Frequently Asked Questions

▶Can I message international hotel guests on WhatsApp?

Yes. NumSwift automatically detects the country code from guest phone numbers, whether they are from the US, Europe, Asia, or anywhere else. This is especially valuable for hotels and tour operators that serve an international clientele.

▶Will the guest see my personal phone number?

The WhatsApp message is sent from whichever WhatsApp account is logged in on your device. Many hotels use a dedicated WhatsApp Business number for guest communication, which is the recommended approach for professional hospitality messaging.

▶Can I extract numbers from my property management system?

Yes. Copy guest contact data from your PMS screen, booking system export, or reservation email, then paste it into NumSwift. The extractor works with text from Opera, Cloudbeds, Little Hotelier, and any other system that displays guest phone numbers.

▶Is this useful for restaurant reservation confirmations?

Absolutely. Copy the customer's booking details from your reservation platform, paste into NumSwift, and tap WhatsApp to send a quick confirmation or reminder. This is faster than typing numbers manually and helps reduce no-shows.
