A new and improved March 2016 version of Priority Mail® Label 228 makes shipping much easier for both commercial and retail customers.
The new label is:
n Approximately 1 inch larger, with total dimensions of 4¼" x 5¾".
n Vertically oriented, rather than horizontally oriented.
n Has much larger “from” and “to” section, which allows customers to write clear and complete shipping and return addresses much more easily and reduces loop mail.
Please continue to use any remaining supplies of the old labels before purchasing the new version. The updated labels will be available at the Postal Store by April 15, 2016: https:⁄⁄store.usps.com⁄store⁄.
