A private number is when a caller intentionally blocks their number from showing on caller ID. They're used to hide the identity of callers, and they can appear on your phone as ‘Private Caller’, ‘Restricted’, ‘Blocked’, 'No Caller ID', or other similar variations.
How does using a private number affect your business?
Customers will feel wary when called by unknown numbers. Although calling from a mobile number or standard area code may look unprofessional compared to Freephone numbers like 0800 business numbers, it may still be better than using a 'No Caller ID' number.
These private numbers can also be associated with scammers and bad business, and could affect your business negatively by damaging brand image and giving you a higher volume of call rejections.
There are some reasons to use private numbers for your business. For example, they can be helpful if you use your personal mobile and you don't want people contacting you out of hours, or if you run a customer service line and don't want people ringing back and engaging the line. However, even in these cases, you should be prepared for a higher rejection rate for your calls.

Private number FAQs
How do you block private numbers?
On most phones, you can find an option in settings (under call rejection or call options) that allows you to block private numbers. Look for the 'auto reject list' in your settings - from there you should be able to block any unknown numbers.
How do you call through a private number?
To block an individual call in the UK, dial the prefix 141 (in the USA, the prefix is 67) before the recipient's number and then ring as normal. This will hide your number from the recipient, so that it shows up as something like 'No Caller ID' on their phone. Bear in mind, though, that this will only hide your number for this one particular call'; you'll need to repeat the same process each time you want to block your number.
How do you hide calls from a mobile?
On most mobile phones, you'll be able to change the settings so that your number is hidden each time you make a call. While the process is likely to vary from phone to phone, many will have an option like 'hide my number', 'restrict my identity' or something similar. On lots of smartphones, you can choose to save your settings to make your number private on all calls going forward; change your settings as and when it's appropriate.
Are there more ways to block your number?
You may also be able to contact your mobile provider and ask them to adjust your preferences.

Great to speak to a UK based call centre on the phone, Dan couldn't have been more helpful and friendly! Everything was explained clearly, and the switch over to Virtual Landline from my old copper landline went really smoothly. It did exactly what it promised. Really happy with how easy it all was.
