Gather the room list, your sale or donation plan, and a marker or printer. Write a code for each box, note what is inside and where it goes, and keep a running list that matches the labels. A labeling tool such as Packing Buddy can record photos and box codes, but the organizer decides the plan. ^[1] ^[1]

What you need before you start

Most of the work is gathering your plan before the first box is taped. Having the decisions in one place stops you from relabeling a box after it is sealed.

The sale or donation split. Which rooms or items go to the sale and which go to donation, so every box gets one destination.
A room list. The rooms or areas you are working through, so box codes match a place people can find.
Labels that stay readable. A permanent marker, or labels a printer can fill. Damp or rough cardboard can smudge a quick pen mark.
A running list. Paper or a simple sheet where every code is written next to what is inside and where the box goes.
A holding spot. Where sale boxes wait and where donation boxes wait, so the two never mix.
A contents note. Each box should say what is inside and how fragile it is, not just where it goes.

Step by step

Decide the destination before you pack. For each room or pile, state whether it goes to the sale or to donation. A box with no destination on it is a box someone opens again.
Give each box a short code. Use the room and a number, such as K-3 or M-1, so no two boxes share a name.
Write the contents on the label. List the main items and how fragile they are. This keeps an organizer from opening a sealed box to check.
Write the destination on the label. Put sale or donation, with the room code, on the side and on the top so it is seen when boxes are stacked.
Add care notes. Mark fragile, heavy, or do not stack so the people who lift the box can plan around it.
Put the same code on the running list. Match each code to its contents and destination on the paper or sheet, so the list and the boxes agree.
Check the marker holds. Write a test mark on a spare flap and let it dry, then rub it, so the label still reads after the box is moved.
Move the box to its holding spot. Keep sale boxes apart from donation boxes so nothing is sold or given away by mistake.
Recheck once the sale is set. When the date, the room layout, or the donation pickup changes, check that the labels still match the plan.

Tools that can do it

Several kinds of help fit this job. Pick based on how many boxes you have and whether you want a printed label or a handwritten one.

Markers and tape. The cheapest route. Write the code and destination directly on the box. Check that the marks stay readable on the cardboard you have.

A paper list or spreadsheet. Keep every code next to its contents and destination. Check whether it prints labels for you or only tracks the list.

A home printer with label sheets. Print the code and contents onto label paper. Check what label size your printer accepts and that the ink does not smear when the box is moved.

Your phone camera roll. Photograph each box after labeling. Check that the order of the photos matches the codes you wrote.

Packing Buddy. Packing Buddy is made by the team that publishes this site. You take photos of what goes into a moving box, and AI lists the items and picks the room. ^[1] Each box gets a code like K-03, printed on its label. ^[1] Labels print from a home printer on store-bought Avery 5163 or compatible sheets, or on plain paper you cut out and tape on. ^[1] Scanning a box's QR code with any phone camera opens that box in the browser, with no app needed. ^[1] You can search your boxes to find which box an item is in. ^[1] Share links let a partner, friends, or movers join by typing their name, with no account needed; the movers link comes with your plan. ^[1] After you sign in, AI assistants like ChatGPT or Claude can search and read your backed-up boxes, but cannot change them. ^[1] You can print blank QR labels in advance and start a box later by scanning one. ^[1] On Pro, Bluetooth label printers work in the phone app, not in the browser. ^[1] The app and its AI box lists are available in 30 languages. ^[1] It runs on phones and in a web browser; Bluetooth printing works only in the phone app, not on the web. ^[1]

Common mistakes to avoid

Packing before the destination is set. Decide sale or donation first; relabeling a sealed box takes longer than deciding first.
Writing only a date or one word. A box that says misc tells no one what is inside or where it goes.
Skipping the room code. A list of thirty boxes called box 1 to box 30 is hard to match to a room once they are stacked.
Guessing what is inside from memory. A sealed box changes contents by the time the movers arrive.
Recording the code only on the list. The label on the box and the list must agree, or the list is no help.
Mixing sale and donation in one spot. A box meant for donation can be sold, and a sale box can leave the house by mistake.
Missing fragile or heavy notes. People who lift the box cannot plan for a fragile load they cannot see.
Forgetting to recheck. A changed pickup date, a new room layout, or an added sale table can make old labels wrong.

Frequently asked questions

Where to start when labeling boxes for an estate sale?

Begin by deciding which rooms or items go to sale and which go to donation. Assign each box a short code like K-3, write the main contents and the destination on the label, and copy the same code to a running list. Place each box in the appropriate holding area. Review the labels whenever the sale date, room layout, or donation pickup schedule changes.

What should each box label say?

A good label includes the room code, the destination (sale or donation), a brief list of main contents, and any care note such as fragile or heavy. Position the code on both the side and the top so it is visible when boxes are stacked. Use identical wording on the running list to keep the list and the boxes in sync.

How to find what is inside a sealed box later?

When a label lists the contents, read it directly. Packing Buddy lets you search all boxes to locate a specific item. ^[1] For hand-labeled boxes, maintain an up-to-date running list so each code accurately reflects the contents before sealing.

Does opening a QR label on a box need an app?

No. Scanning a box QR code with any phone camera opens the box information in a web browser, without requiring an app. ^[1] This allows anyone to verify the contents by simply pointing a phone at the label. ^[1]

How much does Packing Buddy cost?

Free provides 3 test boxes per device without an account; with a free account, 10 boxes, 25 AI reads, and up to 4 photos per box. ^[1] Paid Plus costs $12.99 per month or $59 per year for up to 100 boxes; Pro costs $19.99 per month or $99 per year and includes unlimited boxes and Bluetooth printer support. ^[1]
