Your Compiled Data Resource. 800-701-6531 Alesco is a marketing data broker; consumers can ask to be removed by emailing info@alescodata.com or calling (800) 701-6531 (a CCPA line, (877) 652-5002, is also listed). The policy also references a "Do Not Sell My Personal Information" link on its site, but the exact URL isn't given in the text. Include your full name and complete mailing address (city, state, ZIP) — Alesco says it denies requests it can't match to a record. Its own reported statistics claim a mean turnaround of about 2 days, though no formal response window is promised; since data is recompiled from public records, plan to re-check periodically.
