Don’t Forget: USPS® Price Changes Take Effect This Weekend!

Presort.com   January 15, 2016    

As we told you in an earlier e-Tip, the Postal Regulatory Commission (PRC) approved all of the United States Postal Service® (USPS®) proposed price increases. The implementation date for these approved prices is January 17, 2016.

Again – the final implementation date for these price changes is January 17, 2016. That’s this Sunday! 3 days from today!


Overall Changes

The new prices are available in Excel and .csv format on thePostal Explorer web site. The draft postage statements are also available on the same web site. Please note that this price change does not impact all mailing classes, so for some mailings the new January 2016 postage statements will be required, whereas for other mailings, the current May 2015 postage statements may still be used.


Software Updates

If you have not already done so, mailers will need to update their mailing and shipping software to accommodate these new prices. There is no new Mail.dat® file format specification version associated with this price change. Here is what will be supported as of January 17th:


January 17, 2016

  • USPS will support Mail.dat 14-2 Errata versions and 15-1 Errata
  • USPS will continue to support all Mail.dat 14-2, errata versions including
  • USPS will continue to support all Mail.dat 15-1, errata versions including

As a reminder – there was a mandatory PostalOne! update on January 3, 2016, which means that if you are a mailer who submits eDoc, you should have downloaded and installed the new USPS MD Client software on the 3rd.

IMPORTANT NOTE: PostalOne! will be releasing a patch to the MD Client software on Sunday, January 17, 2016. This patch is to correct issues with Mail Anywhere submissions, so if you submit Mail Anywhere mailings, you will need to download and install this patch. This is not a mandatory update, so non-impacted mailers are not required to download and install this patch, but are encouraged to do so.


Is There Anything Else?

Of course there is! In addition to the price changes, the USPS is offering the following five (5) new incentives/promotions this year:
