Already Signed Up? Use Promo Code MMB

If you've already created an account but haven't claimed your free fractional share, don't worry. As long as it's been less than 10 days since the promo code was generated, you can still use our Trading 212 promo code. Here's how:

Trading 212 Promo Code for Existing Customers

The promo code MMB is technically a welcome offer, but if you've recently created your Trading 212 account and haven't yet claimed a free fractional share, you can still use it as long as you act within the eligibility window.

You're still eligible if:

• You opened your Invest Account or Stocks ISA within the last 10 calendar days
• You haven't already used another promo code on the account (only one allowed)
• You've never previously held or closed a Trading 212 account
• You haven't yet deposited the minimum amount (€1/£1)

You're not eligible if: you opened your account more than 10 days ago, you've closed and reopened an account, or you used a different promo code on signup. In that case, the only way to claim the bonus is to use our referral link on a fresh sign-up.

How the Trading 212 Invite a Friend Programme Works

Beyond the welcome promo code, Trading 212 also runs a separate referral programme that lets existing users earn additional free fractional shares. Each successful invite credits both you and your friend with a free fractional share following the same probability bands as the welcome offer (worth up to €100/£100).

How to invite a friend:

• Open the Trading 212 app and tap the menu icon
• Select "Free Shares", then "Invite a friend"
• Share your unique link by message, email, or social
• Your friend signs up via your link and deposits the minimum amount
• Both accounts receive a free fractional share within 3 business days

What you should know before inviting:

• Your friend must be new to Trading 212 (not a current or former customer)
• The 30-day withdrawal lock-up applies to the referral reward, same as the welcome offer
• The Invite a Friend programme is governed by separate terms to the Promo Code Terms, check the latest on Trading 212's site before inviting
• Australia is the only excluded country

What Free Fractional Share Will I Get?

According to Trading 212's official probability distribution, the value of your free fractional share is randomly selected but follows specific odds. We've analyzed these probabilities to help set realistic expectations.

This transparency from Trading 212 is refreshing compared to other brokers who don't disclose their bonus distributions. While everyone hopes for the €100/£100 fractional share, receiving a €10-20/£10-20 fractional share (the most common outcome) is still excellent value for just a €1/£1 deposit.

Frequently Asked Questions

How much is the free fractional share worth?

The free fractional share is randomly selected and can be worth up to €100/£100. Based on our research and user reports, most people receive fractional shares valued between €8-25/£8-25, though higher-value fractional shares are regularly awarded. Note that depending on the specific promotion, Trading 212 may issue a Cash Reward instead of a Reward Share.

Do I need to deposit money to claim the free fractional share?

Yes, you need to deposit at least €1/£1 into your Invest Account or Stocks ISA to activate the offer. For more on the ISA option, see our Trading 212 ISA review. Note that CFD Accounts and Cash ISA Accounts are not eligible for this promotion. This minimal requirement makes it one of the most accessible broker bonuses available.

Can I withdraw my free fractional share immediately?

You can sell the free fractional share at any time after it has been credited to your account. However, the monetary value of the reward is subject to a 30-day withdrawal lock-up period from the day it is received. This means you can sell the share and reinvest the proceeds, but you cannot withdraw the cash to your bank account until the 30 days have passed. This lock-up only applies to the reward itself, not to any other funds in your account.

How long does it take to receive the free fractional share?

According to Trading 212's terms, your free fractional share will be placed into your account within 3 business days of meeting the eligibility criteria. In our experience, it often arrives within 24-72 hours.

What happens if the promo code doesn't work?

If the code doesn't work, it's likely been more than 10 days since account creation. In this case, you'll need to create a new account using our referral link. You can find even more available bonuses here.

Is the promo code available in all countries?

The promotion is available in all countries where Trading 212 accepts clients, with the exception of Australia. Users registered under Trading 212 AU are not eligible to participate.

Is Trading 212 safe and regulated?

Yes, Trading 212 is safe and is authorized and regulated by the Financial Conduct Authority (FCA) in the UK, BaFin in Germany, and CySEC in Cyprus (for EU clients). Funds are protected up to €100,000/£85,000 under investor protection schemes. Learn more in our detailed Trading 212 review.

Can I get multiple free fractional shares?

While you can only claim one welcome free fractional share per person, you can earn additional free fractional shares through Trading 212's separate Invite a Friend programme. Each successful referral credits both you and your friend with a free fractional share worth up to €100/£100, following the same probability bands as the welcome offer.
