Frequently Asked Questions

▶Is this different from WhatsApp Business?

NumSwift solves a specific friction point: messaging someone without saving them first. WhatsApp Business is a full messaging platform with catalogs and automated replies. You can use NumSwift alongside WhatsApp Business — it opens chats in whichever WhatsApp app you have installed.

▶Can I use this for both customer and vendor communication?

Yes. NumSwift does not distinguish between customer or vendor numbers. Any phone number you paste will be formatted and ready to message. This makes it useful for the full range of small business communications.

▶Do I need to install anything?

No. NumSwift runs entirely in your web browser. Open the site, paste a number, and tap WhatsApp. It works on phones, tablets, and desktops. You just need WhatsApp installed on the device where you want to send the message.

▶How does it handle numbers from different countries?

Select the country from the dropdown or let NumSwift detect it from the number's prefix. This is especially helpful if you work with international suppliers or serve customers from different countries visiting your area.
