Need shipping and address labels for USPS? In this post, we will show you how to print USPS labels on your Dymo 450 printer. The Dymo Labelwriter is a direct thermal printer for efficient and fast label printing for labels up to 2.35 in. width. Hopefully, with this guide, you can learn the ropes so you can maximize what your Dymo LabelWriter 450 can do. 

Printing USPS labels require different standards on various labels, namely shipping labels and address labels. These standards should be followed to make processing time as quick and efficient as possible. 

For the Dymo LabelWriter 450, you can use these compatible labels from enKo Products. To start with, here are the guidelines for creating your address labels according to USPS. 

Guidelines for USPS Address Labels

These guidelines will show how addresses labels are printed to make sure they get delivered on time. USPS uses automated mail processing machines, so it is best to follow the format properly to prevent having delayed or misrouted mails. 

Address Format

  • Do not use symbols or punctuation
  • Use Capital Letters
  • If possible, always include the ZIP+4 Code

Recipient Address

  • Place the recipient address at the bottom center of the envelope.
  • On separate lines should be the following info:
    • Recipient’s full name/ name of the company
    • The full street address and apartment number
    • City, State, ZIP+4 Code
  • If the apartment number cannot fit on the line with the full street address, format it this way:
    • Recipient’s full name/ name of the company
    • Apartment number
    • Full street address
    • City, State, ZIP+4 Code

Sender Address

  • The sender address should be placed in the top left corner
  • Sender address should include the following, written in separate lines:
    • Sender’s full name/ name of the company
    • The full street address and apartment or house number
    • City, State, and ZIP+4 Code

Additional Tips

  • Place the postage and the address on the same side of the mail. 
  • The labels should be parallel to the longest side of the envelope
  • Use simple type fonts only
  • Format all text at left-justified
  • Print on white labels using black ink
  • Do not cut off any important information when preparing your labels
  • Keep your labels straight. Avoid placing crooked or slanted address labels.

Requirements for a USPS shipping label

Address Format

For a USPS shipping label, it is important to take note of the guidelines for USPS address labels stated above, as these standards are also followed in shipping labels. The address format for packages is the same as for envelopes. 

Another thing to point out is that the sender and recipient addresses should be on the same side of the box.

For international shipping, you need to write the delivery address in English. If there is a need to use another language, the English translation should be placed after each line. 

Label Size

The preferred label size for USPS is the standard 4×6 in. shipping label. However, this size cannot be applied to all packages, so you can go for the 6×3 or the 4×4 in. label sizes. On the other hand, for packages addressed to diplomatic or military facilities, you are required to use the 8.5×5.5 in. shipping label.

Can I Use the DYMO 450 to Print USPS labels?

You can create address labels for envelopes that you’ll send through USPS, but USPS shipping labels are too large for the Dymo LabelWriter 450. You can opt for larger printers in the market, such as Dymo LabelWriter 4XL. You can also purchase sheet labels and use an inkjet printer to create your USPS shipping labels. 

How Do I Create a USPS Shipping Label?

Creating a USPS shipping label is easy. With the use of online tools, you can print your shipping labels in the right format! We will provide you with a guide on how to use the USPS Click-N-Ship, an online shipping service that makes printing labels and buying postage easy and convenient. Here are the steps to create your USPS shipping label:

1. Go to and click on Click-N-Ship. 


2. This will bring you to the sign-in page. Sign in if you already have an account, register for a free account if you don’t have an account yet.


3. After signing in, you will be directed to the shipping label creation page. By default, the return address will be your address and information. You can edit the info in this step if there are changes needed. Scroll down to go to the next step.


4. Next, you have to set your delivery address/es. Fill out the boxes for the needed info. If you are shipping out orders of the same product with different designations, click on “Batch Order”. This will allow you to input up to 20 addresses. You can also use your Address Book on USPS if you have created them. You can learn more about this on their Address Book FAQs


5. You can also tick on “Send recipient an email notification” so that customers can be notified when the package is about to be shipped. There is also an option for “hold for Pick Up at Post Office” in case customers want to pick up their package at their nearest post office instead of having it delivered to their houses. 


6. Set the shipping date. 

7. Fill out the package details. In this step, choose whether you will ship with the flat rate or by package weight. Typically, small but heavy packages are cheaper when shipped at the flat rate option, while large but lightweight packages are better shipped by weight. To find the best option for you, you can try out both to find out what’s cheaper. 


8. For the option “Ship by Package Weight”, weigh your package and input the value. You may need to measure the package as well, in case its dimension exceeds over 12 inches. 


9. Input the package value for insurance purposes. 

10. Finally, choose your service type, either Priority Mail, or Priority Mail Express. 


11. Click on Select Service and Packaging. This will provide you with available packaging options, along with the scheduled delivery dates and their prices. 


12. Scroll down until you see the label summary. This will show the total cost of creating the label. Finally, you can click on “Add to Cart” to purchase this label ready for print. You can click on “Add to Cart and Start New Label” if you plan to create more labels. 


13. Once you add your labels to the cart, you will need to input your billing information for your labels to be purchased. 

14. After payment, you can now save your label in PDF format so you can print it on your label printer.
