Was your data in the Odido breach?

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:

What to do if you were affected

These steps are ordered for this specific breach — the most urgent action given what leaked comes first.

1. 01Payment or bank details
   Contact your bank, ask them to monitor or reissue the card, and check statements for small “test” transactions.
2. 02Government identifiers
   Consider a credit freeze or fraud alert with the credit reference agencies, and watch for accounts you did not open.
3. 03Home addresses
   Get your address removed from data brokers — they re-list roughly every four months, so this needs repeating.
4. 04Dates of birth
   Never confirm your date of birth to an inbound caller — hang up and dial the organisation back on a published number.
5. 05Phone numbers
   Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider.
6. 06Confirm you were actually in it
   Run a free scan 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.
