Marketplace shipping labels: the platform's label or your own

What carrier does Depop use, and can you still ship on your own?

Depop uses USPS: Depop Shipping in the US is a USPS label, and since October 28, 2026 it is the only shipping method for new Depop listings.

Depop's US help page says the Other method, where you bought your own label, is closed to new listings from that date; a listing set to Other earlier keeps it until it sells, and relisting it moves it to Depop Shipping. You print Depop's label or show the QR code from the sale email at a USPS drop-off, and tracking fills in on its own. Ship a Depop Shipping order some other way and Depop says you lose Depop Protection for sellers and the order may be cancelled.

Our shipping labels for Depop sellers page and the how Depop shipping works post compare Depop's label with your own; since October 28, 2026 that applies only to listings still set to Other.

When is your own label the better fit for a marketplace sale?

Your own label fits when the platform allows one and your parcel is not the parcel the platform's label was priced for: a light item on a label sized for heavier ones, a heavy or bulky item, or a seller shipping several marketplaces at once.

Platform labels are priced in steps set before the sale: Mercari's label states a weight the packed box must not exceed, and Poshmark's covers parcels up to a set weight, with paid upgrades above it. A label you buy yourself is quoted on the packed parcel's actual weight, size and destination, so the further a parcel sits below the top of its step, the more a live quote has to work with. How the three carriers' economy ground services compare by weight is in USPS vs UPS vs FedEx economy ground services.

Cross-listers gain the most from one workflow: one queue, one wallet and one ledger instead of a label flow per platform, as selling on multiple marketplaces with one shipping queue lays out, with the reseller version in shipping labels for vintage and thrift resellers.

For awkward parcels, Mercari sets a size and weight ceiling on its prepaid label and charges extra above it, and Whatnot opens Bring Your Own Label in the US only to approved sellers in its Wholesale category. Weigh and measure the packed box first: how to weigh a package and package size and weight limits cover both. Where the platform requires its label, or its protection is worth more to you than the price gap, the platform's label is the right call.

Who pays when a carrier re-weighs a marketplace parcel?

The seller pays: on the platform's label the marketplace can pass the carrier's overage on to you, and on your own label the adjustment goes to whoever bought the label.

Poshmark's Shipping Policy makes packages that miss USPS label standards, including actual and dimensional weight, the seller's responsibility and lets Poshmark charge the carrier's overage fee to the seller. Mercari says extra shipping charges after a weight change are the seller's, and Whatnot tells Bring Your Own Label sellers they pay any difference between their label and the shipping collected at checkout.

On a GoatLabels label, a carrier adjustment posts to your prepaid wallet as its own dated ledger line, next to the label it belongs to; what triggers one is in carrier billing adjustments. The habit that prevents most of them: weigh the packed parcel and measure the box before you buy.

What does a USPS Ground Advantage parcel under 1 lb cost?

At USPS retail prices, a Ground Advantage parcel under 1 lb costs one of two amounts per zone: the 4 oz and 8 oz tiers share a price, and the 12 oz and 15.999 oz tiers cost the same as a full pound.

These are the Notice 123 prices effective October 4, 2026, USPS's holiday list until 12 a.m. CT on January 17, 2027. USPS's Commercial price list has had one price per zone for every tier up to 15.999 oz since July 12, 2026, as the last row shows.

From the USPS Notice 123 Price List, effective October 4, 2026, read November 9, 2026; ounce tiers from the USPS Ground Advantage page; the Commercial change from the Federal Register notice effective July 12, 2026.

Example: a 9 oz tee in a poly mailer is billed at the 12 oz retail tier, the same retail price as a full pound; repacked to 8 oz in a lighter mailer, it drops to the 8 oz row, one retail step lower in every zone in the table.

Published USPS prices, fees and service windows are a benchmark, not what a GoatLabels label costs: a GoatLabels quote is one price per rate for your packed parcel, shown before you buy. The full grid from 4 oz to 70 lb is on USPS Ground Advantage rates.

Do eBay sellers need a paid postage service to print labels?

No: eBay Labels prints USPS, UPS and FedEx labels inside eBay and charges each one to your eBay funds or the payment method on file, and eBay's help page names no subscription for it.

Stamps.com, by comparison, lists three monthly plans and a trial on its pricing page, none of them free (checked November 9, 2026).

A Ship with eBay listing, open to individual sellers on eligible items, comes with a prepaid label eBay says you must use for the item to be protected. Elsewhere you add your own label's tracking in Seller Hub, and for item-not-received protection it must come from an eBay-integrated carrier and show an acceptance scan (eBay tracking help); one in-transit protection stays with eBay's own labels (eBay seller protections, read November 2, 2026). The rest is on shipping labels for eBay.

How does GoatLabels fit each marketplace?

GoatLabels prints the label wherever a marketplace lets you bring your own: eBay and Etsy orders sync in through store connectors, and other platforms' orders come in by CSV, the API, or a pasted order the in-app assistant drafts a label from.

• eBay and Etsy: store connectors sync orders into one To Ship queue and send tracking back; see eBay shipping labels and Etsy shipping labels.
• Mercari: your own UPS, USPS or FedEx label, without Mercari Shipping Protection; see Mercari ship on your own.
• TikTok Shop: USPS stays in TikTok Shipping (since January 2026), and GoatLabels quotes UPS and FedEx for shops with Seller Shipping enabled; see TikTok Shop shipping labels.
• Whatnot: approved Bring Your Own Label sellers only; see Whatnot shipping labels.
• Facebook Marketplace: the Facebook pages we read do not say whether a Marketplace order can ship on your own label, so check before you buy one; see Facebook Marketplace shipping labels.
• Depop: listings still set to Other; see shipping labels for Depop sellers.
• Poshmark: not Poshmark orders (heavy boxes: the Poshmark label weight limit); a reseller's other sales: shipping for Poshmark resellers' other channels.
• Temu: self-fulfilled orders by CSV or the API; see Temu seller shipping labels.
