Google API - Autocomplete does not bring ZIP

Question

I’m trying to use Google services to get addressing. The idea is to inform the address or zip code and upload the data street, neighborhood, zip code, city and state.

I was able to obtain most of the data, but the zip code is not being returned in the result. Follow the service call and the result (since I changed the key to remove, it won’t work. But the URI is ok):

            },

         ],
         "types" : [ "route", "geocode" ]
      }
   ],
   "status" : "OK"

Does the zip code not return itself? Is there any parameter that determines that the zip code needs to be included?

Answer 1

The problem with this approach is that Google location data does not always have the zip code, as you may have noticed.

Therefore, to work with Ceps, I suggest the use of Web Services like the Viacep that has a gigantic database with the Ceps of Brazil.

Unfortunately, you will have to get the information, update the fields and do validations manually, however the operation of Web Service is quite simple...

Just access the URL with the address and you will have the zip code as return.

https://viacep.com.br/ws/RS/Porto%20Alegre/Domingos+Jose+Poli/json/

[
  {
    "cep": "91790-072",
    "logradouro": "Rua Domingos José Poli",
    "complemento": "",
    "bairro": "Restinga",
    "localidade": "Porto Alegre",
    "uf": "RS",
    "unidade": "",
    "ibge": "4314902",
    "gia": ""
  }
]       

It also works the other way around: you inform the zip code and the service returns address details.

https://viacep.com.br/ws/01001000/json/

{
  "cep": "01001-000",
  "logradouro": "Praça da Sé",
  "complemento": "lado ímpar",
  "bairro": "Sé",
  "localidade": "São Paulo",
  "uf": "SP",
  "unidade": "",
  "ibge": "3550308",
  "gia": "1004"
}

For cases where a street may have more than one zip code, Viacep will return an array with all available zip codes from that street:

https://viacep.com.br/ws/SP/Sao%20Paulo/Avenida%20Paulista/json/

[
  {
    "cep": "01311-909",
    "logradouro": "Avenida Paulista",
    "complemento": "491",
    "bairro": "Bela Vista",
    "localidade": "São Paulo",
    "uf": "SP",
    "unidade": "",
    "ibge": "3550308",
    "gia": "1004"
  },
  {
    "cep": "01311-905",
    "logradouro": "Avenida Paulista",
    "complemento": "347",
    "bairro": "Bela Vista",
    "localidade": "São Paulo",
    "uf": "SP",
    "unidade": "",
    "ibge": "3550308",
    "gia": "1004"
  },
  {
    "cep": "01310-000",
    "logradouro": "Avenida Paulista",
    "complemento": "até 610 - lado par",
    "bairro": "Bela Vista",
    "localidade": "São Paulo",
    "uf": "SP",
    "unidade": "",
    "ibge": "3550308",
    "gia": "1004"
  },
  {
    "cep": "01310-933",
    "logradouro": "Avenida Paulista",
    "complemento": "2444",
    "bairro": "Bela Vista",
    "localidade": "São Paulo",
