How to print Whatnot shipping labels (4x6 and 8.5x11)

How Whatnot labels work

Shipping is charged to the buyer at checkout, so Whatnot gives you a prepaid label for every shipment. You generate labels from the Shipments page in Seller Hub on whatnot.com and print them as PDFs. Always use the Whatnot-generated label unless Whatnot has approved you for Bring Your Own Label (BYOL); another label can stop tracking updates and delay your payout.

Before you generate labels

1. Wait until your show ends. Generating a label closes that buyer's bundle. Anything they buy afterwards, even later in the same show, becomes a new shipment with its own shipping charge. Waiting keeps eligible purchases together with Smart Bundling.
2. Check shipment details. Confirm weight, dimensions and bundles, and make a shipping adjustment if something is off.
3. Clear pending cancellation requests. You can't generate a label while one is pending. Decline it first if you plan to ship.
4. Check label settings. Confirm your return address and label size. The return address can't be changed after a label is generated.
5. Allow browser pop-ups. Labels open as PDF files.

Print labels, step by step

To print one label:

1. On whatnot.com, open Shipments and filter by Needs Label (or by show or marketplace).
2. Select the shipment and click Generate Label.
3. Select Print Shipping Label.

To print a whole show at once:

1. Filter Shipments by Needs Label, then select the orders or click Select All.
2. Under Shipping Actions, choose Generate Labels.
3. With the same shipments selected, click Export Shipping Label / Slips and choose labels, packing slips or both.
4. Pick the sort order and label size, then View & Print PDF or Send via Email.
5. Attach each label to the right package.

Packing slips are optional, but they help you check package contents and help buyers confirm their order on delivery.

Label size and printer

Label size	Printer	Good for
4 x 6 in (10.2 x 15.2 cm)	Thermal label printer	Sellers who ship every show
8.5 x 11 in (21.6 x 27.9 cm)	Any standard printer	Occasional shipping, no extra hardware

A direct thermal printer prints on heat-sensitive label stock, so it needs no ink or toner. In the print dialog, choose the 4 x 6 paper size and turn off "fit to page" scaling, or the label can shrink or split across pages. This guide does not rank printer models: choose one that supports your computer and the connection you want (USB, Bluetooth or Wi-Fi).

Weigh before you ship: carrier adjustments

Carriers weigh and measure packages after drop-off. If a package is heavier or larger than its label says, uses the wrong packaging, or is unlabeled hazmat, the carrier charges the difference. These are carrier charges, not Whatnot fees.

For US sellers, weight-based adjustments on Whatnot-generated USPS labels are charged to your Whatnot ledger for shipments sent on or after November 4, 2026. For now Whatnot still covers other adjustment types, such as incorrect dimensions and hazmat labeling. The Carrier Adjustments dashboard in Seller Hub shows each charge, the label versus measured values, and how much Whatnot covered. You can appeal an adjustment once per shipment, within 45 days of the charge; USPS decides and appeals can take up to 90 days.

To avoid them:

• Weigh items before listing and pick a shipping profile that matches; create a custom profile if none fits.
• For mystery or bundle listings, make separate listings by weight (small, medium, large) instead of one catch-all.
• Weigh the fully packed box, including packing materials, before you generate the label.
• If the weight or size changed, use Edit Shipping Details before generating the label. Whatnot covers any added cost for up to five adjustments per week, within its coverage limits.

Tools that automate printing

Printing from Seller Hub is manual. The directory lists tools that print during or right after a show:

• WhatLabels is a Chrome extension that prints item labels live during shows on Whatnot, eBay Live, PalmStreet, Poshmark and TikTok Shop Shows. It is free to add and sells in-app purchases.
• WNLabelPro prints a label as each sale closes and matches the item to the buyer's numbered box, which cuts post-show sorting. It uses a Chrome companion and a desktop app. Plans start at $25 per month per platform (prices as of 2026-11-06).
• Whatnot Autoprint is a Chrome extension that sends auction wins to a local desktop app that prints the label, with auto-print during streams, manual print buttons and item filters. No price is listed.
• Phomemo sells 4 x 6 Bluetooth and Wi-Fi shipping label printers direct from its site.

These tools read the Whatnot page or your sales data on their own; none of them is made by Whatnot. Whatnot's own Sorting Labels feature is another way to keep sold items organized. Browse all shipping label tools or the best label printing apps for Whatnot.
