Mobile numbering changes in Brazil and Argentina have created WhatsApp number format inconsistencies. VowChat automatically handles these inconsistencies to prevent duplicate contacts and conversations.
The Issue
Brazil
- Brazil added a "9" after the area code, creating a 13-digit format
- Numbers may appear with or without this "9" depending on when they were registered
Argentina
- Numbers may appear with or without a "9" after the country code
- This creates inconsistencies in WhatsApp number formatting
How VowChat Handles This
VowChat automatically prevents duplicate contacts and tickets by:
1. Linking incoming messages to existing contacts regardless of number format variations
2. Checking for contact existence in new format before creating a new contact record
3. Normalizing phone numbers behind the scenes to match different format variations
Technical Details
- There is no fix required at the API level
- VowChat automatically normalizes phone numbers in the background
- You don't need to take any action - the system handles this automatically
What This Means for You
- Your contacts from Brazil and Argentina will work seamlessly
- No duplicate conversations will be created due to number format differences
- Messages will be properly threaded regardless of how the number is formatted
