Can 6x9 postcard be mailed

According to the United States Postal Service (USPS), a standard postcard must be no larger than 6 inches high x 4.5 inches wide x 0.016 inches thick. This is specified in the USPS Domestic Mail Manual, Section 123.2.

Since a 6x9 postcard is larger than the maximum allowed size, it cannot be mailed as a standard postcard. However, there are a few options you could consider:

  1. Fold the postcard: You could fold the postcard to make it smaller and within the allowed size. This might not be the most aesthetically pleasing option, but it would allow you to mail it as a standard postcard.
  2. Use a larger envelope: You could place the 6x9 postcard in a larger envelope, such as a #10 envelope (4.125 inches x 9.5 inches), and mail it as a letter. This would require a higher postage rate than a standard postcard, but it would allow you to send the postcard.
  3. Use a specialty postcard service: Some companies, like Postcrossing or Postcard Mailing Service, offer specialty postcard services that allow you to send larger postcards. These services often have specific requirements and fees associated with them.

Before mailing your 6x9 postcard, I recommend checking with your local post office or the USPS website to confirm the best option for you.
