Sort Out the Office Assistant Cover Letter Format

As an office assistant, you’ve got morning tasks to complete before the place is open for business.

Likewise— 

On medical or clerical office assistant cover letters, you must get the layout in order before the writing starts.

Here’s how to format the office assistant cover letter template:

Cover Letter Office Assistant—Format Template

• In the cover letter header, write your name and address first (top right), the date below that, and then the contact details of the company.
• Open with a standard cover letter salutation and a short-but-compelling office assistant cover letter introduction.
• Continue on by explaining why you’re the perfect fit for this office, and why this admin job is ideal for you. Present the clerical skills you bring to the table.
• Prove you’re as talented as your office assistant resume says by giving a few choice administrative achievements with verifiable numbers.
• Close off the experienced or entry-level office assistant cover letter by requesting a meeting in a captivating call to action.

Got a cover letter for an office assistant with no experience?

Keep it to no more than 200–300 words. 

If it isn’t an entry-level office assistant cover letter, a bit more is okay. However, still stay under ¾ of a page in length.

Pro Tip: Writing an office assistant cover letter with no experience? You’ll have to replace background with transferable skills. Check out our guide on writing a first-time cover letter to ensure yours works.

You see everything that goes on in the office with your eagle eye, and nothing escapes your attention.

Hiring managers sift through dozens of office assistant cover letters each day, and they also have an eagle eye.

If you don’t grab their interest from the very beginning, you’ll immediately be placed in the “pass” pile.

So, here’s how to begin cover letters for office assistant jobs:

Office Assistant Cover Letter Examples—Salutation

It all starts with the salutation.

As you can see in our above cover letter examples for office assistant greetings, we advise you to use the HR manager’s name.

Why?

Because people respond better to their own name, and that’s been proven. “To whom it may concern” seems tiring and impersonal at the same time.

If you can’t find a name, all is not lost.

Just go with something neutral, such as “Dear Hiring Manager.”

Pro Tip: Where do you find the HR manager’s name? The office assistant job description is the first place to start, of course. Next, try the company’s website. Look for an “About Us” page. Finally, search through LinkedIn.

Next up— 

The application letter introductory paragraph.

This opening statement is your first impression and an opportunity to get them hooked in just two or three sentences.

Here’s how to begin in an intriguing manner:

Cover Letter Sample for Office Assistant Jobs—Introduction

That first cover letter example is way too general— 

The hiring manager tosses generic application letters right into the bin.

The second sample cover letter opening whets their appetite. It specifies the office position you’re applying for and gives a quick look at your background.

Pro Tip: We told you that HR managers dislike universal cover letters. Instead, always tailor your cover letter to this exact office assistant job description. Want to apply at a second location? Simply write a second tailored cover letter!

Ready for a scary fact?

From 2016 until 2026, clerical assistant jobs, such as office assistants, administrative assistants, and secretaries, will decline by 5%.

To put it another way, there will be almost 200,000 fewer clerical support staff positions needed.

You’ve got to work extra hard to get this job.

But— 

Don’t worry, because if you win the employer’s heart with the body of a cover letter, you’ll avoid becoming part of these statistics.

What to include in the body section of a cover letter for office assistant jobs:

• Go into more detail on your background and administrative skills.
• Show them you meet their job requirements and company needs.
• List a few past accomplishments with numbers to prove you’re the right fit.
• Explain how everything you bring makes you a perfect match for this office.

Here are office assistant cover letter samples of a few body paragraphs:

Sample Cover Letter for Office Assistants—Body Paragraphs

At around just three paragraphs in length, the middle area of your cover letter for office assistant jobs should be brief but impactful.

Remember to use numbered wins to “show rather than tell.”

No matter if it’s a medical office assistant cover letter or one for a small legal firm, you now have a body sure to get them excited!

Pro Tip: Many job applicants for administrative support positions take these roles as simply a “job,” rather than considering moving up in the ranks. Show them you’re not a fly-by-night candidate with some brand enthusiasm and details to earn their trust.

Time to wrap up what you wrote with a nice little bow.

Here’s the right way and the wrong way to close a cover letter for both full-time or part-time office assistant jobs:

Office Assistant Cover Letters Samples—Closing Paragraph

How dull and robotic is that first one, right?

In the second example closing paragraph, however, you conclude it well— 

It restates your eagerness for the job, reiterates you have what it takes, and offers up a call for them to act.

And, we’re reaching the end— 

Now, use a closing sentiment (called a valediction) followed by your name: 

Sample Cover Letter Office Assistant—Valediction

Simple as reordering basic office supplies.

Lastly, the postscript. 

A postscript (that “P.S.” you see at the bottom of some letters) isn’t at all necessary, of course.

However, it is a creative way to mention one more thing before they make their considerations.

This is an example of a P.S. statement on an office assistant cover letter:

Sample Entry-Level Office Assistant Cover Letter—Postscript

Can you see why it’s so effective?

In this example, it reminds them of your proudest accomplishment in a cover letter containing many others. It also personally invites them to discuss further how you can help them get those same, impressive results.

Hard to resist!

Pro Tip: Ready to send off your cover letter? Not so fast! If you have time to spare, setting it aside for a day or two is an effective way of spotting errors or poor wording choices you may not have noticed on the day you wrote it.

Though it’s only a sentence or two, the closing statement has to be captivating. Make sure you get it right by following our guide: How to End a Cover Letter: Sample & Complete Guide [+20 Examples]
