Additional Services Linked with Shipments

We have discussed all the domestic shipping services available with the USPS; let us now consider the other services offered by the United States Postal Services that can be added to the main services. This is where the confusion about USPS begins to set in from our viewpoint.

Below is the list of additional services that apply to most postage plans and when you can use them:

  • Insurance coverage (up to $5,000): According to a customer, “I don’t really purchase protection for my items as they are very strong. I never stopped wondering about the stress that will be associated with claiming the insurance.” If the stress involved is similar to that of receiving a refund from a late Express Mail delivery, then you should be prepared to waste much of your time.
  • Registered Mail: Your items will be more secure when you ship by registered mail. The coverage for loss or damage on packages is up to $25,000. A customer had a one-time experience in using this service when he shipped some valuables across the country.
  • Delivery Confirmation: This is given for free on packages that allow you to print your shipping labels online, such as express mail and priority mail packages.
  • Signature Confirmation: If you need the recipient to sign for receipt of the package then you can purchase this service. Packages of more than $250 in value should carry signature confirmation in case there is a chargeback or any payment issue after delivery.
  • Certificate of Mailing: This service is only to show the date the package was sent out. We never used this service because it doesn’t indicate if the package gets to the recipient. You can only use this as a proof of mailing in the event of an insurance claim.
  • Certified Mail: This lets you know the delivery status of a letter. The recipient signature is also required on the letter. This service is only applicable to letters. The first and the last time we used this service was when a client was sending her taxes.
  • Return Receipt: With this service, a postcard is attached to the package you sent which the recipient must sign. It will then be mailed back to you as proof that it gets to the recipient. This works like the certified mail; only that it is not for letters.
  • Collect on Delivery (COD): The recipient pays for both the package and its shipping cost when it gets to them. Send item that requires additional or special care.

Pro Tip

Some of the advantages of shipping your boxes by mail include easy online reservation process; you might be qualified for free shipment pickup and an affordable price. Also, there is basic insurance coverage with the USPS in the event of an accident to your items while on the road.
