匹配 E.164 格式电话号码的正则表达式 [英] Regular expression matching E.164 formatted phone numbers

问题描述

我需要添加一个匹配所有可能的有效 E.164 格式电话号码的正则表达式.

I need to add a regular expression that matches all possible valid E.164 formatted phone numbers.

这个正则表达式适用于北美电话号码，但我需要一些也适用于国际号码的东西:

This regex works fine for for North American phone numbers, but I need something that will work for international numbers as well:

^(+1|1)?([2-9]\d\d[2-9]\d{6})$

^(+1|1)?([2-9]\d\d[2-9]\d{6})$

例如:[phone] 匹配13172222222 仍然匹配，因为 +1 或 1 是可选的3172222222 仍然匹配，因为 +1 或 1 是可选的3171222222 不匹配并且不是有效的 NANPA 编号.

Example: [phone] matches 13172222222 still matches because +1 or 1 are optional 3172222222 still matches because +1 or 1 are optional 3171222222 does not match and is not a valid NANPA number.

我也遇到了这个相关问题，但我认为这对我的需求来说太疯狂了.就我而言，我只是验证黑名单的条目，并将其与传入的 Twilio 数据进行比较；所以，我不太关心国家代码有效的天气.我真的只需要测试一个数字是否与一般的 E.164 形式相匹配，而不是假设它是 NANPA.

I also came across this related question, but I think that it is way too crazy for my needs. In my case, I am simply validating an entry for a blacklist, which I'm comparing to incoming Twilio data; so, I care much less about weather a country code is valid. I really only need to test if a number matches the general E.164 form, rather than assuming it's a NANPA.

为了更好地理解我需要匹配的内容，这里是 Twilio 文档:

To be better understand what I need to match, here is an example from the Twilio Documentation:

请求中的所有电话号码来自Twilio 采用 E.164 格式，如果可能的.例如，[phone]将通过'[phone]'.不过偶尔也会有这样的情况Twilio 无法标准化的地方来电显示到 E.164.在这些情况 Twilio 将报告原始数据来电显示字符串.

All phone numbers in requests from Twilio are in E.164 format if possible. For example, [phone] would come through as '[phone]'. However, there are occasionally cases where Twilio cannot normalize an incoming caller ID to E.164. In these situations Twilio will report the raw caller ID string.

我想匹配 [phone] 之类的东西，但不是 [phone]、415555434、555-4345 或 5554345.不过，正则表达式不应限制自己只匹配美国国家/地区代码.基本上，它应该匹配 +xxxxxxxxxxx 格式.我还认为这个数字可能更长，因为有多位国家代码，例如在英国.T-Mobile 的英国号码是 [phone]，如果我能想出更好的例子，我会更新这个.

I want to match something like [phone], but not [phone], 415555434, 555-4345 or 5554345. The regex should not restrict itself to only matching the US country code though. Basically, it should match the +xxxxxxxxxxx format. I also think the number could be longer, as there are multi-digit country codes, such as in the UK. T-Mobile's UK number is [phone] I'll update this if I can come up with a better example.

推荐答案

接受的答案是好的，除了 E.164 号码最多可以有 15 位数字.规范也没有指出最小值，所以我不一定指望 10.

The accepted answer is good, except an E.164 number can have up to 15 digits. The specification also doesn't indicate a minimum, so I wouldn't necessarily count on 10.

应该是^\+?[1-9]\d{1,14}$
