When trying to onboard a WhatsApp Federation contact from Brazil with an 8-digit phone number, users may receive the following error.
This error is triggered due to a change by Brazil telecom providers expanding the available phone numbers in that country. As part of this change, 8-digit legacy numbers were also provided an equivalent 9 digit number.
To translate an 8-digit number to a 9-digit one, add a 9 before the phone number, but after the country code and area code:
| 8 Digit Number | +55 35 1234 5678 |
| 9 Digit Number | +55 35 91234 5678 |
If the new 9-digit number is still not accepted, please contact Symphony Support at support@symphony.com
