Obtaining an 0300 number

Choosing your 0300 number?

Do the charitable thing – move to 0300

Making the move to 0300 is both an easy and an economical transition. As most people are aware, there are many prefixes available which are categorised as free-to-phone numbers – therefore a natural choice for some industries such as the charity sector or are they? Despite being the instinctive option for some charities as their selected contact number, these don’t always rest so well with callers. In fact, although they are affordable those first two digits nevertheless can often act as a deterrent rather than an invitation to call.

Given the empathetic focus within the charity sector it isn’t surprising that so many have made the transition to a more confidence-boosting telephone number i.e. 0300. It is reassuring to know that the move to 0300 is a small change that makes a massive difference to caller assurance and clarity of cost.

Before exploring which charities have already changed their numbers to 0300 it is imperative to examine Ofcom’s influence over the introduction of this caller-friendly prefix.

Ofcom and 03

Ofcom recognises people need to be able to contact public sector industries as affordably as possible. Therefore, they have placed great emphasis on transferring to 03.

‘Ofcom is actively encouraging public and not-for-profit bodies to use 03 numbers. These cost no more to call than a geographic (01 or 02) number, and must be included in a customers’ inclusive minutes or discount schemes’.

This statement means, more and more callers can contact essential services in the most economical way possible.

Despite Ofcom’s plan to also launch their, ‘UK Calling – Clear Call Rates For Everyone’ campaign in January 2015, the ambiguity surrounding the cost of 08 numbers continues. Thankfully no such stigma has attached itself to 03s (in particular) 0300s, which this makes them a safe choice for those who want to really reach out and truly welcome their callers.

Are you aware that Ofcom has assigned 0300 phone prefixes purely for non-profit making concerns?
