Until now, WhatsApp has always been closely tied to phone numbers. For businesses, that created a practical but limited logic: the customer talks to a number, clicks a link, scans a QR code, or replies to a campaign. It works, but it's not always elegant, memorable, or ideal from a brand standpoint.

With usernames, WhatsApp starts moving closer to a logic already familiar from social media, domains, and business profiles — WhatsApp is moving past identity by number only, toward identity by name. For businesses that sell, support, and build relationships on WhatsApp, that matters, the same way it already matters to understand WhatsApp username and BSUID in practice.

According to Meta, the idea is to let people and brands be found without necessarily exposing a phone number. It was also noted that there won't be a public username directory — meaning someone needs to know the exact username to start a conversation. That makes brand consistency even more important.

For businesses, the first impact is protection and standardization. If a brand uses one name on Instagram, another on its domain, another on WhatsApp, and another in campaigns, the customer experience gets fragmented. The username can become one more touchpoint that needs to follow the same identity logic.

Picture a brand that already invests in traffic, content, sales, support, and relationship-building. If WhatsApp is a central sales or support channel, the brand's @ inside the app can become an asset similar to a domain or a social profile. It's not just a cosmetic detail. It's recognition, trust, and reduced friction.

There's also a risk to consider. Brands that take too long to organize their presence may find their preferred usernames unavailable or inconsistent with their other channels. Even without a public directory, confusing or misused names can create noise for customers, especially in campaigns and marketing materials.

The most important thing to understand is that a username doesn't replace a service strategy. It's an entry layer. Sales still depend on fast responses, context, well-designed automation, CRM integration, and a good experience. But the front door needs to be clear — and it needs to lead into a trackable, integrated flow, as we cover in how to turn WhatsApp conversations into a sales funnel.

Today, many businesses scatter different contact points: a number on the website, a link on Instagram, a button on an ad, a QR code on printed materials, a rep's personal number, a sales WhatsApp, and a support WhatsApp. That fragmentation makes management and measurement harder. With usernames, a business gets a chance to review how customers actually start a conversation.

That review should include simple questions: what's the official channel? Is the brand name consistent everywhere? Does the customer know they're talking to the right company? Do links, buttons, ads, and printed materials all point to the same flow? Does the conversation land in a trackable operation, or in a loose inbox?

For businesses selling, supporting, or building relationships on WhatsApp, this is a chance to professionalize the identity of the contact point. The username can become part of the communication standard: website, Instagram, campaigns, email signature, proposals, post-sale, and marketing materials — standardizing links, CTAs, QR codes, and campaigns around the same WhatsApp CRM behind them.

The risk is treating this as a minor novelty and putting it off. Digital identity tends to look secondary until it becomes a problem. As a brand grows, standardizing channels, recovering names, and fixing confusion only gets harder.

This is where Merge comes in: if your business sells, supports, or builds relationships on WhatsApp, your brand's @ is starting to matter as much as your domain and your Instagram handle. Not because it solves sales on its own, but because it organizes how customers enter a channel that's becoming more strategic by the day. WhatsApp is moving past being "just a number to call" and getting closer to a relationship environment with identity, metrics, automation, and cost. Usernames are one piece of that shift.

Practical action for businesses

  • Check whether your brand name is available.
  • Aim for consistency with Instagram, Facebook, your domain, and your business name.
  • Standardize links, CTAs, QR codes, and campaign materials.
  • Review how customers currently start a conversation with you.
  • Make sure your official contact leads into a trackable, integrated flow.
