Unexpected call from +31?

If you have no contacts in the Netherlands, a missed call from +31 that rings once is the classic "wangiri" pattern: the callback is billed at international or premium rates. Do not call back; look the number up instead.

Messages from foreign numbers offering jobs, investments or "a wrong number" chat are another common opener. A real +31 number can also be spoofed, so caller ID alone proves little — check whether the number is valid, which network holds it and whether it is a mobile, landline or VoIP line.

Foreign number on your screen? Why caller ID isn't the whole story

How to dial +31

  1. From a mobile anywhere: press + (hold 0), then 31, then the number without the leading 0.
  2. From the US or Canada: dial 011, then 31, then the number without the leading 0 — for example 011 31 6 12345678.
  3. From most of Europe, Africa and Asia: dial 00, then 31 and the number without the leading 0.
  4. Inside the Netherlands: drop the 31 and dial the number with its 0 in front — 06 12345678.
