Are referral codes safe? How to spot a scam

Referral codes are safe when they lead to the brand's real website and ask for nothing unusual. The risk comes from fake offers, copycat websites and listings that promise unrealistic rewards, particularly around financial products. A handful of quick checks will protect you in almost every case.

What a genuine referral looks like

A real referral is simple. You click a link or enter a code, create an account on the brand's own website, and complete an action such as a purchase or booking. You are never asked to pay to receive the reward, and you are never asked to give someone else your login details.

Warning signs of a scam

• The reward is far bigger than normal. If a brand usually offers a modest credit and a listing promises hundreds, ask why.
• You are asked to pay a fee or to buy something unrelated to unlock the bonus.
• The link goes to a different domain from the brand's official website, or to a page that looks like the brand but has a slightly different address.
• There is pressure to act now, such as a countdown or a message saying the offer ends in minutes.
• You are asked for sensitive details such as your password, a one time security code, or full card details before you have even created an account.
• The contact came out of the blue, for example a message from a stranger or someone you only met online who is keen for you to invest.
• A "verified" label appears with no explanation of what was verified or when.

How to check an offer in five steps

1. Read the web address. Look carefully at the domain before you type anything. Be wary of extra words, hyphens or unusual endings.
2. Compare it with the brand's own page. Most genuine brands describe their referral scheme on their own site. If the offer differs, trust the brand.
3. Search for recent experiences. Look for complaints or reviews of the offer from the past few months.
4. Read the terms. Look for conditions that make the reward unrealistic, such as a very large minimum deposit.
5. Start with the minimum. Create the account and look around before you give payment details.

Extra care with banking, investing and crypto

Referral bonuses are common in fintech, and many are legitimate. But these are products where you can lose money, and scammers use the same tactics.

The Financial Conduct Authority warns that investment scammers often use urgency, offers that look too good to be true and "exclusive" opportunities, and may offer a bonus or discount for investing quickly. A referral bonus fits that pattern, so treat it as a reason to check, not a reason to trust.

Before you sign up to a financial product:

• Search for the firm on the FCA Financial Services Register and check the FCA warning list.
• Confirm the contact details match the ones on the register.
• Do not let the size of a bonus drive a decision about whether a product suits you.
• Never invest money you cannot afford to lose.

Crypto assets in particular are high risk and largely unregulated for investor protection in the UK, so a bonus is not a reason to take on that risk.

Protect your information

• Use a unique password for each service, ideally with a password manager.
• Turn on two factor authentication where it is offered.
• Never share a one time code with anyone, including the person who referred you.
• Use a card or payment method with strong protection for online purchases.

Recovery scams

If you have been scammed once, you may be contacted by someone who claims they can recover your money for a fee. This is a known second scam. Do not pay.

What to do if you have been caught out

1. Contact your bank at once if you shared card or account details.
2. Change any passwords you reused, starting with your email.
3. Report the page to the brand it copied.
4. Report it to Report Fraud, which replaced Action Fraud in the UK.
5. Keep screenshots and messages as evidence.

How we approach this

For each code, Referral CodeFinder shows the offer, the redemption steps and the terms, along with the date we last verified it, so that you can compare it with the brand's own page. We encourage you to do that check. If you spot an offer that has changed, tell us.

If a code does not work for a harmless reason, read why a referral code is not working. To understand how offers are structured in the first place, see how referral programmes work.
