How to Send a WhatsApp Message Without Saving the Number

The two-minute tutorial

1. Identify the country. If the number was written locally you need to know which country it belongs to before anything else.
2. Convert it to international form. Country code, then the local number, digits only. Remove the leading zero if the country uses one.
3. Build the link. https://wa.me/34612345678 — or use the link generator, which formats it for you.
4. Open it. Load the link in Safari and continue into WhatsApp.
5. Verify, then send. Check the number in the conversation header, write your message, send.

Country code formatting

This is the single step where attempts fail. Most countries use a trunk prefix — usually 0 — when the number is written for domestic dialling. That prefix is replaced by the country code, never combined with it.

There are also countries with no trunk prefix at all — Spain, Italy and the United States among them — where the local number is used unchanged after the country code.

Pre-filled messages

Adding ?text= to the link puts your message in the input field before the conversation even opens. Two uses:

• For yourself: your standard opening line is already typed, so a routine message becomes a single tap on send.
• For customers: a link you publish gives them context to start with — "Hi, I'm asking about the blue armchair" — instead of an empty box they never fill.

Spaces, accents and punctuation must be URL-encoded. Generators handle this; typing it by hand does not.

Situations this solves

• One-time conversations. Someone you will speak to once and never again.
• Customers. Order questions, appointment confirmations, quick updates.
• Online sellers. Marketplace buyers who message about an item and vanish if it sells.
• Deliveries. A driver telling a customer they are five minutes away.
• Business inquiries. Leads from a listing, a form or an event badge.
• International numbers. Suppliers and clients abroad whose numbers would otherwise clutter your contacts for years.

Doing it on iPhone

On iPhone the manual route means switching to Safari, typing a URL, and getting the formatting right on a touch keyboard. The Click to Chat app collapses that into one screen: country selector, number field, Open WhatsApp. Repeat messages come from saved templates.
