major marketplaces recognize the Device History Report
Every passing device ships with a signed, immutable Device History Report: graded, carrier-cleared, and blacklist-clean. Most major marketplaces recognize the DHR, so listings carry the credential downstream buyers already trust.
Battery health, lock status, repair history, and cosmetic grade are captured in a single pass, alongside IMEI history, blacklist status, and carrier-lock status. The result is a consistent, auditable grade on every unit you sell.
A standardized credential on each device sets clear condition expectations for buyers, reducing disputes and returns and protecting your standing on the marketplaces you sell through.
The Device Integrity Check confirms IMEI, storage, color, and country straight from the device — so what you bought is what you list, before it enters your inventory.
The 80+ point pass runs automatically: battery health read from the device's own settings, OEM parts authentication, boosted-battery detection, lock and blacklist status. Objective results, not an operator's judgment call.
Every passing device earns a signed, immutable Device History Report, the credential most major marketplaces recognize.
The two-way API syncs results to your systems in real time, so certified devices move straight from the test station to marketplace-ready inventory.
Yes. Most major marketplaces recognize the Phonecheck Device History Report.
Returns come from mismatched expectations. Phonecheck's diagnostics are automated and objective — the battery reading is the exact value from the device's own settings, and OEM parts authentication catches non-genuine screens, batteries, and cameras before a buyer does. A verified condition report on every listing means fewer disputes, fewer RMAs, and fewer chargebacks.
Phonecheck's two-way API syncs test results, grades, and certification data to your systems in real time and returns the next step to perform, so results flow into your listing workflow without manual re-entry.
