 ### Error Handling (CodedError System)
-All errors use the `CodedError` protocol in `NativeAppTemplate/Common/Errors/`. Error codes use the `NATI-XXXX` prefix (NativeAppTemplate iOS) to distinguish from Android (`NATA-XXXX`).
+All errors use the `CodedError` protocol in `NativeAppTemplate/Common/Errors/`. Error codes share the `NATIVEAPPTEMPLATE-XXXX` prefix across iOS and Android.
 
 | Range | Type | File |
 |-------|------|------|
-| NATI-1xxx | App/general errors | `AppError.swift` |
-| NATI-2xxx | API/network errors | `NativeAppTemplateAPIError.swift` |
-| NATI-3xxx | NFC/scan errors | `NFCError.swift` |
+| NATIVEAPPTEMPLATE-1xxx | App/general errors | `AppError.swift` |
+| NATIVEAPPTEMPLATE-2xxx | API/network errors | `NativeAppTemplateAPIError.swift` |
 
 - New error types must conform to `CodedError` and be placed in `Common/Errors/`
 - Use `error.codedDescription` (not `error.localizedDescription`) in all error messages
 - Use `Message(error: error)` convenience to post errors to `MessageBus`
-- Error code numbers must match across iOS and Android (only the prefix differs)
+- Error code numbers must match across iOS and Android
