Trading 212 Promo Code 'MMB' October 2026: Free Fractional Share up to €/£100

Last verified working on 13 October 2026

Available to new customers in most countries Trading 212 serves. The reward and requirements can vary by country, so check the offer screen when you sign up.

How we verify this offer: we test the MMB code against the live Trading 212 sign-up flow, cross-check the reward terms on Trading 212's official terms page and the official promo code help page, and confirm the code is still crediting fractional shares for new sign-ups. Last full check: 13 October 2026.

How to Claim Your Free Fractional Share on Trading 212

Trading 212 makes it simple to get a free fractional share worth up to €100/£100 when you sign up. Based on our testing, the process takes less than 15 minutes and requires just a €1/£1 minimum deposit. Here's exactly how to do it:

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 calendar days since you opened your account, 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 (UK only) 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. Opening a second account will not help, because Trading 212 excludes current and previous customers from the promotion.

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. When a campaign is running and Trading 212 has issued you a referral link, each successful invite can earn both you and your friend a free fractional share worth between €8 and €100/£8 and £100, with higher values less common. Referrers can earn up to five rewards per campaign.

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
• Invite a Friend has its own, shorter country list. The current campaign runs from 21 September to 3 November 2026 and covers the UK, Ireland, Germany, the Netherlands, Austria, Luxembourg, Liechtenstein, Norway, Sweden, Denmark, Finland, Iceland, the Czech Republic, France, Slovakia, Italy, Slovenia, Croatia, Greece, Hungary, Bulgaria, Estonia, Lithuania, Latvia, Switzerland, Romania, Mexico, Honduras, Peru, Bolivia, Ecuador, Colombia, the UAE, Qatar, Oman, Kuwait and Bahrain. Countries not on that list, including Spain, Portugal, Poland, Cyprus, Malta and Australia, are excluded. Source: Invite a Friend Terms and the help-centre article.

Trading 212 Cash ISA Rate and Bonus

Trading 212 also offers a Cash ISA for UK customers. It currently pays 3.60% AER variable, set at 0.15% below the Bank of England base rate of 3.75%, so the rate moves when the base rate changes. Interest is calculated daily and paid monthly, and the Cash ISA is flexible, so you can add and withdraw money at any time.

The Cash ISA does not qualify for the free fractional share, because the promo code only applies to an Invest account or a Stocks ISA. To see how the rate compares with other providers, read our best Cash ISAs UK comparison. Rate checked on 20 October 2026.

Trading 212 is also running a separate Cash ISA Bonus Rate promotion for new UK customers who open a Cash ISA between 8 October and 9 December 2026 through a partner link or code tied to that promotion. It adds a fixed bonus rate on top of the standard rate for 12 months, on money paid in during the current tax year, and the deposit or transfer has to be made within 10 days of opening the Cash ISA. Code MMB does not give this bonus. Trading 212 only lets you join one promotion, so if you claim the free share you cannot also get the Cash ISA bonus rate.

Why Choose Trading 212?

Trading 212 is one of the most popular investment apps in Europe, offering commission-free trading on a wide range of stocks and ETFs. Other fees may apply, including a 0.15% currency conversion fee. See Trading 212's terms and fees. Here's what we found during our testing:

Whether you're a seasoned investor or just getting started, Trading 212 is a reliable platform for long-term investing. You can read our full Trading 212 review here.

One standout feature is Trading 212's competitive interest rate on uninvested cash, which rivals traditional savings accounts. If you're looking to maximise your returns on cash holdings, check out our guides to the best high-yield savings accounts in Europe and the best high-yield savings accounts in the UK to compare your options.

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 an €8-25/£8-25 fractional share (the most common outcome, with an 80% chance) is still excellent value for just a €1/£1 deposit.

Once your Trading 212 account is funded, a research platform like InvestingPro can help you decide what to actually buy.

Why Is My Trading 212 Promo Code Not Working?

When the MMB code fails to apply, one of five causes is almost always behind it. Work through them in order:

• You're outside the 10-day window. The code must be entered within 10 calendar days of creating your account. After that, Trading 212 cannot apply it retroactively.
• You already used another promo or referral code. Only one code can ever be applied per account. A second code will always be rejected.
• You previously held a Trading 212 account. The offer is for new customers only. Closing and reopening an account does not reset your eligibility.
• Your deposit went to the wrong account type. The minimum €1/£1 must be deposited into your Invest Account or Stocks ISA (UK only). CFD Accounts, Cash ISA Accounts and SIPPs are not listed for this promotion.
• You're in an excluded region. The MMB code covers new customers served by Trading 212 UK, EU and Markets (Cyprus), but not Australia, which runs separate promotions. The Stocks ISA option is UK only. Available promotions also vary by country, and in our check on 2 October 2026 the code showed as unsupported for some regions, so check the offer screen on our sign-up link before you deposit.

If none of these apply and the code still won't go through, contact Trading 212 support directly in the app (menu, then Help). If you turn out to be ineligible because of the 10-day window or a previously used code, the offer is unfortunately gone for that account. The sign-up link only works for genuinely new customers.

Is Trading 212 worth it?

For most new investors in the UK and Europe, yes. It is a regulated, low-cost broker, and the free share is a small bonus on top rather than the main reason to join.

Frequently Asked Questions

Does the Trading 212 promo code work for existing customers?

Only if your account is new. You can still enter MMB if you opened your Invest account or Stocks ISA within the last 10 calendar days and have not used another promo code or joined another promotion. Current and previous Trading 212 customers are excluded, and closing and reopening an account does not reset this.

What is the difference between a Trading 212 referral code and a promo code?

A promo code such as MMB is a partner code that any new customer can enter, covered by Trading 212's Promo Code Terms. A referral (Invite a Friend) link comes from an existing customer, runs in set campaigns (the current one runs from 21 September to 3 November 2026) and rewards both people with a free fractional share. You can only use one of them on your account.

Do I get free shares with code MMB?

Yes, one free fractional share. Trading 212 picks the company and value at random, from £8 to £100 (or €8 to €100). You can sell it at any time, but its cash value cannot be withdrawn for 30 days after it is credited.

Does code MMB give the Trading 212 Cash ISA bonus?

No. The Cash ISA Bonus Rate is a separate UK promotion for new customers who open a Cash ISA between 8 October and 9 December 2026 through a partner link or code tied to that promotion. It adds a fixed bonus rate for 12 months on top of the standard rate, which is currently 3.60% AER variable. You can only join one Trading 212 promotion, so claiming the free share with MMB rules out the Cash ISA bonus rate.

Can I combine the promo code with Invite a Friend?

No. Trading 212's Promo Code Terms do not apply if you joined through an Invite a Friend link or code, and the Invite a Friend Terms do not apply together with a promo code from a different promotion. Only one of the two applies to your account.

How much is the free fractional share worth?

The free fractional share is randomly selected and can be worth up to €100/£100. Trading 212's published probabilities show that 80% of rewards are worth €8-25/£8-25, and higher-value fractional shares are less common: only 2% fall between €75.01 and €100/£75.01 and £100. 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 (UK only) to activate the offer. Trading 212's MMB sign-up page lists only these two account types, so a SIPP on its own does not qualify. 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 calendar days since you opened your account. Trading 212 cannot apply the code after that, and opening a new account will not qualify, because current and previous customers are excluded. You can find other available bonuses here.

Is the promo code available in all countries?

The promo code covers new customers in the countries served by Trading 212 UK, Trading 212 EU and Trading 212 Markets (Cyprus). Australia is excluded and runs its own promotions, and the Stocks ISA option is UK only. Available promotions vary by country, so check the offer screen on our sign-up link before you deposit.

Is Trading 212 safe and regulated?

Yes, Trading 212 is safe and is authorised and regulated by the Financial Conduct Authority (FCA) in the UK, BaFin in Germany (Trading 212 EU GmbH), CySEC in Cyprus (Trading 212 Markets Ltd) and ASIC in Australia. For UK clients, uninvested cash held at partner banks is covered by the FSCS up to £120,000 per eligible person per banking licence, and investments and cash are covered up to £85,000 in total if Trading 212 itself fails. EU clients are covered by the investor compensation scheme of their entity, up to €20,000. Market losses are not covered. As with any investment, your capital is at risk. 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. When a campaign is running and Trading 212 has issued you a referral link, each successful invite can earn both you and your friend a free fractional share worth between €8 and €100/£8 and £100, with higher values less common. Referrers can earn up to five rewards per campaign.
