Zalo number-checking FAQ
What is a Zalo Number Checker?
It processes an existing number list and returns structured results for the checks supported by this page: Registration check, Activity check, Gender & age. Use the output for list cleaning, segmentation and review.
Which Zalo checks are currently supported?
AppShai currently supports Registration check, Activity check, Gender & age for Zalo. Available fields and task status are confirmed on the live task page.
Is a Zalo registration check the same as phone-number validation?
No. A platform registration check looks for an account on the selected service. Phone-number validation checks the number itself. A valid number may still be unregistered on the platform.
Should I check registration or activity first?
Registration is usually the first step. Run activity or profile checks only on the records that remain relevant to reduce unnecessary processing.
How should I prepare the input file?
Use a TXT file with one phone number per line. Keep the original value, normalize country codes and formatting, remove obvious duplicates, and validate a small batch before a larger run.
How should I read the Zalo reference rates?
Current volume reference rates are Registration check: 14 credits / 10K numbers; Activity check: 30 credits / 10K numbers; Gender & age: 35 credits / 10K numbers. Credits are purchased with USDT; available fields, task status and final credit deduction are confirmed in the signed-in dashboard or with official support.
Can check results be used as marketing consent?
No. Results help organize a list and do not show that a person agreed to receive messages. You remain responsible for the source of the data, lawful processing, opt-out handling and applicable platform rules.
