Are all 0800 numbers free for callers in the United Kingdom?

Answer 1

Generally yes.

However it would depend on owner of the line you are using. Some hotels will charge a fee likewise calls from mobile phones sometimes are not free of charge either.

NOTE: When calling within the USA, USA 800 numbers start with 1-800....)

Answer 2

In many countries, 0800 is a telephone code used for domestic toll-free calls. There are no long distance charges for calling a toll-free number, but in some countries you may still pay a charge comparable to a local call. Also, in most countries, most calls to toll-free numbers from mobile phones (cell phones) will still incur airtime charges, and may incur roaming charges, if applicable.

Answer 3

If called from a land line, any number starting 080 will be free to call from the UK. So 0800, 0808 (and more codes in the future as more Freefone numbers are needed) are Freefone numbers.

However, the money grabbing mobile phone companies will charge for calls to Freefone numbers.
