Marktplaats SMS check: what to know

Updated 7 November 2026 · The ReserveSMS team

In short

  • The SMS security check is required for every Marktplaats account, and can’t be turned off.
  • Marktplaats texts a code when you log in on a new device or from a new place.
  • Lost the old number? Change it while still logged in, or ask customer service through chat.

Marktplaats protects every account with an SMS security check, and your account is only created once it’s switched on.

When it texts you

Marktplaats sends a code by text when you log in on a new device or from a different place, to confirm it’s you. Once on, the check can’t be switched off.

Without your old number

If you’re still logged in on a trusted device, change the number yourself. If not, start a chat with customer service from the help article about old numbers, and it can change it for you.

Watch for scammers

Marktplaats says it never asks for your email address or phone number in a chat in Berichten, and its staff never call to ask for your bank details.

Use your own number here

Marktplaats texts a code every time you log in somewhere new, and a one-time number from ReserveSMS receives codes for 20 minutes only. For a Marktplaats account, use a mobile number you keep.
