How to Ship using United States Parcel Service
United States Postal Service has a certain protocol to be followed while shipping packages domestically and internationally. These are:
- Packing the shipment
- Preparing the shipment
- Addressing the package
- Choosing a service
- Calculate shipping costs
- Ship the package
Only upon confirming that the above-mentioned points have been covered by the shipper will USPS go ahead and ship out the package. Let’s go over the packaging protocol followed by the USPS.
Packing the shipment
While packing the shipment, choose the most appropriate box to hold the item. Make sure the box is flat when full but has enough padding to protect the contents of the package.
Size & Weight Determine Price
Packages that are unable to fit into the processing unit at the USPS shipping hub will cost more to ship, measurements need to be taken accurately in order to prepare the package so that it doesn’t get stuck and does not bulge. It is recommended not to use cord, string, or twine because it may they get caught in equipment
Preparing the shipment
Use sturdy boxes which are roomy and add some cushioning for fragile items to prevent them from moving around in the box.
Make sure the box is closed and the sides and openings are reinforced with 2-inch wide packing tape.
If you’re reusing a box, make sure the old addresses are covered or blacked out.
Packages like perfumes, alcoholic beverages, and dry ice have mailing restrictions or are prohibited. If you have any questions about what you may ship through USPS, review the restricted and prohibited items list.
Addressing the package
Make sure to address the package accordingly and that the ink used to mention the address does not smear. The package is to include the return address adn Postal codes for both the shipper and the recipient.
While addressing packages, you should make sure to follow these 2 points.
- The senders’ Address and the Recipients address should be on the same side of the box.
- It is recommended to use a permanent marker for handwritten addresses.
Choosing a service
There are many ways with which USPS sends packages out, different delivery speeds, package sizes, and extras like tracking and insurance. This depends on how quickly you want it to arrive and its size and weight.
You can ship using Priority Mail Express, Priority Mail, First-Class Package Service-Retail, Retail Ground, and Media Mail.
There are a few things to consider when choosing the right shipping service.
- Contents of the Package
- The destination address of the package
- The speed of the service
- Shape, size, and weight of the package
- USPS Tracking is available or not
- Special handling and insurance
Delivery confirmation receipts
Calculate the shipping cost
In order for the package to arrive at its destination on time, the right postage needs to be used. The shipping cost for packages with USPS depends on several factors.
Whether you are using stamps or printed postage, postage goes in the top-right corner of your package.
Make sure you’re not underpaying on postage. When a package is sent without enough postage, it may be returned to you or the person receiving it may need to pay the difference.
The USPS Price Calculator will show you how to measure your package and calculate your domestic postage costs for you.
Ship the package
USPS permits you to request for package pickups, to drop small packages in a blue collection box or to visit the nearest post office. You can drop off the package with an Approved Postal Provider. If your package weighs less than 0.81 lbs, you may use postage stamps and do one of the following:
- Put it in your mailbox for carrier pickup.
- Drop it in a blue collection box or lobby location.
- Request a free pickup.
If your package weighs more than 0.81 lbs and you’re using postage stamps, you must take it to a Post Office retail counter to send it.
NOTE: If you put it in your mailbox for pickup service, the carrier will leave it. If you drop it in a blue collection box or lobby location, it will be returned to you.
