IELTS Writing Task 1 Letter Addressing Errors Checker Guide

Here's what kills your score without you writing a single wrong word: you mess up the letter opening. The address line, the salutation, the way you greet the recipient—these tiny details cost you band points. Examiners spot it immediately when your letter doesn't follow formal conventions, and they dock you for it.

This guide walks you through every addressing error students actually make, shows you exactly how to fix them, and gives you a checklist you can use before you submit. Use our free IELTS writing checker to catch these mistakes instantly.

Why Letter Addressing Errors Tank Your IELTS Writing Score

IELTS Writing Task 1 is worth 50% of your writing band score. Within that section, your ability to match register and format directly affects your Task Response score. The official band descriptors are explicit: Band 7+ responses "use appropriate conventions for the letter format chosen." Band 6 shows some errors. Band 5 shows significant mistakes.

That's the difference between passing and failing for most students.

A misplaced comma in your salutation isn't just a typo. It's proof you don't understand formal English conventions. Examiners see it as a lack of control over register. You get 20 minutes for Task 1. Spend 30 seconds checking your greeting. It's time well spent.

What Are the Three Critical Letter Addressing Elements in IELTS?

Every formal letter in IELTS writing requires three addressing components examiners check. First, your address (the sender's address) goes at the top left. Second, the date appears below it in the correct British format. Third, the recipient's address and salutation must follow formal conventions. Skip any of these, and you signal to the examiner that you're not familiar with formal letter structure. This isn't about being picky. It's about showing you can control formal written English.

Sender's Address: The Line Most Students Skip

Most students skip their own address. Don't. Put it at the top left. You don't need to write your full name above it; the address alone is enough. Keep it simple, realistic, or believable. You can use a fictional address; examiners aren't checking your residency.

See the spacing? That's intentional. It makes the letter readable and shows you understand professional format.

Date Formatting: Two Correct Options, Both Done Wrong Often

You have two correct options for the date in British English. Use either "19 April 2026" or "19th April 2026". Both work. What doesn't work? "04/19/2026" (American style), "19-04-2026" (ambiguous), or leaving it out entirely.

The date goes on its own line, below your address and above the recipient's address. Leave exactly one blank line before the recipient's details. One. Not two, not three.

This is where most students slip up. They either use the wrong date format or mess up the spacing. Both hurt you. When you use our IELTS writing checker, these formatting errors get flagged immediately.

How Recipient's Address Changes Your IELTS Letter Salutation

The recipient's address goes below the date. You need at least the position or name and the organization. A full street address is a bonus but isn't always provided in the task. Here's what determines how you greet them: if you know the person's name, use "Dear Mr Smith" or "Dear Ms Johnson". If you only know the position, use "Dear Manager" or "Dear Sir or Madam". For business letters to a company, use the position if available. Capital letters, no commas after the name in the salutation. "Dear Mr Smith," not "Dear Mr. Smith,". British English doesn't use periods in titles.

The Salutation: Where Nine Out of Ten Students Fail

This line tells the examiner everything about whether you understand formality in English. Get it wrong, and your Coherence & Cohesion score suffers immediately.

Match the salutation to what you know about the recipient:

• "Dear Mr/Ms [surname]," if you have a specific name
• "Dear Sir or Madam," if you don't know the person's name or gender
• Never use "To Whom It May Concern" (it's obsolete)
• Never use "Hello" or "Hi" in formal letters
• Never use "Dear Sirs and Madams" (awkward and wrong)

The comma after the name is non-negotiable. British English requires it. Miss this comma? The examiner notices. Your Grammatical Range & Accuracy score drops.

The Sign-Off: Just As Critical As The Opening

You nail the greeting, then destroy it with a sloppy closing. The sign-off is the last thing the examiner reads before your name. It matters.

Match your sign-off to your salutation. This is a rule, not a guideline:

• If you used "Dear Mr/Ms [name]," close with "Yours sincerely,"
• If you used "Dear Sir or Madam," close with "Yours faithfully,"
• Both are formal and correct for IELTS

Then leave a line and write your name. Don't include your address again. Just the name. Done.

Real IELTS Task 1 Examples: How to Apply These Rules

Let's look at actual IELTS writing test scenarios and the correct addressing format.

Example 1: "You want to complain about poor service at a restaurant. Write a letter to the restaurant manager. You do not need to include the sender's address. Begin your letter as follows: Dear Sir or Madam,..."

The task tells you the salutation. Use it exactly as written. Your letter starts there. The examiner has set the register for you. Don't change it. If you need help matching the right tone to your complaint, check out our complaint letter tone checker guide.

Example 2: "Write to the Head of Customer Service at a mobile phone company about a billing error. You know the company's name but not the person's name."

Your recipient address:

Why "Sir or Madam"? You don't know the person's gender. This choice is safer and equally formal.

Example 3: "Write to Dr. Emma Harris, the accommodation officer, about your housing problem."

Note: No period after "Dr" (British English). Use the title and surname. Your closing will be "Yours sincerely,".

IELTS Letter Addressing Errors Checklist: Use This Before You Submit

Print this checklist and use it every time you write a Task 1 letter. Check off each item before submitting:

• Sender's address at the top left (or omit if the task says so)
• Date in correct format: "DD Month YYYY" (e.g., 19 April 2026)
• One blank line between each section (address, date, recipient address, salutation)
• Recipient's address includes position and organization name
• Salutation matches what you know: specific name or "Sir or Madam"
• Comma after the salutation: "Dear Ms Jones," not "Dear Ms Jones"
• Closing matches salutation: "Sincerely" for a known name, "Faithfully" for unknown
• Your name on the final line, no address
• No abbreviations in dates (write "April" not "Apr")
• No American date format (not 04/19/2026)

You've got 20 minutes for Task 1. Two of those minutes should go to checking this list. It's the difference between Band 6 and Band 7. For a complete breakdown of other common IELTS writing task 1 errors, try our letter format checker guide.
