Sending USPS Certified Mail® to a PO Box?

Send Certified Mail to a PO Box
Can you send USPS Certified Mail® to a PO Box?

Yes. This is a common question ask daily. You can send Certified Mail® to a P.O. Box in the United States. USPS Certified Mail® letters are addressed and delivered to the PO Box with no changes in mailers process.   In other words you just address the letter using the PO Box instead of the street delivery address.

When the USPS letter carrier delivers the letter the process that documents when the letter was received  at the delivery address is a little bit different.  A delivery notification card is placed inside the PO Box instructing the recipient they have a Certified Mail® waiting for pick up from the Post Office window clerk.  Because USPS requires someone to sign for each Certified Mail® letter the delivery notification card must be presented to the window clerk at the USPS Post Office. Then the recipient is presented the delivery confirmation Signature card and the date and time of the delivery confirmation are electronically captured and recorded by USPS.  This is how the United States Postal Service handles delivery when you address a certified mail label or form to a PO Box.


You can save time and money by sending USPS Certified Mail® by using Electronic Return Receipts a part of CertifiedMailLabels and Send Certified Mail. These labels and envelopes have been approved by USPS and do not use stickers or forms.  This makes sending USPS Certified Mail® with Electronic Return Receipt fast and easy.  The service includes proof of mailing, in-route letter tracking  and Electronic Delivery Confirmation as proof of delivery even if you send a letter to a P.O. Box.  Old fashioned Green Cards are expensive, hard to manage and can easily get mis-placed.  By addressing your letters online you can print Certified Mail® tracking numbers, bar codes and skip the trip to the Post Office!  No software to buy, no monthly costs or stickers or forms to fill out.

2012 Certified Mail Postal Rate Increase Update


The United States Postal Regulatory Commission revised and approved new 2012 USPS Certified Mail Rates  that became effective January 22, 2012.

Last year the United States Postal Service was seeking permission to increase Postal Rates in 2011.  The increase represented an average of 5.6 percent to offset the USPS losses in recent years. The Direct Marketing Association (DMA) and other businesses were concerned what impact the 2011 rate hike would have on business and became very vocal about the proposal. The Postal Regulatory Commission reached a unanimous vote declining the USPS rate increase in 2011. The reason for the decline was the lack of a solid feasible business plan for “overcoming the fundamental quandary USPS faces.” The Commission concluded the current budget problems and a number of rate cutting measures needed to be taken by USPS first.

The USPS Certified Mail Special Service rates and First Class postage rates increased the cost of sending Certified Mail with green cards to $5.75.  USPS Certified Mail letters cost is made up from three postage fees. The new 2012 Certified Mail Special Service fee costs $2.95.  Second, the Return Receipt service is available in two options.  The old fashioned green card price costs $2.35 for each letter, or the Return Receipt Electronic service can be used and costs $1.15 in place of the green card.  The third and final postage fee that makes up a USPS Certified Mail letter is First Class postage.  The one-ounce rate increased to $0.45.

Last year, in 2011 USPS Certified Mail Postal Rate Increases included the After Mailing cost to purchase the Return Receipt Electronic Signature.  This cost was proposed to increase $0.25 to $4.85 per letter.  USPS said the new postal rates must go up to help cover a potential $7 billion loss projected in 2011.  Each additional ounce of weight would also increase from 17 cents to 18 cents.

The USPS must prove “exceptional or extraordinary circumstances” in order for the new Postal Rate Increase in 2011 to the Postal Regulatory Commission (PRC) to approve prices above the rate of inflation.  The PRC will approve the request if it finds pricing above CPI to be “reasonable and equitable and necessary.” The country continues to work through the worst recession since the 1930s. Key business customers have been devastated and have withdrawn from using the mail: credit card companies, financial institutions, real estate companies, retailers.

USPS mail volume has plummeted by more than 25.6 billion pieces, or 12.7 percent, in one fiscal year. Total volume stands at 177 billion pieces.  USPS First-Class Mail is the highest revenue contributor to the Postal Service bottom line and also the fastest volume decline.

Mail volume in general has declined at a higher rate than it did following the terrorist attacks of 9/11. More and more Americans are switching to electronic alternatives, further eroding a dwindling customer base. The Postal Service seeks to balance its financial challenges against the needs of its customers through a moderate increase and to gradually increase some prices to improve their financial performance while mitigating the effect on customers.

Experts believe future price increases can be greatly alleviated if the Postal Service was deregulated and became more competitive  or given the tools necessary to be a more flexible, customer-focused: change delivery frequency, restructure the pre-payment of retiree health benefits and expand access to products and services that are more convenient to customers.

Included in this new proposal is stopping delivery of mail service on Saturday.  A significant USPS price increase is under consideration that will impact 2011 USPS Postal Rates & mailing costs including special services mail like USPS Certified Mail. This includes many of the USPS Special Services that include USPS Certified Mail with Return Receipt Requested service, USPS Certified Mail Restricted Delivery, and USPS Registered Mail.

For many consumers the initial focus or cost of mailing a First Class letter may appear to be increasing $0.02 per letter, however due to many new financial and regulatory requirements in banking, health care and lending the cost of sending compliance letters by USPS Certified Mail in 2011 could be much higher.

How long does it take USPS to deliver a Certified Letter?

Plan on 3 to 5 business days unless you send it Priority Mail 2 or 3 day service.  USPS Certified Mail provides the mailer a receipt or ‘proof of mailing’ and evidence of delivery when the letter is delivered.  It does not guarantee an exact delivery time because someone must sign for each letter.  Certified is primarily used for important notifications, compliance and business communications.  USPS Certified Mail is First Class mail with Special Services that receives priority delivery services from USPS.

Certified Mail Envelopes Security



Certified Mail Envelopes Security

Even though we do not store confidential data (USPS Address information is considered public domain information) we still protect your data using Secure Sockets Layer (SSL) banking grade data encryption. 

Secure Sockets Layer (SSL)
Secure Socket Layer is an extra level of security for online consumers. It requires you to log on through a secure server, which prevents hackers from accessing your information. SSL uses technology known as encryption. This is software that scrambles the data with secret code. You can typically tell your data has been transmitted safely when a small lock icon appears at the bottom of your browser.

When you log-in to access tracking or delivery information on our site you enable SSL encryption for your data. Even though USPS address data is considered public domain information collected by the United States Postal Service we secure all our clients data processing and reporting. At all times you data is behind a SSL-secured site encrypted banking grade firewall. Each member of your office is required to log in to the site with SSL encryption enabled, so you can share your information through confidential data access.

You are in control of setting up your passwords. Short passwords that contain a small number of characters are more vulnerable to hackers. For this reason, we require all of our passwords be at least six characters long.  

Password expiration:
To ensure maximum password security, it’s a good idea to change your password frequently. By default, users are not ever required to change their passwords. But you can require them to change passwords regularly by enabling this option.

Password complexity:
To make passwords that are easy to remember, many people create passwords that contain their name or email address, or are a string of familiar digits, such as their phone number or birthday. The problem is, simple passwords like this are easy for hackers to guess, and could compromise the security of your site. The most effective passwords do not contain parts of your name and are “complex.”

If you have highly sensitive data on your site, the administrator can ensure that all users are employing “complex” passwords. Complex passwords must meet all of the following requirements.

We suggest the password be made up of three out of four of the following:

upper case letters (A-Z)
lower case letters (a-z)
digits (0-9)

If members attempt to create a password that does not meet these requirements, they receive an error message and must create a different password before they can log in.

Never send passwords by email
When a password appears in an email message, it is a potential security loophole. For the utmost password security, you can require that passwords are never emailed

Forgot your password feature:
When a user forgets their password, the only way they will be able to access the site is for the administrator to assign a new password to the user. Users who forget their passwords will not have the recourse of using the “Forgot my password” link, as this feature functions by emailing the password to the user. For the same reason, users will not be permitted to retrieve their password by contacting to the Help Desk.

If you have any additional information about data security please contact our Director of Technology and Data Processing at 800-406-1792
