Go CNPF TestsGoDocGo version

A Go module to validate CPF and CNPJ numbers (Brazilian people andcompanies unique identifier for the Federal Revenue).

The pseudo-acronym CNPF is a sort of tong-twister and a common typo when developers discuss the implementation of objects that could hold either a CPF or a CNPJ numbers.

package main

import "github.com/cuducos/go-cnpf"


func main() {
	// these return true
	cnpf.IsValid("23858488135")
	cnpf.IsValid("238.584.881-35")
    cnpf.IsValid("11222333000181")
	cnpf.IsValid("11.222.333/0001-81")

	// these return false
	cnpf.IsValid("111.111.111-11")
	cnpf.IsValid("11.111.111/1111-11")
	cnpf.IsValid("123.456.769/01")
	cnpf.IsValid("12.345.678 9012-34")
    cnpf.IsValid("ABC.DEF.GHI-JK")
    cnpf.IsValid("AB.CDE.FGH/IJKL-MN")
	cnpf.IsValid("123")

	// these returns 11111111111 and 11111111111111
    cnpf.Unmask("111.111.111-11")
	cnpf.Unmask("11.111.111/1111-11")

	// this returns 111.111.111-11 and 11.111.111/1111-11
    cnpf.Mask("11111111111")
	cnpf.Mask("11111111111111")	
	
}
