Ever looked at your phone, seen a missed call starting with 07, and just... hesitated? We’ve all been there. You aren't sure if it’s your delivery driver lost in the neighborhood or a persistent scammer from halfway across the globe.
In the UK, the 07 prefix is the lifeblood of mobile communication. It’s what connects us. But it’s also a range that has been historically messy, confusing, and occasionally expensive.
What are real 07 phone numbers anyway?
Basically, if you’re in the UK, almost every mobile phone number starts with 07. These are 11-digit strings that tell the network exactly where to send your "u up?" texts.
The structure is pretty specific. You’ve got the "07" at the start, followed by nine more digits. For example, 07700 900123 is a classic format. If you’re calling from abroad, you drop the zero and add the country code, making it +44 7700 900123.
It’s not just one big bucket, though. The digits immediately after the 07 usually indicate which network the number originally belonged to. O2, Vodafone, EE, and Three all have their own little "neighborhoods" of numbers.
Honestly, it used to be easier to tell who was on what network. If your friend had an 07801 number, you knew they were on O2. Now? Because of mobile number portability, people take their numbers with them like a favorite pair of jeans. You can’t really judge a network by its prefix anymore.
The 070 Trap: Why some 07 numbers used to cost a fortune
Here is where it gets kinda tricky. For years, there was this "hidden" range starting with 070.
These weren't mobile numbers. They were "Personal Numbers" or "Follow Me" numbers. Businesses loved them because you could program an 070 number to redirect to any phone—your office, your home, or even a satellite phone on a boat in the middle of the North Sea.
The problem? They looked exactly like real 07 phone numbers used for mobiles.
Scammers realized this and went to town. They’d leave "missed calls" from 070 numbers, hoping you’d call back. When you did, you’d be hit with charges of up to £1.50 per minute. It was a mess. People were getting "bill shock" at the end of the month because they thought they were calling a standard mobile.
Ofcom, the UK's communications regulator, finally stepped in around 2019. They capped the wholesale cost of calling 070 numbers to match the cost of calling a regular mobile.
According to Ofcom’s own reports, scam calls using the 070 range dropped by a massive 75% almost immediately after the price cap was introduced.
How to spot a real mobile number vs. a scam
You've probably noticed that the spam calls haven't totally gone away. They’ve just changed tactics.
Most real 07 phone numbers used by actual humans will follow these sub-ranges:
- 074xx, 075xx, 077xx, 078xx, 079xx: These are the "safe zones" for standard UK mobiles.
- 07624: This is a bit of an outlier. It’s often used in the Isle of Man. It’s "real," but your provider might charge you extra because it’s technically outside the UK mainland network.
If you get a call from an 07 number and you’re suspicious, look at the length. Real UK mobiles are always 11 digits long. If it’s 10 digits or 12 digits, it’s a spoofed number or an international call trying to look local.

Why your phone says "Scam Likely"
Modern smartphones are actually pretty smart.
When a call comes in, your carrier (like EE or O2) checks the number against a database of known "bad actors." If that specific 07 number has been reported 500 times in the last hour for "unusual calling patterns," your phone will flag it.
But scammers use "neighbor spoofing." This is when they use software to make their number look almost identical to yours. If your number is 07700 900123, they might call you from 07700 900124. You see the first few digits, think "Hey, that looks like my number," and pick up.
Don't. It’s a trap.
The weird world of 076 numbers
We can't talk about 07 numbers without mentioning the pagers. Yes, pagers still exist.
The 076 range is largely reserved for radiopaging services. You’ll still find doctors, lifeboat crews, and emergency engineers using these because they work in areas where mobile signals die.
The catch? Calling an 076 number can still be incredibly expensive. Some networks charge over £1.00 just to connect the call. If you see a missed call from 076, think twice before hitting redial unless you know a surgeon or a lighthouse keeper.
Real 07 phone numbers in the wild: A quick checklist
If you're ever in doubt, here is a quick way to vet the number:
- Check the length. Is it exactly 11 digits starting with 0?
- Look for 070 or 076. These are the "expensive" cousins. 070 is safer now thanks to the 2019 cap, but 076 can still bite your wallet.
- Google it. Seriously. If it's a scammer, chances are someone else has already posted about it on a "Who Called Me" site.
- Listen for the "Silence Gap." If you answer and there’s a two-second delay before a human (or a robot) speaks, it’s an automated dialer.
Moving forward with your mobile
The 07 range is going to be with us for a long time. Even with the rise of WhatsApp and data-based calling, these numbers are our digital identities.
If you're worried about your own 07 number being leaked or used for spam, you might want to consider a "virtual" mobile number for signing up for websites. There are apps that give you a secondary 07 number that routes to your main phone. It keeps your real number private while still letting you receive those "Your delivery is 10 minutes away" texts.

Also, check your monthly bill. Most UK contracts now include "unlimited minutes," which covers standard 07 mobile ranges. If you see extra charges, it means you’ve bumped into an 070, 076, or an international number.
Actionable steps for your phone safety:
- Enable "Silence Unknown Callers" in your iPhone or Android settings. This sends any number not in your contacts straight to voicemail. If it’s important, they’ll leave a message.
- Report spam texts. If you get a dodgy text from an 07 number, forward it to 7726. This is a free service used by all UK networks to track and block scammers.
- Check the prefix. Use a site like the Ofcom Numbering Plan if you’re really curious about where a number originated. It’s a bit dry, but it’s the definitive source of truth.
- Never give data away. No bank will ever call you from a random 07 mobile number and ask for your PIN. Ever.
Understanding real 07 phone numbers doesn't have to be a headache. Just remember that 074 through 079 are generally your friends, 070 is a "maybe," and 076 is almost certainly going to cost you a few quid. Stay skeptical, stay safe, and maybe just let it go to voicemail.
