How to send a WhatsApp message to an unsaved number
Adding every new lead to your contact list is messy and slow. Whether you're following up a job applicant, replying to an Instagram DM lead, or pinging a one-time customer, you can start a WhatsApp chat without saving the number — using methods officially supported by Meta.
Here are five reliable techniques covering Android, iPhone and the WhatsApp Business API.
- 1
Method 1: wa.me link
Open https://wa.me/<countrycode><number> in any browser. WhatsApp opens directly to that chat.
- 2
Method 2: dialer shortcut (Android)
Open the phone dialer, type the number with country code, then long-press the share menu and pick 'WhatsApp'. Saves a tap.

Method 3: Siri or Google Assistant
Say 'Hey Siri, WhatsApp +91 99999 99999, say hi'. The assistant opens WhatsApp to a new chat with that number.

Method 4: WhatsApp Web
On desktop wa.me works the same — perfect for support teams handling many leads.
- 5
Method 5: Bulk via the API
In a BSP dashboard, paste any number and send an approved template — no saving, no manual chat opening, full audit log.
Pro tips
- → Always use full international format with country code, no '+' in the wa.me URL.
- → Bookmark wa.me/91XXXXXXXXXX for your own business number — fastest way to onboard customers.
- → For sales teams, the API method is the only one that scales without burning out reps.
Frequently asked questions
Will the unsaved contact see my profile?
Yes — they see your WhatsApp display name and profile picture, even unsaved.
Why does WhatsApp Web say 'invalid phone number'?
You used + or special chars. Use only digits and country code.
Is this method against WhatsApp policy?
No — wa.me is official. Modified WhatsApp apps that automate bulk unsaved sends ARE against policy.
