【问题标题】：Create phone number regex [duplicate]创建电话号码正则表达式 [重复]
【发布时间】：2016-05-02 21:10:57
【问题描述】：

我正在使用 "^[(\+[0-9]{1,3}\.[0-9]{4,14}(?:x.+)?]$" 正则表达式来验证电话号码. 我希望它也适用于国际号码。它适用于以下模式： +4454475294x364

我还想添加空格和“-”。例如：+44 544-75294 x364。

我需要在我的正则表达式中进行哪些更改。

谢谢。

【问题讨论】：

您必须区分北美和世界其他地区的手机验证。根据历史原因，电话号码不同。

【解决方案1】：

说明

您提供了以下您希望匹配的数字示例。

+4454475294x364
+44 544-75294 x364
(123) 555-1212x4567
123-555-1232

正则表达式

此正则表达式将执行以下操作：

匹配您提供格式的国际号码
匹配北美号码
如果电话号码后跟分机号，则捕获该分机号
在明显位置允许使用空格、连字符和括号
这仅限于您在问题中列出的格式

^(?:[+][0-9]{2}\s?[0-9]{3}[-]?[0-9]{3,}|(?:[(][0-9]{3}[)]|[0-9]{3})\s*[-]?\s*[0-9]{3}[-][0-9]{4})(?:\s*x\s*[0-9]+)?

注意：对于 Java，您需要转义正斜杠 \ 以使其看起来像 \\。
