Thanks

  • it will not effect you, I did this and it works fine without a patch Bella – Bella Paris Aug 29 '14 at 23:29

Magento has not announced any releases to cover the changes of Sept. 7, 2014 at this time. We'll hope it's not like last year where the July 28, 2013 announcement left us scrambling over the next week to bring USPS service back online.

However, this is of concern. -> USPS API RateV3 ends on Sept. 28, 2014

Following are patches (July 2013) for Magento Community Edition to support USPS API RateV4:

If you installed these patches last year, you're done, if you installed a third party module that allowed you to use Priority Mail and Priority Mail Express with the RateV3 API (didn't install these patches) then you need to apply them before Sept. 28.

1.8.x.x can ignore the following.

Versions prior to 1.7.x.x require applying a shipping methods patch first so Magento will support USPS API RateV4. The second API Upgrade patch supports the changes to the USPS Priority Mail and Priority Mail Express postage methods.

Target Magento Release             Upgrade of Shipping Methods Patch  USPS API Upgrade Patch
                                   (if not previously applied)
Magento Community Edition 1.7.x.x  Not Required                       PATCH_SUPEE-1868_CE_1.7.0.2_v1.sh
Magento Community Edition  MAGEBP-706_CE_1.6.2.0_v4.patch     PATCH_SUPEE-1868_CE_1.7.0.2_v1.sh
Magento Community Edition  MAGEBP-706_CE_1.6.1.0_v4.patch     PATCH_SUPEE-1868_CE_1.7.0.2_v1.sh
Magento Community Edition  MAGEBP-706_CE_1.6.0.0_v4.patch     PATCH_SUPEE-1868_CE_1.7.0.2_v1.sh
Magento Community Edition  MAGEBP-706_CE_1.5.1.0_v4.patch     PATCH_SUPEE-1868_CE_1.7.0.2_v1.sh
Magento Community Edition  MAGEBP-706_CE_1.5.0.1_v4.patch     PATCH_SUPEE-1868_CE_1.7.0.2_v1.sh
Magento Community Edition  MAGEBP-706_CE_1.4.2.0_v4.patch     PATCH_SUPEE-1868_CE_1.4.2.0_v1.sh

Available from the following links:

USPS API RateV4 patch (must be applied first)


API Update Specific to


API Update for all others up to 1.7.x.x


Users of 1.7.x will probably have already installed this above patch so they could ship by Priority Mail and Priority Mail Express back in early August 2013.

If you merely installed third party modules that supported using Priority Mail and Priority Mail Express with the RateV3 calculator on 1.6.x.x and previous, you will have to apply both the Shipping Methods Patch and USPS API Upgrade Patch

  • Above is why we are adamant that no link only answers be allowed. You cannot find this information on the Magento official website as they conveniently "An eBay Inc. Company"d it out of existence with link rot. It's really sad with the official support website can't keep important stuff alive -> magentocommerce.com/blog/comments/… However, the resource download links still work, fingers x'd. – Fiasco Labs Aug 30 '14 at 6:38
