Odido (odido.nl) suffered a data breach in 2026 that exposed around 6,077,025 accounts. If you had an account, some of your personal data may be circulating in leaked databases. The fastest way to know is to check your own email — free, in about 30 seconds, no password required.
What happened
In February 2026, Dutch telco Odido was the victim of a data breach and subsequent extortion attempt. Shortly after, a total of 6M unique email addresses were published across four separate data releases over consecutive days. The exposed data includes names, physical addresses, phone numbers, bank account numbers, dates of birth, customer service notes and passport, driver’s licence and European national ID numbers. Odido has published a disclosure notice including an FAQ to support affected customers.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the Odido breach exposed and what each item actually enables:
Direct financial fraud, plus convincing scam calls that quote your real card or account details to establish trust.
The strongest identity-theft material there is — enough to open credit accounts or file fraudulent claims in your name.
Home addresses feed people-search and data-broker sites, which republish them publicly. They also make phishing far more convincing and, in the worst cases, enable real-world harassment.
Date of birth is a permanent identifier used to verify identity by phone. Combined with a name and address it is often enough to impersonate you.
Enables SIM-swap attacks (hijacking your number to intercept SMS codes), smishing, and voice scams that appear to come from your bank.
Links this leak to your other accounts — a reused username lets anyone build a profile of you across platforms.
Puts you on spam and phishing lists, and confirms to attackers that you hold an account with this service — which makes impersonation emails more believable.
Also listed in this breach: Bank account numbers, Customer service records, Dates of birth, Driver's licenses, Email addresses, Genders, Government issued IDs, Names, Passport numbers, Phone numbers, Physical addresses.
What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Payment or bank details: Contact your bank, ask them to monitor or reissue the card, and check statements for small “test” transactions.
- Government identifiers: Consider a credit freeze or fraud alert with the credit reference agencies, and watch for accounts you did not open.
- Home addresses: Get your address removed from data brokers — they re-list roughly every four months, so this needs repeating.
- Dates of birth: Never confirm your date of birth to an inbound caller — hang up and dial the organisation back on a published number.
- Phone numbers: Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider.
- Check whether your own email appears in this breach — run a free scan to confirm before you spend time on the steps above.
This breach put your details on data-broker sites
Because Odido exposed home addresses, this is one of the breaches that feeds people-search and data-broker sites. Those sites scrape leaked databases, combine them with public records, and republish the result as a searchable profile — which is how a single breach turns into a permanent public listing. Removal works, but brokers typically re-list within about four months, so it has to be repeated.

How urgent is this now?
This breach is recent, so the data is actively traded and the risk is at its highest right now.
Remember: a breach can't be "un-leaked" — once a database is out, it exists in countless copies. The goal is to make the leaked data useless: change what can be changed, lock down what can't, and remove what has been republished.
