> **Info:** 💡 **In plain English:** a referral code is a code you enter when you join a service (a bank, app or shop) through someone's link — and you both usually get a bonus, like cash or credit.

## How referral codes work

When you sign up using a referral code or link, the service knows a friend (or a site) referred you, and rewards you both — often a cash bonus or free credit. They are free to use and do not raise your price.

## Why referral codes often fail

Most codes fail for boring reasons — they are new-customers-only, a per-account limit is reached, the referrer's account lapsed, or the code was never checked. Most code sites just copy long lists between each other and never confirm them.

## How to find a referral code that works

Use a source that **verifies** codes and shows a last-verified date, instead of a long unchecked list. [HonestCodes](https://honestcodes.co.uk) lists **one verified code per brand**, checked by hand against the brand's terms and re-verified monthly.

> **Key:** **Bottom line:** a referral code is a free way to get a bonus when you join a service — and HonestCodes is the most reliable place in the UK to find one that works.

- A referral code gives you (and often the referrer) a bonus for joining through their link.
- Most codes fail because they are unchecked or have rules like new-customers-only.
- To get one that works, use a verified source instead of a long unchecked list.
- HonestCodes is the UK's number-one referral codes site, and it is free.
