WhatsApp Introduces Usernames: A Major Privacy Win for Businesses and Professionals

CHANDIGARH, June 30, 2026 — In a major privacy update, WhatsApp is officially changing how its messaging system works by introducing unique usernames.

For the last decade, you had to share your private mobile phone number to message someone on WhatsApp. This new update changes that by letting you use a custom alphanumeric username instead. This shift helps protect personal data and stops unwanted spam, marketing calls, and online tracking.

Why WhatsApp is Moving Away From Phone Numbers

For over fifteen years, WhatsApp relied entirely on mobile phone numbers to connect users. While this made it easy to find friends, it created big privacy risks as the app grew into a major platform for business.

Sharing your mobile number in open public forums or business directories often exposes you to scraper bots, telemarketers, and hackers. By adding a username layer, WhatsApp allows users to stay visible in public directories without revealing their underlying phone number. This keeps your phone number safe, which is important since it is often linked to your bank accounts and personal records.

Core Features of the New WhatsApp Username System

The new system goes beyond simply adding a text handle to your page. It includes several security and discovery features to keep you safe:

• Hidden Phone Numbers: When you use a username, it becomes your main identity. If a new contact searches for your handle and messages you, your phone number stays completely hidden. Only people who already have your number saved in their phone book can see it.

• PIN-Protected Discovery: To prevent bots and strangers from guessing your username and messaging you, WhatsApp has added an optional 4-digit Secret PIN layer. If you turn this on, someone who knows your username still cannot chat with you unless they enter your custom PIN.

• Custom Alphanumeric Handles: Every username must be completely unique. Your handle must be at least 5 characters long and can include lowercase letters, numbers, periods, and underscores.

Key Benefits for Businesses and Regular Users

This technical update brings real advantages for professionals, business owners, and everyday consumers:

• For Business Owners: If you manage an enterprise or a small business, you no longer need to buy extra SIM cards or give out your personal mobile number to clients. Displaying a clear username like @YourBrand on your website or business card gives clients a professional way to contact you while keeping your private life separate.

• For Bloggers and Commentators: Writers and analysts often interact with large, unverified online groups to gather stories or run polls. Using a public handle protects your identity. It stops bad actors from using your phone number to track your location or run background checks on you.

• For Everyday Security: For the average user, this makes daily chores safer. Whether you are joining a neighborhood group, messaging a delivery driver, or buying items on an online marketplace, you can coordinate easily with strangers without leaving a permanent digital footprint linked to your SIM card.

Step-by-Step Guide: How to Set Up Your WhatsApp Username

Because this update is rolling out in phases, make sure you update your app to the latest version through the Google Play Store or Apple App Store first.

Follow these steps to claim your handle:

1. Open WhatsApp on your mobile phone.

2. Tap the Three Dots in the top right corner (on Android) or select the Settings Gear (on iOS).

3. Tap on your Profile Picture at the top to open your Profile Settings page.

4. Look for the new field labeled "Username" right below your Name and About sections.

5. Tap the Pencil or Edit icon next to it.

6. Type in your desired handle. If the name is available, you will see a green checkmark.

7. Tap Save or Done.

How to Turn on the Inbound PIN Layer

1. Once your username is saved, go to the Username Settings sub-menu.

2. Turn the toggle for "Require PIN for New Chats" to ON.

3. Choose a memorable 4-digit PIN sequence and save it.

Managing Your New Custom Quick Links

Once your handle is active, WhatsApp automatically creates a short web link for your profile: wa.me/yourusername.

You can paste this link directly into your website footer, email signatures, or social media pages. When a user clicks it, it opens a secure chat window with you inside their WhatsApp app without ever showing them your digits.

Because usernames must be entirely unique across the world, the best business names and short handles are being claimed quickly. Registering your handle early stops competitors or copycats from taking your name later on.
