How can I add an error alert for missing house numbers in Prestige theme checkout?

Topic summary

Problem: Checkout in the Prestige theme lacks a dedicated house number field, leading customers to omit it. Request is to add a field or an error when the house number is missing.

Suggestions and trade‑offs:

  • Use Shopify’s checkout form options to show/hide fields (e.g., Address line 2 or Company) and make one mandatory. A screenshot of these settings is referenced. Consider an address correction/verification app instead of strict prompts.
  • Concern: Making Address 2 required doesn’t fix the core issue because Address 1 is still labeled “Street and House Number,” creating confusion. Ideally, Address 1 should be “Street name” and the second field “House number.”
  • Regional standards noted: Many markets (e.g., Brazil) treat house number as a separate, non‑optional field.

Workaround:

  • Repurpose Address line 2 or Company as a “House number” field, set it to required, and rename the label in the theme language editor (e.g., “Please enter house number here”).

Status: No confirmed native Shopify feature for a dedicated, validated house number field. The discussion offers workarounds but no definitive resolution.

I agree. The below reply doesn’t actually solve the problem because the first field still says “Street and House Number”, so making the Address 2 field required is just confusing for the customer unless the Address 1 field can be changed to just be “Street Name” and Address 2 to “House Nunmber”. This should be part of the basic Shopify plan… every webshop needs a proper checkout for their customers and the address is SO important for shipping.
