Why You Should Keep Your Mobile Number Private and Use a Landline for WhatsApp Business

[Twiggy]

Many small business owners (especially service providers) use their mobile number for everything — calls, appointments, WhatsApp orders, enquiries, etc. It works fine at first, but there’s a big downside: your mobile becomes your business hotline, and suddenly you’re “on call” 24/7.

If you’ve ever had late-night messages, people calling at odd hours, or your personal number being shared around without asking, you’ll know exactly what I mean.

A simple fix that more business owners should consider is:

Keep your mobile number for yourself, and use a landline for WhatsApp Business.

Here’s why it helps and how to set it up.

Why Separate Your Personal Mobile and Business WhatsApp?

Using a landline for WhatsApp Business allows you to:

✔ Keep your personal mobile number private and use what's app for your friends.
✔ Avoid late-night calls/messages on your personal phone
✔ Present a more “established business” contact number
✔ Keep boundaries between personal and business time
✔ Allow customers to message your business number on WhatsApp
✔ Still manage everything from your mobile device

A lot of customers now prefer messaging over calling, but you shouldn’t have to sacrifice your personal life just to make that convenient.

With WhatsApp Business, your landline becomes your public number, while your mobile stays your private one.

 Using a Landline with WhatsApp Business: Yes, It Works !!! be patient!!!!

WhatsApp Business does support landline numbers, but there’s one key detail that catches people out:

Landlines can’t receive SMS verification codes.

So during setup, WhatsApp will send an SMS first (which will obviously fail), and only then will it offer the voice call verification.

📌Setup Instructions (Important Steps)

1. Install WhatsApp Business (blue icon) on your phone.

2. Enter your landline number in international format (e.g. +44 1473…).

3. It will attempt an SMS verification first.

4. Wait for it to time out — don’t cancel it ----wait keep the app open!!!!!!!!!!!!!!!!!!

5. After ~60 seconds, tap:

   “Didn’t receive a verification code?”

   You will probably get wait one hour !  then if so wait an hour but you should see "did not get a verification code ! Click that and you will get the option to request a voice call.  select that !

6. Now choose “Call me”.

7. WhatsApp will call your landline with a 6-digit code.

8. Enter the code into the app — done.

Your WhatsApp Business account is now tied to your landline, but you still manage it from your mobile.

⏱️ If You See “Wait 1 Hour”

If you retry verification too quickly, WhatsApp rate-limits you and shows:

“Try again in 1 hour”

This isn’t a landline issue and doesn’t mean it won’t work — it just means you need to wait for the timer before trying again. After that, follow the steps above without rushing.

✨The End Result

Once it’s set up:

✔ Your business WhatsApp is linked to your landline
✔ Customers message that number via WhatsApp
✔ You reply from the WhatsApp Business app on your phone
✔ Your mobile number stays private
✔ You control when you’re available

It’s a small change with a big impact on work/life balance — especially for sole traders, florists, beauty professionals, trades, therapists, and anyone who doesn’t want to be “always on”.

Good luck trying this - If you have a system in place as we do - where the landline diverts to mobile - turn the divert off  as you will have to press key pad #9 have a paper and pencil ready. then hey presto you mobile number is yours again!  

Also Great if you use the "chaty" add on for your square online site. https://chaty.app/

Thanks for sharing. I am a freelancer and this guide has helped me a lot.

We don't have landlines in Australia any more. It's all VoIP, but I guess you can still get a number. 
But I refuse to use WhatsApp - I installed it once and kept getting all sorts of spammy messages on it so I cancelled it and deleted it and will never use it again. 

Most of my customers message me on Facebook which works well for me. Some use my mobile. I don't care, if I don't want to answer it I just let it go to voicemail. 

But as for keeping things private - I run from home and because I allow local pick up SQUARE forces me to put my private address on my website!!! Things don't work if I change it. I would much prefer to just have it like I did for about 3 years without issue and just have my town listed and I can contact people with the address after they place an order.  This is far more important to me than having my phone number available.

Another alternative is Google Voice. I use the free version. It isn't intended for business use, but I've been using it as a business line for a few years. It will ring on more than one device if you want it to; it attaches to your mobile number, but that's not the number you give to others. If you have the money to spare, the business version of Google Voice offers several features, including the ability to ring a desktop phone.

We actually got a 2nd mobile phone because of this!
