What are key identifiers
Key identifiers are unique codes assigned to a device by the manufacturer. They are used to identify the device, not to describe its condition, ownership, or usage history.
In a basic IMEI or serial number check, the identifiers you see are usually the same ones you provided for the lookup.

Main identifiers you may see
IMEI
The IMEI (International Mobile Equipment Identity) is a unique identifier assigned to mobile devices. It is used to:
- identify the device model and generation
- distinguish one device from another
- link the device to manufacturer records
IMEI confirms which device is being checked, not its current state.
Serial Number
The serial number is another manufacturer-assigned identifier.
It is often used to:
It is often used to:
- track production batches
- support warranty and service records
- identify device variants
Some manufacturers rely more on serial numbers than IMEI for internal tracking.
IMEI vs Serial Number: key differences
- IMEI is commonly associated with mobile network identification
- Serial number is often tied to manufacturing and service records
Both identify the device, but they serve different technical purposes.
Having both identifiers does not mean “more data” - it means different reference points.

Why identifiers matter in a report
1. Identity confirmation
Identifiers confirm that the report corresponds to the exact device you intended to check.
2. Error detection
They help spot:
- typos in the entered identifier
- mismatches between identifier and device description
3. Reference consistency
Identifiers ensure that all other fields in the report are linked to the same device record.
What key identifiers do NOT tell you
Key identifiers do not provide information about:
- physical condition of the device
- lock or blacklist status
- ownership history
- location or tracking
They identify the device - they do not evaluate it.
Why identifiers usually do not change
IMEI and serial numbers are assigned during manufacturing and remain constant throughout the device’s lifecycle.
If a report shows:
If a report shows:
- only the identifier you entered
- no additional identifiers
This is a normal outcome for a basic check
Common misunderstandings
“Valid format means the device is clean”
A valid identifier format only confirms that the number is structured correctly.
“More identifiers mean a better report”
The usefulness of a report depends on available data sources, not on the number of identifiers shown.
“Missing identifiers mean a problem”
If an identifier is not displayed, it usually means it is not available from the data source, not that the device is problematic.
When to pay attention to identifiers
Review key identifiers carefully when:
- buying a used device
- comparing multiple listings
- checking high-value devices
- validating seller-provided information
They are the foundation of every IMEI-based check.
Summary
Key identifiers confirm which device is being checked. They help ensure accuracy and consistency, but they do not describe condition, status, or usability.
Understanding their role helps you read IMEI reports correctly and avoid incorrect assumptions.
