What is 1013 error code?

Manish Manohar Updated by Manish Manohar

The 1013 error code signifies that the given number is not registered on WhatsApp. Therefore, attempting to send a message via API to a number without an active WhatsApp account will result in a 1013 error response. In the past, WhatsApp provided an API to check whether the number has an active WhatsApp account or not, but this capability has been phased out. Currently, the verification of contact existence occurs during the message transmission to a phone number.

For businesses or individuals utilizing APIs for message sending, it is recommended to manage this error on their side to enhance the overall user experience.
