Returns:

  • (Hash<Symbol, Hash>) —

    country code to format mapping

{
  gb: { code: "GB", length: 22 },
  de: { code: "DE", length: 22 },
  fr: { code: "FR", length: 27 },
  it: { code: "IT", length: 27 },
  es: { code: "ES", length: 24 },
  nl: { code: "NL", length: 18 },
  be: { code: "BE", length: 16 },
  us: { code: "US", length: 22 } # Not standard, but sometimes used
