IMEI and Serial Numbers are used for Android Enterprise and Esper Foundation. It allows you to upload up to 3000 devices at once using a CSV file.

Creating the CSV File
You can create a CSV file from scratch or use a template or spreadsheet program. All CSV file should follow these rules:
- The headers are "imei1, imei2, serialnumber" and shouldn’t be modified.
- Leave blank spaces between commas if additional identifiers aren’t needed. For example, you may just input serial numbers.
- All IMEI numbers need to be valid 15 digit numbers and can’t be duplicated.
- The file should end with a ".csv" file extension.
Example
imei1,imei2,serialnumber
12345678911121232,,
,43215678911121223,
,,SH32TW100000If you are using a spreadsheet program instead of a text editor, each field goes into three consecutive columns by row.
You’ll need to enter the exact IMEI numbers. If the digits are converted to a different format (for example, scientific notation), convert the digits to number format. See how to convert numbers to text in Microsoft Excel.
About Devices with Multiple IMEI Numbers
You can use either the IMEI or serial number for a particular device. As cellular devices will have both an IMEI and serial number, or in some cases have two IMEIs (dual SIM) and a serial number, the Esper system follows a particular order when processing a new device for IMEI-based provisioning:
- IMEI 1
- IMEI 2
- Serial Number
This means if you added IMEI 1 to Provisioning Template 1, IMEI 2 to Provisioning Template 2, and serial number to Provisioning Template 3, then Esper will provision the device according to Provisioning Template 1.
If you have already added an IMEI or serial number to a provisioning template and try to upload it again to another provisioning template, Esper will not use the uploaded CSV and will return a toast error message in the lower-left corner of your screen.
You can also upload a CSV or individually add IMEIs and Serial Numbers when editing a template.
Uploading the CSV
In the Epser console, go to Provisioning Methods and select Seamless Provisioning from the dropdown.
Add the device's blueprint.
Then, you can optionally select and add:
- a provisioning group
- an alias
- tags
Then, click on Bulk Upload.
Then, click on Upload New File and select the CSV.
After creating the CSV file, upload the IMEI / Serial Numbers to a template. Go to Provisioning Templates and click on the ellipsis (...)for the desired template. Then select the CSV file to upload.
Any time a CSV is uploaded, the previous IMEIs and Serial Numbers for that template will be deleted and replaced by the new additions from the CSV. This will not impact any devices that have already been provisioned.
Removing Serial Numbers
To remove serial numbers, go to Devices & Groups and search for the serial number. If a device has been onboarded with that serial number, its entry will appear in blue text. This means the device associated with this serial number has been provisioned. If you'd like to remove this device, see Removing Devices.
If a device hasn't been onboarded yet, its entry will appear in black text.
Click on the ellipsis (...) and choose Remove Registration. After removal, you may need to wait 15 minutes before adding the serial number to a new tenant.
