Spam protection
Stay off Spam Likely.
Number Guard watches your caller IDs every weekday. Numbers that look risky rest before they burn, and flagged numbers can be swapped automatically.

Number Guard
Know which numbers are flagged.
Turn on Number Guard for a US or Canadian number and it is checked every weekday against carrier and app spam databases and FTC complaint records.
Three health states
Healthy, Likely Spam or Spam, from several sources combined, with the pickup rate of the last 50 calls.
Per number, or all at once
Switch it on for one number, or enable it across your whole pool.
Swap from the list
Any number that is not healthy can be swapped for a matching one in a click.
| Phone Number | Health | Number Guard |
|---|---|---|
+1 (512) 555-0101 Austin, TX | Healthy 31% pickups (last 50 calls) | On |
+1 (737) 555-0134 Austin, TX | Likely Spam Checked Nov 4 | On |
+1 (512) 555-0177 Austin, TX | Spam Checked Nov 4 | On |
+1 (214) 555-0158 Dallas, TX | Healthy 27% pickups (last 50 calls) | Off |
Resting and auto-swap
Rest numbers before they burn.
Lead Hero takes numbers out of rotation when they look risky, and skips them when it picks a caller ID.
Likely spam rests for 7 days
Numbers flagged as likely spam leave rotation for a week.
Heavy use and low pickups rest too
Every number rests after its daily call limit or a run of low pickups, with or without Number Guard.
Auto-swap flagged numbers
Switch it on and a number flagged as spam is released and replaced, in the same area code when one is available.
