N26 Referral Code

For roughly three years N26's regulator would not let it grow faster than 50,000 new customers a month. That restriction is more revealing than any feature comparison, and it was only lifted in June 2024.

N26 is a German digital bank supervised by BaFin, the German financial regulator, offering accounts, cards and savings across European markets. As a German bank, eligible deposits fall under the EU deposit guarantee framework, which protects up to €100,000 per depositor per bank — the equivalent of the UK's FSCS cover and, as on our Monzo page, the distinction that separates a licensed bank from an e-money firm.

The defining fact about N26's recent history is a restriction rather than a product.

In 2021 BaFin imposed a cap limiting N26 to 50,000 new customers per month, following concerns about the bank's anti-money-laundering controls. The limit was raised slightly, to around 60,000 a month, in late 2023, and lifted entirely with effect from 1 June 2024. Alongside concluding that supervisory period, BaFin fined N26 €9.2 million for failing to file suspicious activity reports promptly in 2022.

A growth cap is an unusual and severe supervisory tool, and it is worth understanding what it signals. A fine is a penalty for something that happened. A cap is a judgement that a firm cannot safely be allowed to keep growing at its own chosen pace until specified problems are fixed — a regulator putting its hand on the throttle. For a venture-funded business whose valuation depends on growth, being held at 50,000 customers a month for roughly three years is a substantial intervention.

The lifting of the cap in June 2024 is equally informative in the other direction: BaFin relaxed the restriction after the bank's AML improvements, which is the regulator stating that the problems it identified had been addressed. A cap that gets lifted is evidence a supervisory process worked, and reading only the imposition without the resolution gives a misleading picture.

This pattern recurs across the batch. Starling was fined £28,959,426 by the FCA in October 2024 after opening more than 54,000 accounts for high-risk customers it had agreed not to onboard. Revolut spent roughly three years obtaining a full UK banking licence, granted in March 2026, held up over regulators' concerns about global risk controls. Different regulators, different instruments, and in each case the pressure point is the same: how fast a consumer bank can add customers without losing track of who they are.

For a prospective customer the practical implications are narrow. Deposit protection is a legal scheme and does not depend on a bank's supervisory record. What a history like this reasonably affects is your expectation of friction — banks working through AML remediation tend to apply more stringent verification, more frequent identity checks, and quicker account restrictions when something looks unusual. That is the customer-facing consequence, and it is worth anticipating rather than being surprised by.

On the referral: as elsewhere in this category, bonuses are conditional on using the account rather than opening it, usually within a short window. Establish the exact trigger and deadline before counting anything, and check which entity holds your account, since deposit protection follows the entity and the jurisdiction rather than the brand.
