Mercari uses the formula (to measure dimension.

Mercari Pack and Ship is a great way to ship large, bulky, or fragile items but Easyship offers up to 91% off discounted shipping rates on 250+ courier services.

Did you make a sale on Mercari? You’ve joined the 10,000+ brands that use Mercari to sell new or used products. The beauty of this online marketplace is that listing an item is free. And you only pay a 10% sales commission plus minor shipping fees.

In this article, we help you understand all Mercari shipping rates and options so that you can decide which is best for you.

Imagine you sold an iPhone using the Mercari mobile app. What happens next? Now, it’s time to send the item to the buyer.

Once your iPhone sells, Mercari suggests a list of shipping boxes corresponding to the item’s size and weight. Mercari shipping boxes come in three sizes: small, medium, and large.

If we use Mercari shipping boxes, the small box is right for the iPhone. Mercari lets you ship using boxes that meet their size and weight requirements.

If you choose Mercari Pack and Ship, you will receive a UPS shipping code via email, which you can take to a UPS Store for packaging and shipping.

This means you’re free to use your boxes and packaging. A good option would be the free shipping boxes from top courier services. However, you may prefer the ease of shipping with Mercari boxes.

Here’s a full breakdown of all the Mercari shipping options.

Choosing the right shipping service is crucial for ensuring a smooth transaction and customer satisfaction.

Mercari offers two primary shipping options: Mercari Prepaid Labels and Ship on Your Own. Understanding the pros and cons of each will help you decide which is best for your sale.

Mercari’s prepaid labels are the easiest choice for most shipments. When your item sells, Mercari automatically generates a shipping label based on the weight and size you provided and emails it to you (also accessible in the app)​

You can choose to have the buyer pay for this label (added at checkout) or offer “free shipping” (the label cost is deducted from your earnings)​

. Key benefits of Mercari labels include:

Flat-Rate Convenience & Discounts: Mercari labels have flat pricing to anywhere in the U.S. and can save up to 40% off retail shipping rates​. This means no need to calculate postage – if your package is under the limit (generally ≤50 lbs and within Mercari’s size limits), the label cost is fixed and often cheaper than retail.

Built-In Tracking: Every Mercari label comes with a tracking number that’s automatically shared with the buyer, simplifying delivery confirmation​

Shipping Protection: Mercari includes insurance on its labels at no extra charge. If a package is lost or damaged in transit, you’re covered up to $200 for most shipments (and up to $20 for First-Class Envelope)​

Using Mercari's shipping service ensures that you benefit from flat-rate convenience and built-in tracking.

No Printer? No Problem: For USPS and UPS prepaid labels, Mercari provides a QR code you can take to the post office or UPS Store. They’ll scan it and print the label for you.​

When to use Mercari Prepaid: This option is best for small to medium-sized packages within Mercari’s weight/size limits​.

It’s ideal for beginners or anyone who wants a hassle-free process and peace of mind. If your item weighs over 50 lbs or is very large (exceeds Mercari’s size limits of ~34″ on the longest side), you cannot use a Mercari label and will need to ship on your own. ​Otherwise, using Mercari’s label is usually a safe, convenient choice.

Shipping on your own means you’ll buy postage directly from a carrier (USPS, UPS, FedEx, etc.) or a third-party service and provide the tracking info to Mercari​.

While using your own shipping service can sometimes be cheaper, it requires more effort in generating labels and tracking numbers.

Mercari essentially lets you handle shipping independently, but there are important things to keep in mind:

No Mercari Insurance: If you use your own label, Mercari’s Shipping Protection doesn’t apply​. You’ll bear the risk of loss or damage. For expensive items, consider purchasing insurance from the carrier.

Provide Tracking: A valid tracking number must be entered to complete the transaction​. The sale can be canceled without tracking, even if you shipped the item. Always get a tracking number and upload it in the app when you ship.

Potential Cost Savings: Shipping on your own can sometimes be cheaper. You can shop for the best rates – for example, using third-party postage websites or regional carriers. Some sellers find that Mercari’s flat rates are higher for very light items, and they save money by buying a First Class USPS label elsewhere​. If you have the know-how to reduce cost, shipping on your own might improve your profit margin.

Use for Oversized Items or Special Services: If your package is over Mercari’s weight/size limits or you need a service Mercari doesn’t support (e.g., shipping to APO/FPO, or using a special courier), you’ll have to ship on your own. For example, items over 50 lbs must be shipped on your own​. .

When to ship on your own: This option is great for experienced sellers looking to save on postage or when your item doesn’t qualify for Mercari’s labels. Just remember that you’ll need to handle all aspects of shipping (label purchase, any claims, etc.) yourself. If you choose this route, double-check addresses and pack carefully since you won’t have Mercari’s insurance safety net.

Proper packaging protects your item so it arrives in perfect condition. It also ensures you meet Mercari’s packing guidelines (which is important for Shipping Protection). Here are best practices for safely packaging different types of products:

Shipping fragile items requires extra care:

Use a Sturdy Box: Choose a rigid, new or like-new cardboard box that leaves 2–3 inches of space on all sides of the item for cushioning​. If the item is heavy or very delicate, consider double-boxing: place the item in one box, then pad that box inside a larger box​.

Wrap Thoroughly: Wrap each fragile piece individually in bubble wrap (at least 2–3 inches thick)​. Pay special attention to corners and delicate parts. For example, glassware should be wrapped and packed upright if possible, and electronics should be protected from all angles.

Fill Empty Space: Surround the item with plenty of cushioning material – packing peanuts, crumpled paper, air pillows, foam, etc. The goal is to prevent any movement inside the box​. After packing, gently shake the box; if you feel or hear the item shifting, add more filler until it’s snug.

Seal and Label: Tape the box securely on all seams (the “H” taping method works well)​. Consider marking the box “Fragile” on multiple sides. While carriers don’t guarantee special handling, a “Fragile” label alerts them to be more careful​.

Heavier items need strong packaging to withstand handling:

Reinforce the Box: Use a double-walled box or reinforce a regular box with extra tape on the bottom seams to support the weight. The box should be robust enough that it won’t tear or burst. If reusing a box, ensure it’s not weakened from prior use.

Padding and Placement: Like fragile items, heavy items should have cushioning on all sides to absorb shock. Use dense materials like foam sheets or multiple layers of bubble wrap. If the item has parts that could shift (for example, a heavy electronic with a removable component), secure or pad those parts separately.

Weight Limits: Remember Mercari’s carrier weight limit is 50 lbs for prepaid labels​. Ensure the package (item + packing) is under this. If it’s slightly under 50 lbs, don’t skimp on padding just to stay under – it’s safer to go over and ship on your own than risk damage. Also be mindful of dimensional weight for large bulky boxes (more on that in section 3).

Leverage Pack and Ship: For large, bulky items (like a guitar or stroller), Mercari offers “Pack and Ship” through the UPS Store, where professionals pack the item for you​. This costs extra, but it can be worth it for heavy items that are hard to pack.

Items that don’t fit neatly in a standard box (odd shapes or dimensions) can be challenging:

Find the Right Container: Look for a box or mailing tube closest to the item’s shape. If needed, you can Frankenbox (combine boxes): cut and re-tape boxes to create a custom size, ensuring all seams are well-secured. The item should not press against the box walls – give it some cushioning space.

Disassemble if Possible: If the item can be removed (e.g., a lamp shade removed from the base, furniture legs detached), do so. Pack components separately within the box, with padding in between. This not only makes the shape more regular, it also reduces the chance of parts poking through the package.

Generous Padding: Irregular items often have protrusions or delicate points. Wrap the entire item in bubble wrap, then pad any pointy or delicate sections with extra foam or cardboard. For example, wrap the ends of a curved item with foam pieces to create a buffer. Fill all gaps in the box with cushioning so nothing shifts.

Consider Professional Packing: If you’re unsure about packing an oddly-shaped, valuable item, using Mercari’s UPS Pack and Ship service might be wise​. They will pack it securely for you. Otherwise, take your time and use plenty of packing material to ensure the item is immobilized and protected.

Use appropriate packaging materials – poly mailers or padded envelopes for durable soft goods and boxes for most other items​.

Remove or cover any old barcodes or labels on reused boxes​.

Seal every opening with tape​.

It’s also smart to photograph the item after it’s packed and sealed​.

This documents the condition and packaging in case of any issues during transit.

Finally, include a small thank-you note for the buyer – it’s a nice personal touch!

Accurate weight and dimensions are crucial for avoiding surprise shipping fees. Carriers charge based on whichever is greater – the actual or the dimensional weight (a calculation of package volume). Here’s how to get it right:

Use a Reliable Scale: Weigh your item after it’s fully packaged since the box and packing material add weight. A small digital postal or kitchen scale works for most packages. For heavier items, you may need a larger scale.

Measure Dimensions: Use a tape measure to record the package's length, width, and height. Mercari (and carriers) use these to calculate dimensional weight. The formula Mercari uses is (L x W x H) ÷ 139​

Compare to Label Limit: Check that your package’s weight and size do not exceed what you selected when listing. Mercari’s standard label limits are ≤50 lbs and no side longer than 34 inches​. Mercari lets you edit the label weight on the Order Status page.

By weighing and measuring carefully, you’ll pick the correct shipping option and avoid surprise costs. It only takes a minute and will save you money and hassle.

Once your item is sold and packaged, it’s time to label it for shipment. Follow these steps to generate, print, and attach your shipping label:

Generate/Obtain the Label: If you’re using a Mercari prepaid label, it’s generated automatically after the sale. You’ll find it in your Mercari app under the order details (Order Status page), ready to download, and Mercari also emails it to you​. Select the label in the size format you need (usually PDF that fits 8.5″x11″ paper by default). If you opted to ship on your own, you must purchase postage from your chosen carrier. Enter the buyer’s address exactly as provided by Mercari to create a shipping label and pay for the appropriate postage.

Print the Label: Print the label on a standard printer or a label printer. Black and white is fine – just ensure the barcode is clear. You can print on paper, tape it on, or use self-adhesive shipping labels. (Most office supply stores or libraries can print for you if you don’t have a printer at home.)

Tip: Mercari offers a QR code for USPS or UPS shipments, which you can have scanned at the post office/UPS Store to get a label printed for free​. This is super handy if you can’t print yourself.

Attach Securely: Affix the label to the top of the package (the largest, flattest surface)​. If using paper, tape over all edges so it doesn’t peel off. Do not cover the QR code or barcode with opaque tape.

Double-Check Details: Before sending, verify that the label shows the correct destination and return address (Mercari’s prepaid labels use Mercari’s return address for you). Ensure it has the correct weight class that you paid for.

With your package all set to go, the final step is handing it over to the carrier. Mercari gives you flexibility here – you can drop off packages yourself or even schedule a home pickup in some cases. Here’s how to complete the ship-off:

Drop-Off at Carrier: Take the package to the appropriate shipping carrier location. If you used a Mercari label, the carrier is noted on the label (e.g., USPS, UPS, or FedEx). Bring it to that carrier’s drop-off – do not drop a UPS package at a post office or vice versa, as it won’t be scanned and will cause delays​

Confirm Shipment in Mercari: As soon as you’ve dropped off the package, go to your Mercari Order Status page and tap “Confirm as Shipped” (or “Confirm Shipment”)​ Mercari will prompt you to verify you’ve shipped it. This step notifies the buyer that the item is on its way. (If you used a Mercari label, tracking will update automatically after the carrier scans it. If you shipped on your own, confirming shipment is extra important so the buyer knows you sent it.)

Scheduling a Pickup: If you can’t get to a drop-off location, you may be able to have the carrier pick up the package from your home.

Mercari makes tracking easy, but it’s important to understand how it works and what you may need to do:

If you used a Mercari prepaid label, the tracking number is automatically linked to the order. You can view it on the Order Status page, and the buyer can see the tracking updates on their end as well.

If you shipped on your own, you must input the tracking number in the Mercari app​. Go to the Order Status, tap “Add Tracking” (or similar), and enter the number and carrier. This step is crucial to completing the transaction. Mercari requires a valid tracking number for all sales​.

As the seller, monitor the tracking status until it shows delivered. This protects you in case something goes awry. If you notice no update a few days after drop-off (e.g., it hasn’t been scanned), you might contact the carrier or check with the drop-off location.

Buyers can track via Mercari, but it’s good practice to communicate, especially for longer shipments. Send a polite note like, “Hi! I shipped your item, and the tracking number is 9405… It’s on its way via USPS. Let me know if you have any questions.”

Mercari will notify you when the item is delivered (based on tracking). The buyer is then prompted to rate the transaction. If 24 hours pass after delivery and the buyer hasn’t rated, Mercari may auto-complete the sale. At that point, your funds will be released.

A tracking number might occasionally not update for several days, especially with USPS. If no update occurs for an unusual time (e.g., a week with no scans), you can contact Mercari Help or the carrier to investigate.

Even with careful packing and prompt shipping, issues can occasionally arise – a package might get delayed, lost, or damaged, or a buyer might report a problem. Here’s how to handle common shipping issues professionally and efficiently:

Delayed Shipments: If the tracking shows a package is taking longer than expected (e.g., no movement for several days or stuck in transit), communicate with the buyer. Most buyers are understanding if kept informed. Provide the tracking number and ask for an update.

Lost and Damaged Packages: A package is considered “lost” if it never shows delivered and has stopped updating in tracking. If you used a Mercari prepaid label, you’re covered up to $200 for loss in transit​ or damage.

Returns and Disputes: If a buyer opens a return claiming the item is not as described or arrived damaged, Mercari will put the transaction on hold. Provide any evidence (photos, packing method, etc.) to Mercari to help your case.
