Number overview
0800-777-2224 is a toll-free number (the 0800 prefix). Multiple directories carry user reports describing used-goods purchase sales calls in the name of "Cowl" (as of 2026-08-03). On Telnavi, 135 users have contributed information, classifying it as used-goods purchase calls with a fee warning. This site previously described the number as real-estate sales; the confirmed reports concern used-goods purchase sales, so we corrected the description.
Reported behavior
- Callers claiming to be "Cowl" offer to buy unwanted goods or books
- Some reports describe bursts of repeated calls in a short period
For phone-initiated in-home purchases, the Act on Specified Commercial Transactions prohibits demands to buy items other than those you requested (such as precious metals). If you did not request a purchase, we recommend not agreeing to a visit.
How to handle this call
If not interested, refuse clearly and hang up. Block the number if the calls persist, and consult the Consumer Hotline (188) about aggressive solicitation.
