Unlike other marketplaces, Swappa runs device background checks on listings before they go live to make sure that devices aren’t blocklisted or reported lost or stolen.

• Allowlist (formerly referred to as whitelist): An allowlisted ESN/IMEI has been reported clean and ready for activation according to the GSMA global registry. An allowlisted device can be sold on Swappa.
• Blocklist (formerly referred to as blacklist): A blocklisted ESN/IMEI has been reported lost or stolen with the GSMA global registry. A blocklisted device cannot be sold on Swappa.
