Regular Expressions to Match Social Media Profiles

This repository lists regular expressions to match and extract information from URLs of social media profiles. So if you find a hyperlink to this repo somewhere on the web, i.e. https://github.com/lorey/social-media-profiles-regexs/, the regular expressions in this repo allow you find out it's a Github link pointing to a repo as well as extract the username lorey and the repo name social-media-profiles-regexs from this URL.

Features:

  • detect the platform a url points to (all major platforms supported)
  • extract the information contained within the url (without opening the url, of course)
  • extract emails and phone numbers from hyperlinks

Please note: If you want to extract social media links, depending on your case, there are possibly easier ways:

  • I've created a Python library called socials that uses these expressions to automate url detection and data extraction. You input the urls, it extracts the type of platform as well as the contained information, e.g. the linked social media profiles.
  • There's also a Socials API which makes the socials python package available via REST and JSON. You can use it for free at socials.karllorey.com or deploy it yourself. You simply input any URL you want to extract profiles from. It will then fetch and return all social media links from the given website. Try it here.

If you're missing a particular platform, please feel free to add it. Also feel free to add a test that does not work. An explanation of how this repo works can be found in CONTRIBUTING.md. You might also open an issue, of course, I'm happy to help!

Table of Contents

angellist

company

(?:https?:)?\/\/angel\.co\/company\/(?P<company>[A-z0-9_-]+)(?:\/(?P<company_subpage>[A-z0-9-]+))?

Examples:

job

(?:https?:)?\/\/angel\.co\/company\/(?P<company>[A-z0-9_-]+)\/jobs\/(?P<job_permalink>(?P<job_id>[0-9]+)-(?P<job_slug>[A-z0-9-]+))

Examples:

user

(?:https?:)?\/\/angel\.co\/(?P<type>u|p)\/(?P<user>[A-z0-9_-]+)

There are root-level direct links to users, e.g. angel.co/karllorey, that get redirected to these new user links now. Sometimes it's /p/, sometimes it's /u/, haven't figured out why that is...

Examples:

crunchbase

company

(?:https?:)?\/\/crunchbase\.com\/organization\/(?P<organization>[A-z0-9_-]+)

Examples:

person

(?:https?:)?\/\/crunchbase\.com\/person\/(?P<person>[A-z0-9_-]+)

Examples:

email

mailto

mailto:(?P<email>[A-z0-9_.+-]+@[A-z0-9_.-]+\.[A-z]+)

This is for scraping only and in no way usable as a validation.

Examples:

facebook

profile

(?:https?:)?\/\/(?:www\.)?(?:facebook|fb)\.com\/(?P<profile>(?![A-z]+\.php)(?!marketplace|gaming|watch|me|messages|help|search|groups)[A-z0-9_\-\.]+)\/?

A profile can be a page, a user profile, or something else. Since Facebook redirects these URLs to all kinds of objects (user, pages, events, and so on), you have to verify that it's actually a user. See https://developers.facebook.com/docs/graph-api/reference/profile

Examples:

profile by id

(?:https?:)?\/\/(?:www\.)facebook.com/(?:profile.php\?id=)?(?P<id>[0-9]+)

Examples:

github

repo

(?:https?:)?\/\/(?:www\.)?github\.com\/(?P<login>[A-z0-9_-]+)\/(?P<repo>[A-z0-9_-]+)\/?

Exclude subdomains as these redirect to github pages sometimes.

Examples:

user

(?:https?:)?\/\/(?:www\.)?github\.com\/(?P<login>[A-z0-9_-]+)\/?

Exclude subdomains other than www. as these redirect to github pages sometimes.

Examples:

google plus

user id

(?:https?:)?\/\/plus\.google\.com\/(?P<id>[0-9]{21})

Matches profile numbers with exactly 21 digits.

Examples:

username

(?:https?:)?\/\/plus\.google\.com\/\+(?P<username>[A-z0-9+]+)

Matches username.

Examples:

hackernews

item

(?:https?:)?\/\/news\.ycombinator\.com\/item\?id=(?P<item>[0-9]+)

An item can be a post or a direct link to a comment.

Examples:

user

(?:https?:)?\/\/news\.ycombinator\.com\/user\?id=(?P<user>[A-z0-9_-]+)

Examples:

instagram

profile

(?:https?:)?\/\/(?:www\.)?(?:instagram\.com|instagr\.am)\/(?P<username>[A-Za-z0-9_](?:(?:[A-Za-z0-9_]|(?:\.(?!\.))){0,28}(?:[A-Za-z0-9_]))?)

The rules:

  • Matches with one . in them disco.dude but not two .. disco..dude
  • Ending period not matched discodude.
  • Match underscores _disco__dude
  • Max characters of 30 1234567890123456789012345678901234567890

Examples:

linkedin

company

(?:https?:)?\/\/(?:[\w]+\.)?linkedin\.com\/company\/(?P<company_permalink>[A-z0-9-\.]+)\/?

Permalink may be a company id or a regular permalink. The id redirects to the permalink as soon as one is created.

Examples:

post

(?:https?:)?\/\/(?:[\w]+\.)?linkedin\.com\/feed\/update\/urn:li:activity:(?P<activity_id>[0-9]+)\/?

Direct link to a Linkedin post, only contains a post id.

Examples:

profile

(?:https?:)?\/\/(?:[\w]+\.)?linkedin\.com\/in\/(?P<permalink>[\w\-\_À-ÿ%]+)\/?

These are the currently used, most-common urls ending in /in/

Examples:

profile_pub

(?:https?:)?\/\/(?:[\w]+\.)?linkedin\.com\/pub\/(?P<permalink_pub>[A-z0-9_-]+)(?:\/[A-z0-9]+){3}\/?

These are old public urls not used anymore, more info at quora

Examples:

medium

post

(?:https?:)?\/\/medium\.com\/(?:(?:@(?P<username>[A-z0-9]+))|(?P<publication>[a-z-]+))\/(?P<slug>[a-z0-9\-]+)-(?P<post_id>[A-z0-9]+)(?:\?.*)?

Examples:

post of subdomain publication

(?:https?:)?\/\/(?P<publication>(?!www)[a-z-]+)\.medium\.com\/(?P<slug>[a-z0-9\-]+)-(?P<post_id>[A-z0-9]+)(?:\?.*)?

Can't match these with the regular post regex as redefinitions of subgroups are not allowed in pythons regex.

Examples:

user

(?:https?:)?\/\/medium\.com\/@(?P<username>[A-z0-9]+)(?:\?.*)?

Examples:

user by id

(?:https?:)?\/\/medium\.com\/u\/(?P<user_id>[A-z0-9]+)(?:\?.*)

Now redirects to new user profiles. Follow with a head or get request.

Examples:

phone

phone number

(?:tel|phone|mobile):(?P<number>\+?[0-9. -]+)

Should be cleaned afterwards to strip dots, spaces, etc.

Examples:

  • tel:+49 900 123456
  • tel:+49900123456

reddit

user

(?:https?:)?\/\/(?:[a-z]+\.)?reddit\.com\/(?:u(?:ser)?)\/(?P<username>[A-z0-9\-\_]*)\/?

Examples:

skype

profile

(?:(?:callto|skype):)(?P<username>[a-z][a-z0-9\.,\-_]{5,31})(?:\?(?:add|call|chat|sendfile|userinfo))?

Matches Skype's URLs to add contact, call, chat. More info at Skype SDK's docs.

Examples:

  • skype:echo123
  • skype:echo123?call

snapchat

profile

(?:https?:)?\/\/(?:www\.)?snapchat\.com\/add\/(?P<username>[A-z0-9\.\_\-]+)\/?

Examples:

stackexchange

user

(?:https?:)?\/\/(?:www\.)?stackexchange\.com\/users\/(?P<id>[0-9]+)\/(?P<username>[A-z0-9-_.]+)\/?

This is the meta-platform above stackoverflow, etc. Username can be changed at any time, user_id is persistent.

Examples:

stackexchange network

user

(?:https?:)?\/\/(?:(?P<community>[a-z]+(?!www))\.)?stackexchange\.com\/users\/(?P<id>[0-9]+)\/(?P<username>[A-z0-9-_.]+)\/?

While there are some "named" communities in the stackexchange network like stackoverflow, many only exist as subdomains, i.e. gaming.stackexchange.com. Again, username can be changed at any time, user_id is persistent.

Examples:

stackoverflow

question

(?:https?:)?\/\/(?:www\.)?stackoverflow\.com\/questions\/(?P<id>[0-9]+)\/(?P<title>[A-z0-9-_.]+)\/?

Examples:

user

(?:https?:)?\/\/(?:[A-z]+\.)?youtube.com\/user\/(?P<username>[A-z0-9]+)\/?

Examples:

video

(?:https?:)?\/\/(?:(?:www\.)?youtube\.com\/(?:watch\?v=|embed\/)|youtu\.be\/)(?P<id>[A-z0-9\-\_]+)

Matches youtube video links like https://www.youtube.com/watch?v=dQw4w9WgXcQ and shortlinks like https://youtu.be/dQw4w9WgXcQ

Examples:

Monster Regex

If you want to match and extract the data from all urls with one regex, use this monster. It will return the data for all the platforms above. The regex subgroups are prefixed with the platform, e.g. angellist__company instead of just company in the angellist company regex, as some regex implementations don't support defining subgroups more than once which would introduce errors if the same subgroup name is used in two or more platforms.

(?P<angellist__company>(?:https?:)?\/\/angel\.co\/company\/(?P<angellist__company__company>[A-z0-9_-]+)(?:\/(?P<angellist__company__company_subpage>[A-z0-9-]+))?)|(?P<angellist__job>(?:https?:)?\/\/angel\.co\/company\/(?P<angellist__job__company>[A-z0-9_-]+)\/jobs\/(?P<angellist__job__job_permalink>(?P<angellist__job__job_id>[0-9]+)-(?P<angellist__job__job_slug>[A-z0-9-]+)))|(?P<angellist__user>(?:https?:)?\/\/angel\.co\/(?P<angellist__user__type>u|p)\/(?P<angellist__user__user>[A-z0-9_-]+))|(?P<crunchbase__company>(?:https?:)?\/\/crunchbase\.com\/organization\/(?P<crunchbase__company__organization>[A-z0-9_-]+))|(?P<crunchbase__person>(?:https?:)?\/\/crunchbase\.com\/person\/(?P<crunchbase__person__person>[A-z0-9_-]+))|(?P<email__mailto>mailto:(?P<email__mailto__email>[A-z0-9_.+-]+@[A-z0-9_.-]+\.[A-z]+))|(?P<facebook__profile>(?:https?:)?\/\/(?:www\.)?(?:facebook|fb)\.com\/(?P<facebook__profile__profile>(?![A-z]+\.php)(?!marketplace|gaming|watch|me|messages|help|search|groups)[A-z0-9_\-\.]+)\/?)|(?P<facebook__profile_by_id>(?:https?:)?\/\/(?:www\.)facebook.com/(?:profile.php\?id=)?(?P<facebook__profile_by_id__id>[0-9]+))|(?P<github__repo>(?:https?:)?\/\/(?:www\.)?github\.com\/(?P<github__repo__login>[A-z0-9_-]+)\/(?P<github__repo__repo>[A-z0-9_-]+)\/?)|(?P<github__user>(?:https?:)?\/\/(?:www\.)?github\.com\/(?P<github__user__login>[A-z0-9_-]+)\/?)|(?P<google_plus__user_id>(?:https?:)?\/\/plus\.google\.com\/(?P<google_plus__user_id__id>[0-9]{21}))|(?P<google_plus__username>(?:https?:)?\/\/plus\.google\.com\/\+(?P<google_plus__username__username>[A-z0-9+]+))|(?P<hackernews__item>(?:https?:)?\/\/news\.ycombinator\.com\/item\?id=(?P<hackernews__item__item>[0-9]+))|(?P<hackernews__user>(?:https?:)?\/\/news\.ycombinator\.com\/user\?id=(?P<hackernews__user__user>[A-z0-9_-]+))|(?P<instagram__profile>(?:https?:)?\/\/(?:www\.)?(?:instagram\.com|instagr\.am)\/(?P<instagram__profile__username>[A-Za-z0-9_](?:(?:[A-Za-z0-9_]|(?:\.(?!\.))){0,28}(?:[A-Za-z0-9_]))?))|(?P<linkedin__company>(?:https?:)?\/\/(?:[\w]+\.)?linkedin\.com\/company\/(?P<linkedin__company__company_permalink>[A-z0-9-\.]+)\/?)|(?P<linkedin__post>(?:https?:)?\/\/(?:[\w]+\.)?linkedin\.com\/feed\/update\/urn:li:activity:(?P<linkedin__post__activity_id>[0-9]+)\/?)|(?P<linkedin__profile>(?:https?:)?\/\/(?:[\w]+\.)?linkedin\.com\/in\/(?P<linkedin__profile__permalink>[\w\-\_À-ÿ%]+)\/?)|(?P<linkedin__profile_pub>(?:https?:)?\/\/(?:[\w]+\.)?linkedin\.com\/pub\/(?P<linkedin__profile_pub__permalink_pub>[A-z0-9_-]+)(?:\/[A-z0-9]+){3}\/?)|(?P<medium__post>(?:https?:)?\/\/medium\.com\/(?:(?:@(?P<medium__post__username>[A-z0-9]+))|(?P<medium__post__publication>[a-z-]+))\/(?P<medium__post__slug>[a-z0-9\-]+)-(?P<medium__post__post_id>[A-z0-9]+)(?:\?.*)?)|(?P<medium__post_of_subdomain_publication>(?:https?:)?\/\/(?P<medium__post_of_subdomain_publication__publication>(?!www)[a-z-]+)\.medium\.com\/(?P<medium__post_of_subdomain_publication__slug>[a-z0-9\-]+)-(?P<medium__post_of_subdomain_publication__post_id>[A-z0-9]+)(?:\?.*)?)|(?P<medium__user>(?:https?:)?\/\/medium\.com\/@(?P<medium__user__username>[A-z0-9]+)(?:\?.*)?)|(?P<medium__user_by_id>(?:https?:)?\/\/medium\.com\/u\/(?P<medium__user_by_id__user_id>[A-z0-9]+)(?:\?.*))|(?P<phone__phone_number>(?:tel|phone|mobile):(?P<phone__phone_number__number>\+?[0-9.
