The service is easy to set-up, and can simply adapt to the system you currently have in place – allowing for the routing of calls to individual departments or people with no extra infrastructure or hardware needed. Your free 0300 number can be set-up and ready to receive calls in minutes.

From the point of view of the person dialling, calls to 0300 numbers cost no more than an equivalent call to an 01 or 02 number, and will legally be included in the minutes allowances of mobile packages. Part of the reason the 0300 range was introduced was in order to eliminate the call confusion costs of 08 numbers, which had previously been the most popular number for most not-for-profits.

citizens adviceWe needed a simple “0300” solution for some very specific local services we had developed. Since we started operating across multiple sites I needed the flexibility of routing calls intelligently between them. We had the 0300 number assigned to us within a few hours, and after a bit of hand holding had a reliable system set up very quickly indeed. Highly commended service.

Frequently Asked Questions

What do I get for free as part of my 0300 number?

We are able to provide as many 0300 numbers as realistically required by your charity,  plus access to a online management portal with iPhone/android app for easy access and management of your number.
The portal gives you access to a fully cloud based telecom solution with the latest features available to 0300 numbers. This includes features such as call statistics (including marketing reports that show call volume, location-based heat maps and more), call routing, disaster recovery and much more.

Will getting an 0300 number effect my current setup/provider/contract?

No – the 0300 number will sit on top of any existing telecom setup you have. Any number that your have will be retained, and our system will simply connect through to the selected telephone lines of your choice.

How much do 0300 numbers cost to call?

The 03 number range was introduced in an attempt to clear up confusion about how much calls cost, especially following years of consumers being unsure about the price of calling 08 numbers. The 0300 number range specifically is reserved for designated public bodies and registered UK charities.
0300 numbers cost exactly the same as any 01/02 (geographic) number and should be treated exactly the same. As most people receive free inclusive minutes with their mobile/landline package, calls to 0300 numbers are free to person dialling and cost the same nominal rate as to any 01/02 number outside of these inclusive minutes.

What are the call costs to my charity?

Although we are able to provide the number, infrastructure, web-portal and 24 hour support for free, incoming calls do incur a cost. This stands at 1.8 pence per minute, and will be billed monthly at a per-second rate.

With over 30 years combined experience, Dial2Donate was created as a way for us to give back to the local community and get involved with appeals close to our heart.
