A Golang module to validate Spanish DNI (Documento Nacional de Identidad) numbers. It's a porting of the PHP library at https://github.com/ulabox/nif-validator.
It can also validate:
- NIF (Número de Indentifación Fiscal)
- CIF (Certificado de Identificación Fiscal)
- NIE (Número de Identidad de Extranjero)
go get github.com/criptalia/spanish_dni_validator
package main
import (
"github.com/criptalia/spanish_dni_validator"
"fmt"
)
func main() {
//CIF
if(spanish_dni_validator.IsValid("B65410011")) {
fmt.Println("B65410011 is valid")
} else {
fmt.Println("B65410011 is NOT valid!")
}
//DNI
if(spanish_dni_validator.IsValid("93471790C")) {
fmt.Println("93471790C is valid")
} else {
fmt.Println("93471790C is NOT valid!")
}
//NIE
if(spanish_dni_validator.IsValid("X5102754C")) {
fmt.Println("X5102754C is valid")
} else {
fmt.Println("X5102754C is NOT valid!")
}
}You can also use an import alias to make calls look prettier:
package main
import (
dni "github.com/criptalia/spanish_dni_validator"
"fmt"
)
func main() {
if(dni.IsValid("B65410011")) {
fmt.Println("B65410011 is valid")
} else {
fmt.Println("B65410011 is NOT valid!")
}
}You can also separetely validate personal and entity NIFs:
package main
import (
dni "github.com/criptalia/spanish_dni_validator"
"fmt"
)
func main() {
//CIF
if(dni.IsValidEntity("B65410011")) {
fmt.Println("B65410011 is valid")
} else {
fmt.Println("B65410011 is NOT valid!")
}
//DNI
if(dni.IsValidPersonal("93471790C")) {
fmt.Println("93471790C is valid")
} else {
fmt.Println("93471790C is NOT valid!")
}
//NIE
if(dni.IsValidPersonal("X5102754C")) {
fmt.Println("X5102754C is valid")
} else {
fmt.Println("X5102754C is NOT valid!")
}
}You can also separately validate individual NIF types:
package main
import (
dni "github.com/criptalia/spanish_dni_validator"
"fmt"
)
func main() {
//CIF
if(dni.IsValidCif("B65410011")) {
fmt.Println("B65410011 is valid")
} else {
fmt.Println("B65410011 is NOT valid!")
}
//DNI
if(dni.IsValidDni("93471790C")) {
fmt.Println("93471790C is valid")
} else {
fmt.Println("93471790C is NOT valid!")
}
//NIE
if(dni.IsValidNie("X5102754C")) {
fmt.Println("X5102754C is valid")
} else {
fmt.Println("X5102754C is NOT valid!")
}
