United Kingdom carrier lookup questions
Short, straight answers about what the lookup can and can't tell you.
How do I find out which network a United Kingdom number is on?
Run it through the lookup above: it checks live carrier and porting records and shows the network the number is on today. The prefix alone tells you which network a number range was first issued to - the table on this page lists them - but a United Kingdom number can move to another network and keep its digits.
How can I tell if a United Kingdom number is a mobile?
Mobile numbers in the United Kingdom usually start with +44 7 (07 when dialled inside the United Kingdom). The lookup confirms it for any number: it shows the line type - mobile, landline or VoIP.
What is the country code for United Kingdom?
The United Kingdom uses the country code +44. Inside the United Kingdom numbers are dialled with a leading 0; from abroad you drop that 0 and dial +44 instead.
How do you write a United Kingdom phone number?
In international format a United Kingdom mobile number looks like +44 7400 123456, and inside the United Kingdom like 07400 123456. Mobile numbers have 10 digits after the +44. The lookup also gives you the clean E.164 form (no spaces) that apps and SMS systems expect.
Which mobile networks are there in the United Kingdom?
The official numbering data names 83 networks with United Kingdom number ranges. The ones with the most ranges are O2, Three, Vodafone and EE. Smaller networks often run on one of those, so a number can show a different carrier name in the live check.
Is the phone carrier lookup really free?
Yes. The lookup is completely free and needs no sign-up or credit card. We cover the cost of the live carrier check, so there are no hidden per-search fees.
Does the person know I looked up their number?
No. The lookup is completely passive - we never call, text or otherwise contact the number, and the carrier check reads routing records rather than reaching the phone, so its owner gets no notification of any kind.
