Hello @Sakhile you are right that using coordinates might be more useful in this case. You could try the app Wayfinder. It allows you to insert a map in your store where your customers can pin drop their delivery locations. The location and coordinates get stored in your order details. Check it out 
Topic summary
Goal: Enable customers to choose a delivery point on a Google Map and save precise latitude/longitude (GPS) coordinates instead of typing an address, due to unreliable street addressing.
Proposed solution: Use the Shopify app “Wayfinder.” It embeds a map on the storefront where customers can pin-drop their location. The app records the location and stores the coordinates in the order details, aligning with a coordinates-based delivery workflow.
Rationale: Coordinates (latitude/longitude) provide accurate delivery points when conventional addresses are incomplete or inconsistent.
Outcomes/decisions: One concrete recommendation (Wayfinder) was provided; no implementation confirmation or alternative solutions were discussed.
Status: Open/ongoing. The original poster has not confirmed trying the app.
Next steps: Evaluate Wayfinder (or similar map/coordinates apps), verify that the captured coordinates appear in orders as needed, and ensure compatibility with checkout and fulfillment processes.
