Article summary
Before choosing an age from a customer form or a Zalo result, check whether the two records refer to the same date, definition, and person.
Example record
Last year's booking form shows 34.
This year's Zalo age-and-gender result shows 35.
Which value goes into the business sheet?
Keep both observations. Preserve 34 with the original form date. Save 35 alongside the date and source of the screening result. The numbers alone do not establish a conflict. The customer could have had a birthday in between. The form could have collected an age bracket that someone later replaced with a single value.
Review three details in order
Start with the date. The original entry describes the age at the time the form was filled out. If today's business process needs a current value, verify it as appropriate and keep the older entry in its own record.
Next, check the definition. Read the original question. Did it collect an age, a birth year, or a range? A result of 35 fits within a self-reported range of 30 to 39. Keep the range as a range. If the definition is unclear, flag it before using it in a report.
Finally, check who the row represents. Compare the complete phone number and original record reference. A shared family or department number, or a submission using an old number, can make two records appear to refer to the same person. A profile photo cannot resolve the identity or supply an age for a disputed row.
Show the coverage of the report
Use a confirmed source for the main summary and count missing, incompatible, and unverified rows separately. Suppose 90 of 100 records can be summarized on the same basis and the remaining 10 need review. Report the 90 usable rows and keep the pending count visible. If corrections arrive later, update only the affected records so the change in totals can be explained.
If age affects eligibility, follow your organization's established verification process. If you only need to know whether a phone number is registered on Zalo, use the separate registration task.[1]
