What sender ID or number will my international SMS recipients see?

When messaging contacts in the US or Canada, they will always see your sender ID as your OpenPhone number; however, this may change when messaging internationally. For some messages to international countries, you cannot have 2-way texting (i.e. you message a client and they can message you back at the same number).

Countries with 2-way SMS messaging

If you are messaging one of the below countries, then they will receive a message from your OpenPhone number. When they reply to that message, it should arrive in your OpenPhone inbox, just as any other message.

International countries with 2-way SMS messaging include:

  • Austria
  • Belgium
  • Canada
  • Chile
  • Czech Republic
  • Denmark
  • Estonia
  • Finland
  • Hong Kong
  • Hungary
  • Israel
  • Lithuania
  • Netherlands
  • Phillippines
  • Poland
  • Portugal
  • Singapore
  • Slovakia
  • Sweden
  • Switzerland
  • United Kingdom

Countries without 2-way messaging

For any country not listed above, you can still send international messages but they will receive the message from a different sender ID than your OpenPhone number. This change occurs automatically to comply with local regulations and ensure deliverability.
