Priority Mail is the only shipping option in my checkout

Topic summary

A store owner is experiencing an issue where only Priority Mail appears as a shipping option at checkout, despite configuring multiple UPS and USPS services in their Shopify settings.

Suggested troubleshooting steps:

  • Verify all UPS and USPS options are properly enabled in Shipping & Delivery settings
  • Confirm shipping zones correctly cover intended delivery locations
  • Check if carrier-calculated rates are filtering options based on package dimensions, weight, or destination
  • Test with different shipping addresses to identify patterns
  • Adjust default package dimensions in shipping settings

Next steps if unresolved:

  • Contact Shopify Support directly
  • Consider using third-party apps like Advanced Shipping Rules for more granular control

The issue remains unresolved and appears to involve either configuration conflicts or carrier-calculated rate restrictions.

Summarized with AI on October 31. AI used: claude-sonnet-4-5-20250929.

Even though I have chosen many shipping options from UPS and USPS, the only option my customers see is Priority Mail. I cannot figure out why.

Has anyone else had this issue?

Hi @billwiggins

It sounds like your shipping settings might have a restriction or conflict. Double-check your Shipping & Delivery settings in Shopify to ensure that all selected UPS and USPS options are correctly enabled. Also, verify that your shipping zones cover the locations you’re shipping to.

Another possible issue is that carrier-calculated rates might be filtering out other options based on package size, weight, or destination. Try adjusting your default package dimensions in the shipping settings or testing different addresses at checkout. If the issue persists, reaching out to Shopify Support or using an app like Advanced Shipping Rules can help troubleshoot further
