0800 Numbers

0800 numbers are a type of non-geographic number where only the receiver is charged for the call, but not the caller. 0800 numbers are not linked to any locale, which is why many businesses purchase these numbers for customer service use. These toll-free numbers are great marketing and customer service tools that allow businesses to achieve a higher reach at a lower cost to their customers.

Consumers consider 0800 numbers trustworthy, which means they are more likely to answer the phone when they receive a call from an 0800 number. Having an 0800 number also allows businesses to market their services outside of their vicinity. This is because 0800 are tied to a national presence, which makes them particularly useful for companies with multiple locations or for online businesses that distribute products nationally or internationally.

Before the introduction of the 0800 number in 1985, people would call the operator and ask for a company by name. While 0800 numbers were originally assigned to British Telecom, in 1994 ‘0800’ numbers were made available to other phone companies and three years later 0808 prefixes were also added to provide more freephone capacity.

Costs to call 0800 numbers

All 0800 numbers have always been free to call from landlines. The company receiving the call picks up the cost of the redirected call. Since 2015, mobile numbers have also ben free to call from mobile phones. This applies to any mobile network operator and no charges should be applied against your bill, or they can be disputed.
