Addressing an envelope correctly might seem simple, but small details matter. Whether you are sending a personal letter, wedding invitation, business document, or formal notice, the way an envelope is written affects delivery, professionalism, and first impressions.

It is written to be practical, easy to follow, and suitable for both personal and business use. If you regularly**** buy envelopes online, getting these basics right ensures your message arrives where it should, without delays or confusion.

Envelope Address Layout: The Standard Format Explained

The standard envelope layout follows a simple structure. Keeping to this format helps postal services read and sort mail accurately.

Where the recipient’s address goes

• Centre of the envelope
• Lower half of the front side
• Left aligned text

Where the return address goes

• Top left corner
• Smaller text than the recipient address
• Optional, but strongly recommended

Standard Australian address format

1. Recipient’s full name
2. Street address or PO Box
3. Suburb, state abbreviation, and postcode

Example:

John Smith 24 Greenway Avenue Richmond VIC 3121

Avoid punctuation where possible. Australia Post prefers clean, block-style formatting with capital letters for suburb and state.

Address an Envelope for an Apartment or Suite

Apartments, units, and suites require additional detail so the mail reaches the correct door.

Correct format

1. Recipient’s name
2. Apartment or unit number, followed by street number and name
3. Suburb, state, postcode

Example:

Sarah Nguyen Unit 12 88 King Street Melbourne VIC 3000

Do not place the apartment number on a separate line unless space requires it. Keeping it on the same line as the street address reduces confusion during sorting.

Address a PO Box

PO Boxes are common for businesses and individuals who prefer secure mail handling.

Correct PO Box format

1. Recipient’s name or business name
2. PO Box number
3. Suburb, state, postcode

Example:

Buyecogreen PO Box 245 Chatswood NSW 2067

Never include a street address when sending mail to a PO Box. Choose one or the other, not both.

Can I Write “Current Resident”?

Yes, “Current Resident” is acceptable in specific situations.

When to use it

• Mail drops
• Property notices
• Community information
• Non-personal correspondence

Example:

Current Resident 15 Ocean View Road Manly NSW 2095

Avoid using this for formal letters, legal documents, or anything that requires a personal response.

Address an Envelope Without a Return Address

A return address is not legally required in Australia, but it is strongly recommended.

When it may be omitted

• Invitations where anonymity is intentional
• Pre-paid reply envelopes
• Hand-delivered mail

Risks of leaving it out

• Undeliverable mail cannot be returned
• Delays if the address is unclear
• Lost mail with no recovery option

If space is limited, a return address can be placed on the back flap of the envelope.

Address an Envelope to a Married Couple

How you address a married couple depends on formality and preference.

Traditional formal format

Mr and Mrs David Smith 45 Elm Street Toorak VIC 3142

Modern and neutral format

David Smith and Emma Smith 45 Elm Street Toorak VIC 3142

For most everyday correspondence, using both first names is widely accepted and avoids assumptions.

Address an Envelope to a Family With Children

When writing to an entire household, clarity matters.

Common formats

The Smith Family 18 River Road Ballarat VIC 3350

Or, slightly more formal: Mr and Mrs Smith and Family 18 River Road Ballarat VIC 3350

Avoid listing children’s names unless the letter specifically concerns them.

Address an Envelope to a Mother and Daughter

This is common for personal letters or invitations.

Correct format

Jane Brown and Emily Brown 72 Park Lane Glen Iris VIC 3146

If the daughter is a minor, listing the mother’s name first is generally preferred.

What’s Correct: “The Smiths” or “The Smith’s”?

This is a common point of confusion.

• The Smithsis correct when referring to the family.
• The Smith’sindicates possession and is incorrect in this context.

Correct:The Smiths

Incorrect:The Smith’s

This small grammatical detail makes a big difference in written communication.

Can I Just Write “Mom and Dad”?

Yes, but only in informal situations.

When it works

• Personal letters
• Cards from children
• Familiar family correspondence

Example:

Mom and Dad 10 Hillcrest Drive Adelaide SA 5000

For anything official or postal-sensitive, use full names to avoid delivery issues.

Address an Envelope to the Family of a Deceased Person

Sensitivity and respect are essential.

Common respectful formats

The Family of the Late John Smith 32 Willow Court Geelong VIC 3220

Or: Mrs Helen Smith and Family

Avoid using the deceased person’s name as the primary recipient unless culturally appropriate.

Address an Envelope to Someone at a Company With or Without a Name

Business mail should always be as specific as possible.

With a recipient name

Emily Carter Buyecogreen 120 Eco Way Brisbane QLD 4000

Without a recipient name

Accounts Department Buyecogreen 120 Eco Way Brisbane QLD 4000

Including a department improves internal routing within the company.

What Does “Attn” Mean and How Do I Use It?

“Attn” stands for “Attention” and directs mail to a specific person or team.

Correct usage

Attn: Warehouse Manager Buyecogreen 120 Eco Way Brisbane QLD 4000

Place “Attn” above the company name. Avoid using it for casual correspondence.

How to Use “c/o” (Care Of)

“c/o” is used when the recipient does not receive mail directly at the address.

Correct format

James Taylor c/o Buyecogreen 120 Eco Way Brisbane QLD 4000

This is common for temporary work arrangements or shared offices.

What Goes First: Job Title, Name, or Company?

Order depends on whether the letter is personal or professional.

Standard business format

Name Job Title Company Name Address

Example:

Laura Bennett Operations Manager Buyecogreen 120 Eco Way Brisbane QLD 4000

For general correspondence, the name should always come first.

Do I Need Both the Suite Number and the Company Name?

Yes, if both are relevant.

Correct format

Daniel Harris Buyecogreen Suite 4 Level 2 88 Market Street Sydney NSW 2000

Including both reduces delivery delays in large office buildings.

Address an Envelope to Doctors, Lawyers, and Other Professionals

Professional titles should be used when appropriate.

Common examples

Dr Michael Lee Ms Sarah Collins, Solicitor Professor Andrew White

Avoid overusing titles if you are unsure. When in doubt, use standard names without honourifics.
