The returned ID structure contains:
Num- validated INN(TIN) numberIsLegal- flag indicating whether it belongs to a legal entity
Example:
package main
import (
"fmt"
"github.com/zaffka/rutax"
)
func main() {
// Parsing TaxID
id, err := rutax.ParseID("7710140679")
if err != nil {
fmt.Println("Error:", err)
return
}
fmt.Printf("INN: %s, Legal entity: %v\n", id.Num, id.IsLegal)
}The package returns the following error types:
