How to Run This Check
- 1
Match the phone and IMEI
Dial *#06# and compare the IMEI with Settings, the box, invoice, and seller listing. Check IMEI 1 and IMEI 2 separately on dual-SIM phones when network status matters.
- 2
Check the relevant risk
Use the free result for available identity details. Choose a separate report only when it explicitly lists US blacklist, carrier, SIM-lock, or other status fields you need.

Confirm with the carrier
Use the intended carrier’s official BYOD checker and ask the original carrier about unlock eligibility, financing, or account restrictions before payment.
US Used-Phone Buying Checklist
An IMEI result is one part of the purchase decision. Complete these checks before money changes hands.
Blacklist status
A current clean result means the selected source found no flag at that time; it cannot prevent a later lost, stolen, fraud, insurance, or non-payment report.
Carrier or SIM lock
Confirm whether the phone is tied to its original carrier. On iPhone, also review Settings > General > About > Carrier Lock.
BYOD compatibility
Enter the IMEI in the carrier you plan to use. An unlocked phone can still be incompatible with a network, band, eSIM setup, or carrier allowlist.
Activation Lock or account lock
For iPhone, require Find My removal and complete setup after an erase. For Android, confirm Google FRP and manufacturer accounts are removed before payment.
MDM and organization enrollment
Check for Apple Remote Management, Android enterprise enrollment, school or company profiles, and seller evidence that the device was released by the organization.
Warranty and device history
Use manufacturer coverage sources or a report that explicitly lists warranty, replacement, repair or history fields. A warranty result does not prove ownership or physical condition.
Finance and ownership evidence
An IMEI report cannot prove the seller owns the phone or that every installment is paid. Ask for an original receipt, payoff evidence, and a written bill of sale containing the IMEI.
US Carrier and Prepaid Brand IMEI Checks
Use the original selling carrier for unlock questions and the intended carrier for compatibility. The names below cover major national, prepaid, cable, digital, and legacy carrier search intent without treating every brand as a separate network.
| Carrier or brand | Used-phone risk to check | Best next step |
|---|---|---|
| AT&T | Carrier lock, installment payoff, lost/stolen or fraud flag | Use AT&T Device Unlock for eligibility and your intended carrier’s BYOD checker for compatibility. |
| T-Mobile | Device lock status, payment balance, blocked IMEI | Check unlock status in the T-Mobile account or T-Life app and confirm compatibility separately. |
| Verizon | Device lock, blacklist and BYOD compatibility | Use Verizon’s official compatibility checker and confirm any unexpected lock with Verizon Support. |
| Cricket Wireless | Cricket device lock and service-history requirement | Confirm eligibility through Cricket’s official unlock policy or support; AT&T eligibility rules are not a substitute. |
| Metro by T-Mobile (MetroPCS) | Metro-specific lock policy and activation history | Contact Metro or use its official policy. T-Mobile does not process Metro or legacy MetroPCS unlocks. |
| Spectrum Mobile | Unlock status and Spectrum BYOD eligibility | Run Spectrum’s official IMEI compatibility check and ask Spectrum Mobile about a Spectrum-sold device. |
| Xfinity Mobile / NOW Mobile | Account standing, payoff, activation period and compatibility | Use Xfinity’s unlock support and BYOD flow; do not rely only on the underlying network name. |
| Visible | Visible lock period, account history and compatibility | Check the purchase date against Visible’s current policy because requirements changed for devices bought in 2026. |
| Boost Mobile | Prepaid versus postpaid unlock eligibility | Use Boost’s current unlocking policy; the timing differs by plan type and financing status. |
| Mint Mobile | Mint-sold device lock and T-Mobile-network compatibility | Check Mint’s own device-unlock policy and verify the exact model in its compatibility flow. |
| Google Fi Wireless | Unlocked status, model and eSIM compatibility | Phones sold by Google Fi are described as unlocked; use Google Fi’s official compatibility checker for another phone. |
| Straight Talk | Brand-specific unlock eligibility and activation record | Use Straight Talk’s official unlocking policy and BYOD compatibility flow. |
| Tracfone | Unlock eligibility, activation and device origin | Use Tracfone’s official policy; do not assume every Tracfone-family brand has identical handling. |
| Total Wireless | Total Wireless device lock and compatibility | Confirm through Total Wireless support or its official BYOD checker. |
| Consumer Cellular | Unlocked status and supported-device compatibility | Confirm the IMEI directly with Consumer Cellular before moving a used phone to the service. |
| US Mobile | Device unlock plus compatibility with the selected US Mobile network option | Use US Mobile’s compatibility guidance and select the network only after verifying the exact device model. |
| UScellular (transitioning) | Legacy device/account status during the T-Mobile transition | Use the current migration or support path shown for the account; the UScellular brand is transitioning in phases. |
| Sprint (legacy) | Legacy Sprint lock, account and device records | Treat Sprint as legacy T-Mobile intent and contact T-Mobile for the current support path. |
Frequently Asked Questions
What should I check before buying a used phone in the USA?
Match the IMEI to the device, check blacklist and carrier-lock status using the report that explicitly lists those fields, confirm BYOD compatibility with your intended carrier, and keep the seller receipt and messages. These checks answer different questions and none proves legal ownership by itself.
Does one IMEI result guarantee a phone works on every US carrier?
No. A clean blacklist result, an unlocked status, and carrier compatibility are separate. Run the intended carrier’s official BYOD or compatibility check before switching service.
Can I check Cricket, Metro, Spectrum, Visible, Boost, or other prepaid carrier phones?
Yes, you can identify the device by IMEI and use a report that explicitly includes the carrier or blacklist field you need. Unlock eligibility must still be confirmed with the carrier brand that originally sold or locked the phone.
What happened to Sprint and MetroPCS?
Sprint is legacy search intent following its merger and network integration with T-Mobile. MetroPCS is now Metro by T-Mobile, but Metro maintains its own device-unlock policy and support path.
