Yes – Optery definitely helps with this, but it’s not a silver bullet yet. If your phone number is already out there circulating, I would recommend: (a) Start by opting out of as many of the data brokers as you can, in particular the B2B contacts data brokers that are most likely the source of these unwanted phone calls like RocketReach, ContactOut, Clearbit, Hunter.io, LeadIQ, ZoomInfo, etc. Many of these data brokers Optery already covers, but others we are still in the process of adding to coverage. (b) You can use Optery to opt out of a large chunk of these data brokers (200+ as of today), but you might need to supplement that with your own effort until we can catch up to the rest of them. We’re constantly adding more data brokers to our list of covered every month. (c) Update your visibility settings on LinkedIn. A lot of information gets leaked out onto the web from LinkedIn, and in particular into the B2B contacts data brokers mentioned above: https://www.linkedin.com/help/linkedin/answer/a523134/visibility-of-your-email-address https://www.linkedin.com/help/linkedin/answer/a523134/visibi... (d) Do not include your phone number or title on your email signature – many of the B2B contacts data brokers have data co-ops where all of their millions of customers share contacts and they parse through the email signatures in your email (e) After you have done all of the above, and have reduced the footprint and presence of your phone number in these different places, change your phone number.
