My questions:

1st - In case I would have to mount an array with the numbers 01000 to 19999?

2nd - How would I know if the value of the inserted in input contains in the array?

JS

var cep = '13426000';

if(arrayCeps.indexOf(cep) > -1){
   console.log('Tem no Array');
}

jQuery

if($.inArray(cep, ArrayCeps) > -1){
   console.log('Tem no Array');
}

PHP

With in_array($valor, $array) you check value.

$cep = '13426000';

if(in_array($cep, $arrayCeps){
   echo "Tem no Array";
}

With array_key_exists($chave, $array) checks keys.
