I Want Customers To Only Write Thier Pin Code..

Topic summary

A user wants to streamline checkout by having customers enter only their PIN/postal code, with country and state fields auto-populating based on that input.

Key Challenge Identified:

  • Auto-population works best for single-country stores (like Ireland-only)
  • Multi-country implementation is problematic since postal code formats vary by country
  • PIN codes alone cannot reliably determine which country the customer is in

Suggested Solution:

  • The Back4App service was recommended as a potential tool to retrieve location details from postal codes
  • Implementation would require finding a service that can handle postal code lookups

Current Status: The discussion remains open with no definitive solution for multi-country scenarios. The feasibility depends heavily on whether the store operates in a single country or internationally.

Hi @rgeafrauuhf ,

It’s a great idea to auto-populate the state and country fields using the PIN code. However, there’s a challenge when dealing with multiple countries, as each country has its own format for postal codes. This means that relying solely on the PIN code may not accurately identify the country.

If you’re focusing only on Ireland, it might be feasible to find a service that can retrieve details based on the PIN code. One option worth exploring is Back4App( https://www.back4app.com/ ), which may offer a solution that meets your needs.

I hope this helps! If it does, please like it and mark it as a solution!
