The 0207 numbers (central London numbers) give the impression that you do business from central London - universally recognised as one of the world's leading financial and cultural cities.

If you are based abroad, one of these numbers can demonstrate your commitment to the UK market, but from a sales standpoint, they are 'less eager' than 08 numbers. One advantage is that 020-7 numbers can be reached reliably from overseas, whereas some non-UK telecom companies are unable to route calls to 08XX and 07XX numbers.
