UK Mobile vs Landline Codes Explained
UK phone numbers can be divided into two main categories: mobile numbers and landline (geographic) numbers. Understanding the difference helps you identify callers, estimate call costs, and avoid premium-rate surprises.
⚠️ Not all 07 numbers are standard mobiles - some (like 070) may be personal redirection numbers with higher charges.
UK Mobile Numbers (07 Prefix)
Most UK mobile numbers begin with 07 and are 11 digits long.
- Example: 07123 456789
- Dial internationally as: +44 7123 456789
- Usually included in mobile call bundles.
- Used by major mobile network operators.
⚠️ Be cautious with 070 numbers - these are often personal redirect numbers and can cost more to call.
UK Landline Numbers (01 / 02 Prefix)
Landline numbers are geographic and linked to a specific area of the UK.
- Start with 01 or 02.
- Example (London): 020 7946 1234
- Example (Manchester): 0161 123 4567
- Typically included in landline and mobile bundles.
