Want to know how to send a WhatsApp message without saving the number? You can open a chat using a WhatsApp link, without adding another person to your contacts. It is useful when you need to ask a seller a question, contact a delivery partner or follow up on a one-time enquiry.
You only need the correct number and country code to get started. Below, we’ll show you the steps for your phone and computer, explain how AiSensy’s free tool helps you create the link, and cover common problems.
How to Send a WhatsApp Message Without Saving the Number
Use WhatsApp’s click-to-chat link. Open https://wa.me/<number> in a browser, replacing the placeholder with the recipient’s full international number. Continue to WhatsApp, write your message and tap Send. The recipient must have an active WhatsApp account. This is an official WhatsApp feature.
Step 1: Check the number and country code
For an Indian mobile number, use 91 followed by the 10-digit number. Include digits only, without a plus sign, spaces, brackets or hyphens. Keep any zeros that are part of the actual number.
Copy the number from the information the person gave you. If you found a business through an advertisement, compare its contact details with its official website before sharing order or account information.
Step 2: Open the link in your browser
Type the link into Chrome, Safari or your preferred browser’s address bar. For India, the format looks like this:
https://wa.me/91XXXXXXXXXXReplace all ten Xs with the actual mobile number. This is a masked example, not a working contact link. For another country, use that country’s dialling code and the correctly formatted number.
Step 3: Start the conversation
Choose the option to continue to WhatsApp. Check that you have opened the intended chat, then type your message and send it. Opening the link alone does not send anything.
A useful first message gives the recipient some context. Instead of sending only “Hi”, explain who you are and what you need. For example: “Hi, I’m asking about the desk listed on your website. Is the oak finish available?”
How to Use This Method on Android and iPhone
The same link format works on both phones. Use the browser you normally open links with, then follow its prompt to continue in WhatsApp.
On Android: open Chrome or another browser, enter your completed link and continue to WhatsApp. If your phone asks which app should open it, choose the WhatsApp account you intend to use.
On iPhone: open Safari or another browser, enter the link and accept the prompt to open WhatsApp. Review the conversation before sharing your message, photo or document.
You might also see an option to search for an unsaved number from WhatsApp’s new-chat screen. The interface can differ between app versions. If the search does not offer a chat, use the browser-link method above.
Create a WhatsApp Link with AiSensy’s Free Link Generator
Prefer a form instead of building the URL yourself? Use AiSensy’s free WhatsApp Link Generator. It lets you choose a country, enter a number and add a message. The tool also shows a message preview.
Step 1: Enter the WhatsApp number
Open the generator and select the country. Enter the number in the phone-number field, without repeating the country code already selected beside it.
Step 2: Add an optional message
Use the Custom Message field to write an opening line. For a business link, write from the customer’s perspective, such as “Hi, I’d like to know more about your services.”
Step 3: Generate and check your link
Click Generate Link. Open the result to check the destination and message before sharing it. The tool also provides a QR code. Our WhatsApp link guide covers more ways to use the finished link.
Which number should you enter? Enter the recipient’s number if you want to contact them. Enter your own business number if you want customers to contact your business. This small distinction prevents a common mistake: generating a link that opens a chat with the wrong person.
How to Message an Unsaved Number on WhatsApp Web
Working on a laptop? Click-to-chat also supports WhatsApp Web. Open the completed link in your desktop browser and choose the web option if the landing page offers one. Sign in or link your device if prompted.
If you need help connecting your account, follow our WhatsApp login guide. Once the chat opens, check the recipient, write your message and send it.
This is convenient when the conversation involves a file already on your computer. For example, you can ask a supplier about a product and attach your requirements from the same device. Review the attachment before sending so it includes only what that person needs.
Other Ways to Chat Without Saving a Contact
Message from a shared contact card
If someone has shared a contact card in a chat, you can message that person directly from the card. You do not have to add them to your address book first. WhatsApp confirms this in its contact-sharing instructions.
This suits a referral. A colleague can share a supplier’s contact, and you can introduce yourself with the reason for getting in touch. Ask for the appropriate business contact rather than circulating someone’s personal details unnecessarily.
Use a username where the feature is available
WhatsApp’s username guidance explains that you can start a chat using a person’s exact username. You may also need their username key if they have set one. The feature is rolling out gradually, so availability can vary.
If someone gives you a username, use it as provided. If your app does not offer that option yet, ask for their WhatsApp contact link instead.
What Should You Write in the First Message?
A person who has not saved your number needs a reason to recognise your enquiry. Start with your name or reference, explain the purpose and ask one clear question. Keep extra details for the reply.
Ask a seller about a product
Hi, I’m [Name]. I saw [product name/code] on your website.
Could you confirm whether [size/colour] is available?
Contact a delivery partner
Hi, I’m [Name], the recipient for order [reference].
Could you confirm the delivery time window?
Request information from a service provider
Hi, I’m [Name]. I’d like to ask about [service].
Do you cover [area], and what details do you need for a quote?
These are examples for individual conversations. Replace the bracketed details before sending. Do not paste order references, addresses or personal documents into a public link that anyone can access.
Why Is Your WhatsApp Link Not Working?
Start with the number, then check how the browser opens the link. The following checks help you narrow down the problem without installing another messaging tool.
| What you see | What to check |
|---|---|
| Invalid number | Recheck the country code and each digit. Ask the recipient to confirm the number they use on WhatsApp. |
| Link opens a search result | Paste the complete URL into the browser address bar. Include https:// at the beginning. |
| Chat does not open in the expected app | Check the browser’s open-in-app prompt. If you use more than one WhatsApp account, check which one is opening. |
| WhatsApp Web asks you to sign in | Complete the normal account-linking process, then open the link again. |
| Link works, but the preview is missing | Try opening the link itself. A missing preview is not proof that the destination is broken. |
If the chat opens but a message does not reach the recipient, that is a different issue from link formatting. See our guide to WhatsApp messages not being delivered before repeatedly resending the same message.
How Businesses Can Make It Easier for Customers to Start a Chat
A customer should not need to copy your number, save a contact and search for your business just to ask a question. Place a direct contact link beside the information that prompts the enquiry.
On a product page: add a link labelled “Ask about this product”. Suggest a short opening message that includes the product name or code, so your team knows where to begin.
On social media: use the link where customers look for contact details. Our guide to adding a WhatsApp link to your Instagram bio explains one practical placement.
In a shop or on packaging: use a WhatsApp QR code with a clear purpose, such as asking about product care. Test the printed version from a customer’s phone before producing a large batch.
When several people handle enquiries, a shared WhatsApp inbox helps your team manage the conversations. AiSensy brings customer chats and contact context into one workspace, so the next reply can build on the customer’s question.
There is a difference between making contact easy and starting a promotional campaign. Businesses must obtain the required opt-in and respect opt-outs. The Business Platform also requires approved templates for business-initiated conversations and messages outside the 24-hour customer service window. See WhatsApp’s Business Messaging Policy.
For a single personal chat, you do not need to set up an API account. Consider AiSensy when you need a team workflow, campaign tools or supported automation. Review current plans and add-ons against the features your business actually needs.
Frequently Asked Questions
Q. Can I send a WhatsApp message without adding a contact?
Yes. Use a click-to-chat link with the recipient’s full international number, or message them from a shared contact card. You can start the conversation without creating a phone contact.
Q. Do I need another app to message an unsaved number?
No extra app is needed for the browser-link method. Use your browser and WhatsApp, or continue through WhatsApp Web on a computer. A link generator is optional.
Q. Is it free to message an unsaved number on WhatsApp?
You do not pay a separate fee just because a number is unsaved. Your usual internet or mobile-data costs apply. WhatsApp Business Platform messaging and provider subscriptions have separate pricing.
Q. Can I include an opening message in my WhatsApp link?
Yes. Add a custom message through AiSensy’s Link Generator and check the preview. The text appears for the sender to review; it is not automatically sent on their behalf.
Q. Does a WhatsApp link save the recipient to my phone?
A click-to-chat link opens a conversation. It does not require you to create a phone contact. If you later want to save the person, use the contact options in the chat.
Q. Does messaging an unsaved number make me anonymous?
No. Not saving a contact is different from hiding your identity. Do not assume the recipient cannot identify you. Review your privacy settings before starting conversations with people you do not know.
Q. Can I send a document after opening the chat?
You can use the attachment options available in that conversation. Check the recipient before sharing a document, and remove information that is not relevant to the enquiry.
Q. Can businesses send bulk messages using a wa.me link?
A wa.me link is a way to open an individual chat, not a campaign-sending tool. Businesses that need campaigns should use an appropriate Business Platform workflow with permission, approved templates where required and opt-out handling.
