Capabilities
What can GeekNums check with Number Filter?
Invalid Number Check
Invalid number checks give your numbers a basic status pass, filtering out empty and non-compliant numbers so you spend less time on useless data later.
Activity Filter
Activity filtering helps you pick out numbers with the target status, moving your data from "valid" to "better fits your business".
Power Status Check
A valid number isn't always reachable. Power status checks reveal a number's current state, helping you find data that meets your current business needs.
Do-not-disturb Check
Checks a number's current do-not-disturb status as an extra filtering signal. Combined with invalid, activity and power status checks, it lets you segment number data further.
Device Model Check
Device model checks retrieve device information for numbers to help classify your data. For users with large number lists, model information is a useful extra dimension for filtering and organization.

FAQ
Number filtering applies different check conditions to find qualifying data in large number lists. GeekNums currently offers invalid number checks, activity filtering, device model checks, power status checks and do-not-disturb checks.
An invalid number check is one specific type of number filtering, mainly used to remove empty and invalid numbers.
Number filtering is the broader concept: you can choose invalid, activity, device model, power status, do-not-disturb and other checks depending on your needs.
The device model check retrieves device model information for numbers, which you can use as an extra dimension for classification and filtering.
The power status check shows a number's current state, helping you filter numbers that meet specific status requirements.
The do-not-disturb check determines whether a number is currently in do-not-disturb status, adding an extra data dimension for filtering.
