London Calling FAQs
Is 0207 better than 0208?
Technically, no. Both are standard London numbers. However, 0207 is traditionally associated with central London, so some businesses prefer it for prestige.
What time is it in London?
London follows GMT (Greenwich Mean Time) in winter and BST (British Summer Time, GMT+1) in summer. Always check the time difference before calling business contacts.
Can I call London mobiles with this code?
No. London landlines use 020. UK mobile phones have their own prefixes (usually 07) and are not tied to a specific city location.
