If a missed call on your phone starts with 09, the single most important thing to know is this: don't call it back. 09 numbers are premium-rate, and a "missed call" from one is almost always engineered to make you ring it - at your expense. This guide explains how 09 numbers work and why an unexpected one is a near-certain trap.
What an 09 number is
09 is the UK's premium-rate range. The cost of the call is deliberately high because part of it funds the service at the other end - think competition lines, some adult or entertainment services, and certain "expert" advice lines. Charges can run to several pounds per minute, plus your provider's access charge, and they are not included in any inclusive minutes. Our 09 premium-rate numbers guide sets out how the charging works, and the free phone number checker will flag any number in this range.
Why a missed call from an 09 number is a trap
This is the heart of the problem. A scam known broadly as a "call-back" scam works like this:
Your phone rings once and stops before you can answer, leaving a missed call from an unfamiliar number. Curiosity (or worry) makes you ring it back. The number is premium-rate, and the moment you connect you're being charged a high per-minute rate - while a recorded message or a deliberately slow "agent" keeps you on the line as long as possible.
The whole point is to make you dial an 09 number. The call costs nothing to send to you; the profit is entirely in your call-back. This is closely related to the one-ring "Wangiri" scam, which uses the same hook with international and other expensive numbers.
The simple rule: don't call back
There is almost no legitimate reason for an unknown caller to need you to ring a premium-rate number. So the rule is refreshingly simple:
- Never return a missed call to an 09 number. If you don't recognise it, leave it.
- Ignore voicemails or texts urging you to "call back urgently" on an 09 number - urgency is the bait.
- If a service genuinely uses a premium line (a competition you entered, say), you'll know about it in advance and can decide deliberately - not in response to a missed call.
What to do instead
- Check the number with the free phone number checker to confirm it's premium-rate.
- Block it so it can't try again - see how to block unwanted calls.
- Bar premium-rate calls altogether. Most providers will block outgoing calls to premium-rate numbers free of charge on request - a smart move if you want to be sure you can never be caught out, and especially useful for protecting older relatives.
- Report it to Action Fraud and forward the details to 7726. Premium-rate services are also overseen by a regulator, the Phone-paid Services Authority, which handles complaints about how these numbers are used.
The bottom line
An 09 number is premium-rate, and a missed call or "call me back" message from one is almost always a deliberate attempt to make you dial an expensive line. The safest response is the easiest: don't call back, block the number, and consider asking your provider to bar premium-rate calls entirely. If you've been caught out, report it - you may be able to dispute the charge.
Frequently asked questions
Should I call back a missed call from an 09 number?
No. 09 numbers are premium-rate, and a missed call from one is almost always a trap designed to make you ring an expensive line. There's no legitimate reason an unknown caller needs you to call a premium-rate number, so leave it and block it.
How much does it cost to call an 09 number?
It varies but can be several pounds per minute, plus your provider's access charge, and it isn't covered by inclusive minutes. That high cost is the whole point of the scam - the longer you stay on the line, the more the operator earns.
Can I stop premium-rate calls completely?
Yes. Most phone providers will bar outgoing calls to premium-rate numbers free of charge if you ask. That guarantees you can't accidentally ring one, which is particularly useful for protecting children or vulnerable relatives.
I called back an 09 number and was charged - what can I do?
Report it to Action Fraud and contact your phone provider to query the charge; you may be able to dispute it. Complaints about premium-rate services can also be raised with the Phone-paid Services Authority, which regulates them.
