USPS changes effective May 31st, 2015

Applies to: AbleCommerce Gold

Release Date:  5/22/2015

Effective Date:  5/31/2015 12:01 am

Prerequisite:  For Gold versions R9 and lower.  You must have already applied the patch from USPS Changes for Sept 2014 before this one.

Severity: High (if shipping to Canada)



USPS Web Tools will be updating a few of their service names and RateV2 International API on May 31st, 2015. We have provided a patch so you can avoid any disruption in service.


Starting Sunday May 31, 2015, at 12:01AM:

  • Priority Mail International for Canada will switch to zone based pricing – there will be 7 pricing zones versus the previous single rate for the entire country.

  • The USPS will reduce the $0.01 electronic postage / meter discount to $.005 for First-Class Mail Letters (up to 3.5 oz).

  • Proposed, pending approval: First-Class Mail Parcel (Retail) becomes First-Class Package Service (FCPS), which would add a Retail pricing tier to the existing Commercial Base and Commercial Plus pricing tiers for FCPS.

  • USPS Tracking becomes free for Library Mail and Media Mail and thus USPS Tracking is included for all domestic mail classes at no additional cost with the exception of Standard Mail which has a cost of $0.36 per piece.

  • USPS will require a signature at delivery for all USPS insured shipments with an insured value of more than $500, up from $200; Signature Confirmation is included at no additional fee

Reference for more information.


Changes in this patch include:

  • Upgrade International API RateV2 to support new Shipping Origin requirement to Canada when the "USPS Priority Mail International" service is used.

  • For Gold R9 and below, we are including the fix for Issue AC8-2700 - International needs to have Mailtype changed from Package to All types.  This change is already included in all Gold R10 installs.


At the time of this writing, it is still unknown whether USPS will be making a service name change.  We will update if we get confirmation.  The change can be made manually in the \app_data\uspsmethods.csv file once USPS gives official notification.

  • Service name pending change from "First-Class Mail Parcel" to "First-Class Package Service"
