What do allowlist and blocklist mean?

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.
