Respuesta:

{
    "codigo": "000",
    "descripcion": ""
}

El código 000 indica que todos los campos son correctos y coinciden con los registrados ante el SAT.

Código Postal Inválido:

{
    "codigo": "903",
    "descripcion": "301  CFDI40147 CodigoPostal del Receptor es disinto al que tiene el SAT"
}

Razón Social Inválida:

{
    "codigo": "902",
    "descripcion": "301  CFDI40145 Nombre Receptor es distinto a Nombre de Lista Rfc del SAT;  rfc=AAA010101AAA"
}
