If Maritz Holdings Inc. (“Maritz”) had your data

  1. Look for Maritz Holdings Inc. (“Maritz”)’s own notice or letter: it should say what of yours was involved. Keep it.
  2. Call your bank on the number printed on your card (never one from a message), check recent payments and ask for a new card.
  3. An ID number cannot be changed, so lock it: a credit freeze or fraud alert in the US, a credit warning (kreditadvarsel) on borger.dk in Denmark, Cifas protective registration in the UK.
  4. Expect scams that use your details: calls, texts or emails pretending to be Maritz Holdings Inc. (“Maritz”), your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.

One email to confirm first. We use your address only for this alert, and one click deletes it.
