Choose justified precision
Use an exact age only when it is known for the relevant time. Use boundaries for a supported range. Do not turn a visual estimate into a verified personal fact.
Check the boundaries
The lower limit should not exceed the upper limit. Do not enter an exact age that conflicts with the range. If it is unclear how the bot combines fields, check the form instructions before submitting.
Account for time
Age changes and a source record may be old. Note where the value came from and its date. A broad range can produce more ambiguous matches, so compare results with other details.
