How Poshmark Shipping Works (2025 Update)
Keyword: how to start reselling, side hustle 2025
Poshmark uses a flat-rate shipping system powered by USPS Priority Mail.
Here’s how it works:
-
When an item sells, Poshmark emails you a prepaid shipping label
-
The buyer pays $7.97 for shipping (you don’t pay it)
-
You package the item, print the label, and drop it at USPS
-
Tracking is automatically updated in the app
Shipping details (as of 2025):
-
✅ Up to 5 lbs per label
-
✅ Delivered in 1–3 business days via USPS Priority
-
✅ USPS pickup is free if scheduled through their site
-
❌ No UPS, FedEx, or other carriers supported
If your package weighs over 5 lbs, you’ll need to upgrade the label (more on that below).
What Packaging Can You Use on Poshmark?
You don’t need fancy branded mailers.
Poshmark lets you use free USPS Priority Mail supplies—just avoid the wrong box types.
✅ Approved boxes:
-
USPS Priority Mail envelopes or boxes
-
Plain brown boxes or polymailers
-
Recycled Amazon or retail boxes (remove old labels)
❌ Not allowed:
-
USPS Flat Rate boxes (e.g., Flat Rate Medium Box)
-
Express Mail packaging
-
Any carrier besides USPS
🧠 Pro Tip: Order free Priority Mail shipping supplies from the USPS site. They'll deliver them to your door.
How to Package Items Correctly (Without Damage or Drama)
Presentation matters, but protection matters more. Your goal is to make it pretty and secure without going overboard.
Packaging checklist:
✅ Fold your item neatly
✅ Use tissue paper or a polybag to protect it
✅ Include a thank-you note (optional, but adds a personal touch)
✅ Seal the box well with shipping tape
✅ Stick the printed label flat and clear on top
✅ Drop off or schedule a pickup within 1–2 days
🧠 Avoid overpacking. Bulky or heavy packaging can push your item over the 5 lb limit.
What If Your Item Weighs Over 5 lbs?
By default, the label covers up to 5 lbs. Here’s what to do if you’re shipping a bundle, coat, or shoes that exceed that:
Steps to upgrade:
-
Weigh your package with a digital scale (invest in a $15 shipping scale—it’s worth it)
-
Go to Order Details > Need New Shipping Label?
-
Choose the appropriate weight bracket (6–10 lbs, 11–15 lbs, etc.)
-
Poshmark will charge you the overage cost (usually $4–$10), deducted from your sale
🧠 Tip: Pre-weigh heavier items before listing so you can price accordingly.
⏱️ Shipping Timeline: When You Should Ship
Poshmark expects sellers to ship within 1–2 business days after the sale.
Faster shipping = better reviews, better chances of repeat buyers, and better exposure in the algorithm.

How to Schedule a USPS Pickup from Home
Don’t want to go to the post office? You don’t have to.
Here’s how:
-
Go to https://tools.usps.com/schedule-pickup/
-
Enter your address and package location
-
Select “Priority Mail”
-
Choose your pickup day
-
USPS picks it up for free from your doorstep
🧠 Tip: Leave a note or use a weather-safe container if you won’t be home.
What If the Buyer Doesn’t Accept the Item?
Once your item is delivered, the buyer has 3 days to accept.
If they don’t? Poshmark automatically releases your funds on Day 4.
You’ll still get paid even if the buyer doesn’t click “Accept”—as long as the tracking confirms delivery.
Common Shipping Mistakes (and How to Avoid Them)
❌ Using Flat Rate boxes
❌ Overstuffing and exceeding 5 lbs
❌ Forgetting to remove old shipping labels
❌ Delaying drop-off (which delays payment)
