How to Write an Address on a Package: Where “To” & “From” Go

Addressing a package feels like it should be simpleuntil you’re standing over a box with a marker, wondering why the words “TO” and “FROM” suddenly look like they belong on a math test. The good news: carriers aren’t asking for poetry. They want a clean, scannable layout that’s easy for humans to read and even easier for machines to interpret.

This guide shows you exactly where the “To” and “From” addresses go, how to format each line (without accidentally mailing your package to an alternate dimension), and what to do for apartments, businesses, military addresses, and international shipments.

The big idea: your package needs a “front”

Every package has an “address side.” That’s the one big, flat surface where the carrier can spot the label immediatelyno scavenger hunt required. Keep your delivery address, return address, and postage/label information on the same side so scanning and sorting equipment can do its thing.

Where the “To” address goes (the delivery address)

The delivery addressaka the “To” addressgoes front and center on the package’s largest face. Think of it as the headline of your shipment. If the package were a movie poster, the “To” address is the title, and everything else is supporting cast.

Delivery address format (the clean, carrier-friendly version)

Use 3–4 lines. Keep it left-aligned (not centered like a wedding invitation). Example:

• Line 1: Recipient name (or business name)
• Line 2: Street address + unit info (APT/STE/UNIT) when applicable
• Line 3: City + state abbreviation + ZIP Code (ZIP+4 if you have it)

Business deliveries: add an ATTN line (when it helps)

If you’re shipping to a company and want it routed to a specific person or department, add an attention line above the company name. It’s basically saying, “Please don’t let this wander the building for three days.”

Where the “From” address goes (the return address)

The return addressaka the “From” addressgoes in the upper-left corner of the same address side. If delivery fails, this is how the carrier knows where to send the package back. Without it, your box may become an unclaimed traveler with a tragic backstory.

Return address format

Use the same style as the delivery address:

Optional (but helpful): a phone number for high-value shipments or international packages. Don’t replace an address line with a phone numberadd it elsewhere on the label if there’s room.

A foolproof layout (so “To” and “From” never fight again)

Here’s the classic layout most people mean when they say “Where do ‘To’ and ‘From’ go?” It’s simple, consistent, and works whether you’re handwriting or printing a shipping label.

Step-by-step: address a package like you do this every day

1. Choose the biggest flat side of the box/mailers as the “front.” (If it has a seam running through the middle, pick a different side.)
2. Put the “From” in the upper-left corner and keep it compact.
3. Put the “To” in the center, large enough to read from arm’s length.
4. Use a printed label when possible. If handwriting, use dark ink that won’t smear.
5. Keep everything flat. Don’t wrap labels around edges or tape over barcodes.
6. Double-check names, unit numbers, ZIP Codes, and street directionals (E, W, NW, etc.).

Formatting rules that prevent “return to sender” heartbreak

1) Use the right unit designator (APT, STE, UNIT)

If there’s an apartment or suite number, include itmissing unit numbers are a top-tier way to delay delivery. Put unit information at the end of the street address line when you can.

If the street line is too long, place the unit line above the street address line rather than below the city/state line.

2) Keep punctuation to a minimum

Many carriers’ automated systems do best with clean text. Skipping punctuation (periods, commas, extra symbols) can improve readability for scanners. Hyphens are typically used only for ZIP+4.

3) Make it easy to scan: clear, dark, and left-aligned

Print or type if possible. If handwriting, use block letters and keep spacing consistent. Imagine a machine trying to read your label after a long daybe kind.

Label placement: the boring detail that saves the day

Addressing isn’t only about what you writeit’s also about where you stick it. Carriers scan barcodes constantly, so placement matters.

• Place labels on the largest flat surface of the package.
• Avoid seams, corners, folds, and edges where labels can peel or wrinkle.
• Keep the barcode unobstructedno tape crossing it, no bends, no creases.
• Remove or fully cover old labels if you’re reusing a box (old barcodes confuse scanners).

Pro move: put a second copy of the address inside the box

If the outside label gets damaged, an internal slip with both “To” and “From” can help the carrier or a shipping center identify where the package should go. It’s the shipping equivalent of writing your phone number on the back of your kid’s field trip badge.

Special situations (because real life loves plot twists)

Apartments, condos, and dorms

Don’t wing ituse standard unit labels like APT or STE when you know them. If it’s a dorm, include dorm name, mailbox number, room number, and anything the school recommends.

“Care of” (c/o)

If the recipient is staying with someone else, use “c/o” on its own line or as part of the recipient line:

P.O. Boxes

For USPS deliveries, a P.O. Box is often perfectly valid. Make sure you write it clearly:

Note: Some private carriers may require a street address for certain services. When in doubt, ask the recipient what carriers can deliver to their location.

Military addresses (APO/FPO/DPO)

Military addresses follow specific formatting. The “city” is APO/FPO/DPO, the “state” is AE/AP/AA, and the ZIP Code is required. Keep it exact.

International shipping basics

International labels typically require complete sender and recipient information. Add the destination country on the last line, in English, in all caps. Many carriers also strongly prefer a phone number and/or email for delivery coordination.

Common mistakes (and how to avoid them)

• Swapping “To” and “From”: Always keep return address upper-left, delivery address centered.
• Missing apartment/suite: If there’s a unit number, include it. No unit = delays.
• Using light ink or pencil: Smudges and fading are real. Use dark ink.
• Placing label on a seam: Seams split, tape peels, labels wrinklescanners hate drama.
• Covering the barcode with tape: Some tape glare can interfere with scanning. If you must tape a paper label, keep it smooth and avoid distorting the barcode.
• Old labels still visible: Cover them completely or remove them.

FAQ

Should I write “TO” and “FROM” on the box?

You can, but you don’t have to. What matters is placement and clarity: return address upper-left, delivery address centered. If writing “TO” and “FROM” helps you stay organized, go for itjust don’t let those words crowd the actual address.

Can I put the return address on the back?

It’s not recommended. Keep both addresses on the same side so the package can be processed quickly and consistently.

What’s the best way to address a package if my handwriting is terrible?

Print a shipping label. If you must handwrite, use block letters, dark ink, and keep it simple. “Legible” beats “beautiful” every time.

Conclusion: your package deserves a clean label and a peaceful journey

If you remember only three things, make them these: (1) put the “From” (return) address in the upper-left, (2) put the “To” (delivery) address front and center on the largest flat side, and (3) keep labels flat, clean, and away from seams and edges. Do that, and your package is far less likely to take the scenic route.

Extra: Real-world shipping experiences (the “learn from other people’s chaos” edition)

If you’ve ever shipped something during the holidays, you already know: shipping is part logistics, part faith, and part “please don’t let my package spend a weekend in the wrong state.” The most common experience people report isn’t losing a package entirelyit’s watching a package get delayed because of tiny, avoidable address issues. The frustrating part is that the box often looks “basically fine” to a human, but machines and sorting systems are picky in a very unromantic way.

One classic scenario: a friend moves into a new apartment and forgets to mention the unit number. The sender writes a beautiful street address, tapes it neatly, and ships it out feeling accomplished. Then the tracking page stalls with a vague message like “Delivery attempted” or “Insufficient address.” What happened? The carrier arrived at a building with dozens (or hundreds) of doors and no clue which one belongs to the recipient. That one missing “APT 5B” turned a two-day delivery into a week-long game of customer-service phone tag.

Another common experience shows up when people reuse boxes. Reusing packaging is smart and eco-friendly, but it can backfire if old barcodes and labels remain visible. A package can get misrouted when scanning equipment catches an old code or when a worker sees conflicting information at a glance. People who ship frequently learn to treat reused boxes like witness protection: remove old labels, black out old barcodes, and make the new shipping label the only star of the show.

Then there’s the “label on the seam” incidentusually discovered after the fact. Someone tapes the label across the top flaps because it feels secure, like a belt on a suitcase. Unfortunately, seams flex, tape wrinkles, corners peel, and that gorgeous barcode becomes a wavy abstract painting. The result is often a delay while the package gets manually processed. If you ship online sales (like marketplace orders), that delay can create a domino effect: late delivery notifications, nervous buyer messages, and you staring at tracking updates like they’re a suspense thriller.

People who ship for workreturns, samples, client giftsoften develop a routine that feels almost superstitious but is actually just practical. They print labels whenever possible, keep addresses left-aligned, and do a quick “arm’s length test” (step back and see if the address is instantly readable). They also keep a habit of placing a second address slip inside the box, especially for higher-value items, because labels can get scuffed, wet, or torn in transit. That internal backup won’t prevent every problem, but it can turn a total mystery into a solvable puzzle if the outside label gets damaged.

The overall takeaway from these everyday experiences is simple: most shipping problems don’t come from dramatic, movie-plot disasters. They come from small detailsunit numbers, label placement, old barcodes, messy handwriting. Fix the small stuff, and your package has a much better chance of arriving on time, intact, and without starring in anyone’s “where did my box go?” group chat.
