Zalo number screening
Vietnam's homegrown national messenger, built by VNG, where the phone number is the account and most profiles have gender and birthday filled in.
Coverage
- Vietnam
- Ho Chi Minh City
- Hanoi
- overseas Vietnamese communities
Zalo comes from VNG, a Vietnamese company, and its stickers, interface and seasonal features are built around local habits in a way imported apps never matched. Bank support lines, government notices and neighborhood shop orders all run through it today.
Platform characteristics
- The phone number is the account, real names are the norm, and most profiles have gender and birthday filled in — the most complete profile data of any messenger in this group.
- Vietnam converted all mobile numbers from 11 digits to 10 in 2018, and plenty of older lists still carry the retired prefixes, which return nothing at all. Convert the number format before uploading.
- The business side runs on Zalo OA (Official Accounts), carrying everything from storefronts to bank and government notices, and OA behavior looks nothing like a personal account.
- Payments and mini-programs sit alongside chat, so how deeply an account is used isn't measured by messaging alone.

What screening solves here
Nearly everyone in Vietnam uses Zalo, so a registration check alone removes very little — the opposite of Telegram. The real value sits in activity bands and in gender and age: because profiles routinely carry gender and birthday, age-band filtering is far more usable here than on comparable platforms. Use the express lane to sweep large lists, and the stable lane for smaller batches that need verification.
FAQ
How do I bulk-screen Vietnamese Zalo numbers for activity?
Use the activity-band filter, which returns results segmented by how recently the account was active. Before uploading, confirm the numbers are in the post-2018 ten-digit format — retired eleven-digit prefixes return nothing. Since Zalo penetration in Vietnam is already very high, put your budget into activity tiering rather than repeatedly re-running registration checks.
Can Zalo screening return gender and age?
Yes. The express lane offers combined gender and age screening, and the stable lane additionally returns the nickname. Zalo users typically supply gender and birthday at signup and use real names, so this data carries more weight in Vietnam than on most platforms and works well for age-banded outreach.
Express lane or stable lane for Zalo — which should I pick?
It depends on batch size and purpose. The express lane returns results quickly and suits a first coarse pass over lists in the hundreds of thousands. The stable lane is slower but steadier, better for a narrowed-down batch you're about to actually contact. A common approach is express for the coarse pass, stable for verification.
