Error 131026

WhatsApp error 131026: the message couldn't be delivered

WhatsApp accepted your request but couldn't deliver it to the person. Most of the time the number doesn't have WhatsApp, was typed in the wrong format, or the customer's app is too old.

Most common: the number isn't on WhatsApp
Check the country code and leading zero
Fall back to an automated call or SMS
Not a problem with your account

Common causes

  • The number isn't registered on WhatsApp
  • The country code is missing or doubled
  • A local leading zero wasn't removed
  • The customer hasn't accepted WhatsApp's latest terms
  • The customer's WhatsApp app is very outdated
  • The number is a landline

What to do

  1. 01

    Check the format

    Numbers should be in international format, for example 201012345678 for an Egyptian mobile, with no plus sign issues or extra zeros.

  2. 02

    Use a fallback

    In Vrobo, failed WhatsApp confirmations can move to an automated call or SMS so the order still gets confirmed.

  3. 03

    Fix it at checkout

    Ask for a mobile number with the country code preselected to cut bad numbers at the source.
