About MaskOff
Blocked calls should not leave you guessing
MaskOff was built to give people useful information at the moment a caller chooses not to show their number.
US-based and focused on blocked-call identification since 2023
MaskOff is built in the United States by Moff Technologies LLC. Identifying and documenting unwanted calls is not one feature among many—it is what we do.
A focused product
We reveal the number behind incoming blocked calls on supported mobile lines, keep a call history, and include call recording with every subscription.
Clear limits matter
Some mobile plans are not compatible, and callers can fake the number shown on your screen. We would rather explain those limits plainly than make a promise the product cannot keep.
Try MaskOff for 3 days
The app will check your carrier and guide your setup.
