Benefits of Registered Mail vs. Certified Mail

The U.S. Postal Service made these mail services for two different purposes. You can learn the difference between both mail services by knowing the benefits you can get from them. 

Proof of Mailing

Registered Mail and Certified Mail provide proof of mailing services that can help customers or recipients needing this certification. 

Registered Mail and Certified Mail are more secure than regular mail, where you don’t have proof that you have mailed a package. 

In many cases, proof of mailing can help protect business owners against complaints filed by customers who claim they didn’t receive the ordered items from a store. 

Tracking and Delivery

There are two primary benefits with these delivery options. The first benefit is you have the ability to track packages throughout the shipping process. The second benefit is you have the assurance that the intended recipient receives the package.

Location Tracking

Tracking helps you monitor the status of your package during the entire delivery process. Seeing where your package is at any point in the delivery can put your mind at ease. You can also use the tracking information to communicate with your recipient to let them know that they should expect a package. 

However, Registered Mail can’t be tracked through the mail stream. You can only get your mail item’s status by requesting point-of-delivery confirmations. 

Meanwhile, Certified Mail provides tracking numbers to monitor your package throughout the delivery process. Other services have tracking, but it is cheaper with Certified Mail than as an add-on to other shipping services. 

Proof of Delivery

Proof of delivery or return receipt service confirms that USPS delivered the package. You can request to have this proof of receipt sent to you via electronic or postcard form. You’ll get a copy of the recipient’s signature, proof of billing, delivery attempt. 

Proof of delivery also helps you track the progress of your deliveries, especially if you’re an eCommerce business and rely heavily on speedy shipping services. In addition, proof of delivery is crucial when sending sensitive documents like legal papers.

You can have proof of delivery in other shipping services, but it’s an add-on that costs more than Registered and Certified Mail. 

Prioritized Delivery

Here, you will see the stark difference between Registered Mail and Certified Mail. Delivery speed is crucial for eCommerce owners, and Certified Mail is the faster service of the two. 

Certified Mail has a similar delivery speed as First-Class Mail or Priority Mail. Your recipient can get their packages in two to five days. Also, you’ll get your mail sooner when you mail your package through Priority Mail with Certified Mail as an add-on.

Meanwhile, Registered Mail has a slower delivery time because of the added security this mail service provides. Still, this service is an excellent option if you need a secure way to deliver valuable items that are not time-sensitive. 


Another added benefit of using Certified Mail is its recordkeeping feature. USPS keeps records for this mail service for up to two years. You may need this recordkeeping aspect when problems arise in the future, or there are claims where you need proof of mailing and delivery in the last two years. 

You can also access this record on the USPS website.

Labels Available on Demand

With the ability to print labels created online, you don’t have to wait in line at your local post office. You can print labels in your home and send your package to your local post office for delivery. You can get more information about the labels you need by visiting the USPS website.

Delivery Times

USPS Transit Times for Registered and Certified Mail

Certified Mail sent through Priority Mail has a quick mail delivery time. Usually, it takes 1 to 3 business days, significantly faster than other mailing services. 

Registered Mail service can usually take up to 14 days. The longer delivery time is due to the added security set in the delivery process. So, send valuable items as Registered Mail if you need a  secure way to ship sensitive packages without any time conditions. 

Handling of Valuable Items

USPS defines valuable items on its website. Here’s a broad summary of the different items regarded as valuable that can be sent via mail. 

  • Money (banknotes, currency notes, and coins)
  • Anything payable to the bearer (checks, drafts, and securities)
  • Precious metals (gold, silver, and platinum) 
  • Jewelry and precious stones
  • Traveler’s checks
