如何快速确定给定邮政编码所在的州？

Question

我不需要城市或地址，只需要州。如果可能的话，我不想打 API 电话。优先考虑的是轻量级解决方案，理想情况下只是 Javascript.

我有一个用户输入 zipcode，我想根据邮政编码所在的州显示一段文本。我知道查找城市要复杂得多和状态，为此，USPS 公开的 API 可能是最好的。但是为了匹配状态，也许只是前三个数字，解决方案（我认为）应该是简单和轻量级的。

Javascript 最理想。 PHP 也可以。

Answer 1

美国邮政编码数据实际上足够稳定，如果只有州（不是需要城市或其他任何东西)。

这是一个轻量级 JS 解决方案，它采用邮政编码（作为字符串），确定正确的美国州，并且 return 将州作为其两个字母的邮政缩写。

function getState(zipString) {

  /* Ensure param is a string to prevent unpredictable parsing results */
  if (typeof zipString !== 'string') {
      console.log('Must pass the zipcode as a string.');
      return;
  }

  /* Ensure we have exactly 5 characters to parse */
  if (zipString.length !== 5) {
      console.log('Must pass a 5-digit zipcode.');
      return;
  }

  /* Ensure we don't parse strings starting with 0 as octal values */
  const zipcode = parseInt(zipString, 10);

  return st;
}

您可以 return 州的全名，而不仅仅是两个字母的缩写，方法是在最后一行 returning state 而不是 st。

您可以 return 具有范围数组的给定邮政编码的最可能状态。

这不是验证器 - 并非范围内的每个数字实际上都指定为邮政编码，将来可能会添加新的范围。

function stateFromZip(z){
    z= parseInt(z, 10);// removes leading '0'

Answer 3

zippopotam.us 有一个 REST API。这是一个如何从纯 JavaScript（无库）的 ZIP 中获取状态的示例：

var getStatebutton = document.getElementById('GetStateButton');

getStatebutton.onclick = function () {
    var zipCode = document.getElementById('ZIPCode');
    var zip = zipCode.value;
    if (!zip) return;
    var url = 'http://api.zippopotam.us/us/' + zip;
    var xhr = new XMLHttpRequest();

    xhr.onreadystatechange = function () {
        if (xhr.readyState == 4) {
            var result = xhr.responseText;
            var zippo = JSON.parse(result);
            var resultDiv = document.getElementById('divResult');
            resultDiv.innerHTML = zippo.places[0].state;
        }
    };
    xhr.open('GET', url, true);
    xhr.send(null);
};

ZIP:
<input type='text' id='ZIPCode' value='90210' />
<button id="GetStateButton">Get State</button>
<p></p>State:
<div id='divResult'></div>

或 jsfiddle 如果您愿意。

我意识到 OP 最初要求 PHP 或 JS，但我最终来到这里，所以其他人可能也会发现这很有用。

这是一个更新了邮政编码范围的 C# 版本（从 42k 邮政编码的数据库构建）

public static string GetStateFromZip(int zipCode) {
    return zipCode switch {
        var zip when zip >= 600 && zip <= 999 => "Puerto Rico",
        var zip when zip >= 1001 && zip <= 2791 => "Massachusetts",
        var zip when zip >= 2801 && zip <= 2940 => "Rhode Island",
        var zip when zip >= 3031 && zip <= 3897 => "New Hampshire",
        var zip when zip >= 3901 && zip <= 4992 => "Maine",
        var zip when zip >= 5001 && zip <= 5495 => "Vermont",
        var zip when zip >= 5501 && zip <= 5544 => "Massachusetts",
        var zip when zip >= 5601 && zip <= 5907 => "Vermont",
        var zip when zip >= 6001 && zip <= 6389 => "Connecticut",

Answer 7

在使用所提供答案的未修改版本之前，请务必考虑您的具体需求。

例如，如果您需要如下所示的“扩展”位置，您可能需要调整提供的代码以包含以下区域：

VI（维尔京群岛 https://www.zip-codes.com/state/vi.asp - 在某些答案中被列为 PR）
AE（欧洲武装部队 https://www.zip-codes.com/state/ae.asp）
AA（美洲武装部队 https://www.zip-codes.com/state/aa.asp）

这里有一些（粗略的）调整可以添加到当前接受的 Tony Brasunas 答案中：

  } else if (zipcode >= 601 && zipcode <= 795) || (zipcode >= 901 && zipcode <= 988) { // Using (zipcode >= 300 && zipcode <= 999) includes VI
      st = 'PR';
      state = 'Puerto Rico'; // https://www.zip-codes.com/state/pr.asp
 } else if (zipcode >= 801 && zipcode <= 851) {
      st = 'VI';
      state = 'Virgin Islands'; // https://www.zip-codes.com/state/vi.asp
 } else if (zipcode >= 9001 && zipcode <= 9977) {
      st = 'AE';
      state = 'Armed Forces Europe'; // https://www.zip-codes.com/state/ae.asp
 } else if (zipcode >= 34001 && zipcode <= 34095) {
      st = 'AA';
      state = 'Armed Forces Americas'; // https://www.zip-codes.com/state/aa.asp
 }
