IMEI Check for Business BYOD: How IT Teams Verify Employee Devices

5 min readUpdated 6/1/2025

IMEI Verification for Business BYOD Programs

BYOD (Bring Your Own Device) programs allow employees to use personal phones for work. For IT departments, IMEI verification is a critical step in onboarding devices to corporate networks, MDM systems, and security policies. This guide covers how to implement IMEI-based device verification in a business context.

Why Businesses Need IMEI Verification for BYOD

  • Security compliance: Blacklisted or compromised devices on corporate Wi-Fi or VPN represent security risks — stolen phones may have malware installed
  • MDM enrollment: IMEI is the primary identifier used by MDM systems (Jamf, Intune, VMware Workspace ONE) to track and manage devices
  • Expense management: Verify that devices claimed for corporate reimbursement are genuine, not cloned or counterfeit
  • Insurance: Corporate device insurance often requires IMEI registration for each enrolled device

IMEI Data Points Relevant for IT Teams

  • Device model and OS version compatibility: TAC-based IMEI check confirms exact model and supported OS versions — required for MDM profile compatibility
  • Carrier lock status: Affects whether the device can access international roaming for travelling employees
  • Blacklist status: Flags stolen or compromised devices before they join the corporate network
  • MDM/DEP enrollment status: Verify whether a device is already enrolled in another organization's MDM before corporate enrollment

Bulk IMEI Verification for IT Teams

For large BYOD programs with hundreds of devices, manual IMEI checks are impractical. IMEI Check Pro's bulk verification plan allows IT teams to submit IMEI lists via API or batch upload for automated checking. Contact the IMEI Check Pro enterprise team for bulk pricing.

IMEI Registration in MDM Systems

When enrolling a device in MDM (Microsoft Intune, Jamf Pro, etc.), the IMEI is used as the primary device identifier. Best practices:

  1. Collect IMEI from employee during BYOD agreement signing (have them dial *#06# and photograph the screen)
  2. Run a verification check to confirm the IMEI matches the device model they've declared
  3. Record the IMEI in your asset management system alongside employee name and enrollment date
  4. Set up automated alerts for when enrolled IMEIs appear on carrier blacklists

IMEI Policy for Departing Employees

When an employee leaves the company, their BYOD device should be removed from corporate MDM. Document the IMEI offboarding in your system. If the employee's phone was on a corporate plan (corporate-liable), confirm the device is returned or that the carrier account and IMEI ownership are properly transferred or cancelled to prevent the carrier from eventually blacklisting an IMEI that's now in use by someone else.
