Millions of people across Britain play the People’s Postcode Lottery every month, and one question keeps coming up: how many postcodes are in the Postcode Lottery? The short answer is that every eligible postcode in Great Britain can be entered, which means well over a million.
The number behind the draw
The People’s Postcode Lottery doesn’t publish a single headline figure. The pool is simply every live postcode in England, Scotland and Wales where a player has signed up. The UK as a whole is commonly cited as having roughly 1.7 million postcodes, but that figure includes Northern Ireland. The Postcode Lottery is open only to players in Great Britain, so the eligible total is somewhat lower.
Each full postcode covers a small cluster of addresses. The average is around 15 properties, though some cover a single large building and others only a few homes. That is why a win can feel so personal, with neighbours on the same street sharing the celebration.
How the Postcode Lottery works
Players don’t pick numbers. They subscribe with their own postcode, which acts as their ticket, and are automatically entered into every draw. The subscription costs £12 a month. Prizes are announced daily, and there are larger weekly and monthly draws, including the Postcode Millions prize.
A postcode is drawn first, and everyone who holds a ticket for it wins. This is why the number of postcodes matters less than people think. The odds depend on how many postcodes are in the draw each time, not on how many people live on your street.
Does more players in your postcode mean better odds?
No. If more neighbours join, your own chances don’t improve, because the draw selects a postcode rather than an individual. More players in a winning postcode simply means more people sharing in the result. Having more tickets on your own postcode increases the amount you win if it comes up, not the likelihood that it does.
Why the total number of postcodes changes
The postcode count is never fixed. Royal Mail creates new postcodes as housing developments are built, and old ones are retired when buildings are demolished or merged. The Office for National Statistics publishes a regularly updated postcode directory that tracks these changes, which is why published totals vary slightly between sources.
For the Postcode Lottery, the practical effect is that the eligible postcode pool shifts a little over time. A newly built estate can become part of the draw once residents sign up.
Where the money goes
A share of every ticket goes to good causes. The People’s Postcode Lottery says players have raised well over £1 billion for charities and community projects since it launched in 2005. At least a third of each ticket price is allocated to those causes, which is part of the appeal for many subscribers.
What to check before you play
If you’re thinking of joining, a few points are worth knowing:
- Eligibility: you need to live in England, Scotland or Wales and be 18 or over.
- Cost: it is a monthly subscription, so it’s worth setting a budget before you sign up.
- Prizes vary: many daily prizes are modest, while the large Postcode Millions prize is far rarer.
- Odds: the chance of any one postcode winning a top prize is small, as it would be in any lottery.
Conclusion
So how many postcodes are in the Postcode Lottery? Effectively, every live postcode in Great Britain, which is more than a million. The exact total moves as new addresses are created, and no official lottery figure is published. What matters for players is that the draw works by postcode, so your odds rest on the size of the pool, not on how many of your neighbours play.
