The WhatsApp group number extractor extension is a browser extension that allows users to easily extract phone numbers from WhatsApp group invite links. This extension works by parsing the invite link and extracting just the relevant phone numbers, making it easy to quickly get the group admin’s number or numbers of other group participants.
How does the WhatsApp group number extractor work?
The WhatsApp group number extractor browser extension works through the following steps:
- It detects when a WhatsApp group invite link is opened in the browser
- It extracts the encoded phone numbers from the invite link
- It decodes the phone numbers into a human readable format
- It displays the extracted phone numbers in an overlay or popup
Here is a more detailed explanation of how it works:
- The extension has access to the pages you visit in the browser and can read the page content.
- When you open a WhatsApp group invite link, the extension scans the page to extract the invite URL.
- It checks if the URL matches the pattern used by WhatsApp invite links.
- If it matches, the extension extracts the encoded phone number segment from the URL.
- This encoded string represents one or more phone numbers concatenated together.
- The extension then decodes this string to split it into individual phone numbers.
- Finally, it displays these extracted phone numbers in an overlay window or popup.
So in summary, the extension leverages its access to browser page content to read WhatsApp invite links, extract the relevant data, decode it and display the hidden phone numbers.
What are the benefits of using this extension?
Here are some of the key benefits of using the WhatsApp group number extractor browser extension:
- Quickly get group admin numbers – No need to save invite links and extract numbers manually. The extension does this automatically.
- Avoid joining unwanted groups – You can check the admin number before joining a random group.
- Easily get member numbers – Member numbers are also extracted when available in the invite link.
- No app installation needed – It works through the browser so no app install required.

Overall, it makes extracting numbers from WhatsApp group invites super easy and fast instead of having to manually copy links and extract numbers yourself.
What browser extensions provide this capability?
Here are some of the most popular browser extensions that offer WhatsApp group number extraction functionality:
| Extension Name | Works On |
|---|---|
| WA Web Plus | Chrome, Edge, Brave, Firefox |
| WebWA | Chrome |
| WhatsApp Web Extractor | Chrome |

These extensions can be installed from the Chrome Web Store or the Firefox Add-Ons site. Once installed and enabled, they will automatically extract numbers from WhatsApp group invite links opened in the browser.
Are there any apps that can do this?
In addition to browser extensions, there are also a couple of apps available that can extract numbers from WhatsApp group invites:
- WAExtractor – Android app that extracts numbers from invite links
- GetAdmin – Android app to get admin numbers from invites
However, the functionality is essentially the same as the browser extensions – parse the invite link, extract encoded numbers, decode them and display. The main difference is just that these are standalone mobile apps instead of browser add-ons.

Using the WhatsApp number extractor browser extension is very simple. Just follow these steps:
- Install the extension from the Chrome Web Store or Add-ons store.
- Once installed, pin the extension for easy access.
- When you come across a WhatsApp group invite link, open it.
- The extension will automatically scan the link and extract numbers.

The extension will run automatically in the background whenever you open WhatsApp group invite links. Some extensions also have options to disable number extraction if required.
Use cases and examples
Here are some examples of how the WhatsApp group number extractor extension can be useful:
- Getting admin number from public groups – If you get an invite to join a random public group, you can check the admin number before joining to see if it is legit.
- Checking member numbers – For closed groups, you can get the numbers of various members from the invite link and then save them.
- Making groups discoverable – Group admins can share invite links on websites to make their groups public while still obscuring numbers. Users can easily extract the number from such links to join.
- Analyzing groups – Researchers can extract numbers from thousands of public group invites to analyze WhatsApp group statistics and trends.
- Reporting spam – You can extract the admin number from a spam / offensive group and report it to WhatsApp.
The ability to easily extract numbers from group invite links unlocks various use cases like these.
Limitations of this technique
While the WhatsApp group number extractor makes it easy to get numbers from invites, there are some limitations to be aware of:
- It only works for public invite links, not for private groups.
- Cannot extract numbers if group has enabled restrict invites setting.
- May not work reliably on some poorly formatted invite links.
- Does not bypass any encryption, only extracts what is already visible.
- Requires users to voluntarily open the public invite link.
- Does not extract names or any other info, only phone numbers.
So it does not reveal any private or hidden information and has some reliability challenges. Admins can still restrict their groups or encrypt the links for privacy.
Is it legal to extract WhatsApp numbers this way?
The legality of extracting numbers from WhatsApp group invites depends on how it is being done and the specific country’s laws. Here are some key factors to consider:
- If the group has open invite links shared publicly, it is generally legal to extract.
- If done manually by copying invite links, it is legal in most countries.
- Automated extraction through extensions may be legally ambiguous in some regions like the EU.
- Consent of the numbers’ owners often determines legality according to privacy laws.
- There are few definitive laws explicitly allowing or prohibiting this practice.
- WhatsApp’s Terms of Service prohibit scraping/extracting user data from their service.
So in summary – for public links it is likely okay, private groups without consent may be illegal, and automation makes it ethically questionable. Users should carefully check laws for their country before extracting numbers.
Conclusion
The WhatsApp group number extractor browser extensions and apps make extracting phone numbers from public group invite links quick and easy. While it can be useful in many scenarios, users should be careful to not misuse this capability and be aware of potential legal issues. Group admins can also enhance privacy by restricting invites or using non-guessable invite links. Ultimately, it provides convenience but should be used ethically and legally.
