Order number on USPS postage shipping labels (missing)

Payments + Shipping & Fulfilment

Topic summary

Main issue: USPS shipping labels bought through Shopify Shipping suddenly stopped printing the Shopify order number, though they previously did. OP noted support initially claimed labels never included order numbers, which conflicts with Shopify’s own help documentation.

Peer report: Another merchant experienced the same behavior starting the same day.

Update/resolution: A Shopify staff member confirmed this was a brief label-creation issue that has now been resolved. Affected merchants should void labels missing the order number and recreate them to generate labels with the order number included.

Follow-up/action items:

  • Void and reprint any impacted labels.
  • Share the support ticket number with the staff member so they can review and correct the misinformation provided by chat support.

Status: Resolved; no further issues expected if labels are re-created. Unanswered item: internal review of the incorrect support guidance.

Hello,

This just started happening a couple days ago. I purchase all my postage through Shopify Shipping. I primarily use USPS. When I purchase a label via Shopify Shipping, it would print the order number on the postage label. Today it stopped doing that.

Anyone else having this issue?

I contacted Shopify via chat and the response was shipping labels never had order numbers printed on them. However, their own help doc shows that they do in fact print order numbers: https://help.shopify.com/en/manual/shipping/shopify-shipping/managing-labels/changing-and-voiding-labels

I thought it was just me. Mine started doing that today too. I have yet to reach out to support though.

Hi @hardwiretackle and @misshlee90

Thank you for sharing that feedback with us here. I looked into this and it appears that this was a brief issue with label creation that should now be resolved. You should be able to void the labels missing an order number and recreate them to fix any labels affected by this.

@hardwiretackle please feel free to share your support ticket number with me here. I would be happy to have the ticket reviewed to ensure the correct information was shared.
