Face
You will be asked to upload a photo of yourself. Think of it like a passport photo, but taken with your phone.
A good photo:
- Is taken in bright, even light
- Shows your full face looking straight at the camera
- Has a plain background
- Has no hats, heavy filters, or shadows on your face
Common mistake: Using an old photo or a selfie with a filter. If the photo is blurry or dark, you may be asked to send it again, and that wastes time.
3. Your Contact Details
You will need an email address and a phone number.
Your email matters more than you think. Updates about your application go there, so use an address you check every day. Double check the spelling before you submit. A single typo means you may never see the message.
Tip: Avoid work emails you might lose access to, and avoid shared inboxes where someone else could delete messages.
4. Your Home Address
The form asks where you live. Write your address clearly and completely, including your city and country.
Keep it simple and use the same format you’d use on a parcel. No nicknames or landmarks.
5. Your Work Details
Some applicants are asked about what they do. Be ready with your job title and your employer or business name. If you’re a student, retired, or between jobs, answer honestly based on your situation.
You don’t need to write a long story. Short and truthful is best.
6. Your Travel Purpose
Why are you going to the UK? It could be a holiday, visiting family, a business meeting, a short course, medical care, or just passing through on the way somewhere else.
Picking the right reason matters, because different trips follow different rules. We explain each one on our ETA types page, including:
- Tourism or visiting family and friends
- Work, academic visits, or business
- Short term study
- Medical treatment
- Marriage purposes
- Transit through the UK

7. Background Questions
Near the end, the form asks a few personal background questions. These usually cover things like past criminal convictions and any previous travel problems, such as being refused entry to a country.
The rule here is simple: answer truthfully. If you’re unsure how to answer a question, don’t guess. A wrong or hidden answer can cause far bigger problems than an honest one. If something in your history confuses you, it’s smart to ask for help before you submit. You can reach us through our contact page.
Mistakes That Cause the Most Trouble
After looking at the questions people ask us, these are the slip-ups that come up again and again:
- Typing the passport number wrong. Check it twice.
- Names that don’t match the passport. Use the exact spelling.
- A poor photo. Dark, blurry, or filtered images get rejected.
- A wrong email address. You’ll miss important updates.
- Applying one person at a time for a family but forgetting someone. Each traveler needs their own application, including children.
- Starting too late. Don’t wait until the night before your flight.
- Rushing the background questions. Read each one slowly.

Traveling With Family?
Everyone in your group needs their own ETA, even babies and young children. Parents often fill in the form for their kids, which is fine. Just keep each child’s passport handy and double check every detail. Mixing up two passports is an easy error when you’re doing several applications in a row.
How Long Does It Take?
Filling in the form usually takes a short time if you have your documents ready. After you submit, approval time can vary. Check our page on processing time to plan your timing, and leave some extra days so you’re not stressed before departure.
A Simple Way to Prepare
Here is a quick routine that works well:
- Put your passport, phone, and a charger on a table.
- Take your photo in good light near a window.
- Write down your email and phone number so you can copy them carefully.
- Read each question slowly before you answer.
- Review everything one last time before you hit submit.
