What is a virtual number for WhatsApp?

A virtual WhatsApp number is a phone number that lives in the cloud instead of on a SIM in your pocket. Marketing and operations teams use it to send business WhatsApp messages at volume without tying the campaign to a staff handset.

Bulk23 is a credit-based bulk sender on rotating virtual numbers. You buy credits, paste opted-in contacts, and launch from the dashboard. One credit is one message. The public rate starts at 10,000 credits = $100 USD.

Why personal SIMs fail at marketing volume

WhatsApp is built for people, not for blasting a catalogue to fifty thousand chats from one phone. When a personal number is the firehose, quality drops, sessions die, and the SIM that also holds your family chat is the one that gets restricted. A virtual number keeps that blast off your personal device.

What the virtual number actually does

Role in WhatsApp marketing

Used correctly, a virtual number is the pipe for opted-in broadcasts: promos to people who asked, order updates, restock pings, event reminders. It is not a licence to scrape the web and cold-message strangers. Bulk23 closes accounts that spam.

Typical flow: register → buy credits (auto-credit after pay) → paste numbers with country code → write the message (text, media, CTA) → launch. Destination country on the calculator is for planning the list. The USD rate is the same everywhere.

Lawful use only. You must have valid opt-in. Follow WhatsApp, Meta, GDPR, TCPA and local anti-spam law. Bulk23 is not affiliated with Meta or WhatsApp.

How this is different from the official WhatsApp Business API

The official Cloud API is a Meta product with templates, quality ratings and a BSP. Bulk23 is a credit panel on virtual numbers for teams that want a simple buy-and-send workflow. Pick the tool that matches your compliance model. Do not present unofficial sending as the official API.
