如何快速确定给定邮政编码的状态
How can I quickly determine the State for a given zipcode?
我不需要城市或地址，只需要州。如果可能的话，我不想调用API。优先考虑的是一个轻量级的解决方案，最好只是Javascript。
我有一个用户输入的zipcode，我想根据邮政编码所在的状态显示一段文本。我知道查找City和state要复杂得多，因此像USPS公开的API可能是最好的。但为了只匹配状态，也许只在前三个数字上，解决方案（我认为）应该简单而轻便。
Javascript是理想的选择。PHP也可以工作。
美国邮政编码数据实际上足够稳定，如果只需要State（而不是City或其他任何东西），则无需点击API或数据库即可完成此操作。
这里有一个轻量级的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，并将该州作为其两个字母的邮政缩写返回。

您可以通过在最后一行返回state而不是st来返回州的全名，而不仅仅是两个字母的缩写。
非常感谢@kevin boucher和@abaldwin99在解析较小的新英格兰代码方面提供的帮助，并在这里给出了他们的答案，避免了可怕的八进制评估错误。
此外，感谢您将大部分原始代码转到这个有用的页面。

zippopotam.us有一个REST API。以下是如何在纯JavaScript（无库）中从ZIP获取State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>或者在jsfiddle，如果你喜欢的话。
您可以返回具有范围数组的给定邮政编码的最可能状态。
这不是一个验证器——并不是一个范围中的每个数字都被分配为邮政编码，未来可能会添加新的范围。

我最终从美国邮政编码数据库下载了一个CSV文件。我也不想与依赖项API集成。
CSV文件中包含的信息比我需要的要多。我只为zip列和state列解析了文件，并创建了一个zip代码到state代码的Hash（我使用的是RubyonRails），我在应用程序中维护和使用它。你可以用Javascript做类似的事情。
目前对使用范围的公认答案的修订存在问题。
首先，这个答案没有考虑到像AE（欧洲武装部队）这样的美国边远地区https://www.zip-codes.com/state/ae.asp)，AA（美洲武装部队https://www.zip-codes.com/state/aa.asp)，以及其他。
其次，范围会发生变化，邮政编码也会发生变化（尽管很少）。已接受的答案有几个修订，以添加"；边缘情况"；以及"；角落案例"；到多年来的范围。但我认为这里真正发生的是邮政编码在变化，答案中的范围必须不断更新。我发现了几个不适用于当前已接受答案修订版的邮政编码。可能还有更多的例子——我没有做详尽的检查。【Fiddle】
// Prints DC, but should be MD
// https://www.zip-codes.com/zip-code/20588/zip-code-20588.asp
console.log(`20588: ${getState("20588")}`);
// Prints OK, but should be TX
// https://www.zip-codes.com/zip-code/73960/zip-code-73960.asp
console.log(`73960: ${getState("73960")}`);
// Prints ID, but should be WY
// https://www.zip-codes.com/zip-code/83414/zip-code-83414.asp
console.log(`83414: ${getState("83414")}`);
// Prints OK, but should be TX
// https://www.zip-codes.com/zip-code/73960/zip-code-73960.asp
console.log(`73960: ${getState("73960")}`);
的确，从美国邮政编码数据库的CSV文件下载只代表邮政编码数据的一个时间点。任何使用此解决方案的人都需要定期重新下载该文件，以获得最新的数据。但考虑到他们网站上的保证，与其依赖范围，不如依赖这个保持不变的真相来源。
来自他们的网站：
"；我们不断监控USPS数据的重大变化，并在发生重大变化时发布新数据。我们的信心非常高，因此我们提供退款保证：如果您在我们更新数据之前发现任何重大更改，我们将全额退款"
我意识到OP最初要求PHP或JS，但我最终来到了这里，所以其他人可能也会觉得这很有用。
这是一个带有更新邮政编码范围的C#版本（根据42k邮政编码的数据库构建）

在使用所提供答案的未修改版本之前，请确保考虑您的特定需求。
例如，如果您需要"；扩展的"；例如以下位置，您可能需要调整提供的代码以包括以下区域：
- 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)
以下是一些（粗略的）调整，可以添加到目前接受的Tony Brasunas的答案中：
} 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
}
