Bulgaria (+359) WhatsApp Valid Data - kkdata Number Filtering

Bulgaria’s country code is +359 and its ISO code is BG. To get local WhatsApp valid data, you first need +359 numbers, then use kkdata number filtering to check WhatsApp activation and activity—only then do you have a truly usable list. Number generation only produces candidates; generation does not equal validity.

How to Get Started

1. Log in to the console, go to Global Number Generation, select the country Bulgaria (+359), then select by city or number range to generate candidate numbers.
2. Create a new WhatsApp filtering task and choose activation/valid or an activity window (such as active in the last three days; refer to the console options).
3. For uploads, it is recommended to use E.164 format (+359…) consistently, with a maximum of about 1 million numbers per task.
4. After the task is completed, export the results, including fields such as WhatsApp valid/activated, for subsequent outreach.
5. Generation is free, while filtering is billed per number. Test with a small batch first before scaling up.

FAQ

Q: Are the generated +359 numbers WhatsApp valid data? A: No. A valid number range only means the format is correct. Whether the number is activated must be confirmed by filtering—treat these as two separate things.

Q: How can I control costs for Bulgaria number filtering? A: Filtering is billed per number. It is recommended to filter a small sample first to estimate the pass rate, then decide on the scale for expansion.

Compliance note: Use only for lawful customer acquisition, comply with local regulations and platform rules, and do not send harassing messages.
