Dual-SIM devices have two IMEIs. ChromeOS devices require serial number, model, and `chromeOsAttestedDeviceId`. To find a device, a `DeviceIdentifier` object with required fields is used in the `partners.devices.findByIdentifier` API call.\n"],null,["# Identifiers\n\nA [`DeviceIdentifier`](/zero-touch/reference/reseller/rest/v1/partners.devices#DeviceIdentifier) encapsulates hardware IDs to identify a\nmanufactured device. This document explains how to work with identifiers in the\nzero-touch enrollment API.\n\nA `DeviceIdentifier` combines hardware metadata or IDs required to uniquely\nidentify a device.\n\nYour organization includes the device identifier values when uploading device\ndata through the portal or calling the API.\n| **Important:** a `DeviceIdentifier` represents a hardware device. It shouldn't be confused with `deviceId`, which represents a record in the API.\n\nRequired fields\n---------------\n\n### Android devices\n\nZero-touch enrollment typically identifies devices by the IMEI (or MEID)\ncellular modem IDs. To support devices without cellular modems, such as\ntablets, you can also identify devices using a different set of fields. The\nfollowing table shows the fields you can use for each type of device:\n\n| Identifier | Cellular | Wi‑Fi only | Notes |\n|----------------|----------|------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `hardware_id` | | | This field must be an IMEI or MEID number. Zero-touch enrollment validates the format of IMEI values when you pass them in API arguments. |\n| `hardware_id2` | | | This field must be a second IMEI or MEID number. Zero-touch enrollment validates the format of IMEI values when you pass them in API arguments. For information on devices with more than one cellular modem, see [Dual-SIM devices](#dual-sim). |\n| `serialNumber` | | | The manufacturer's serial number for the device. The serial number is case sensitive and is the same value that's returned from [`Build.getSerial()`](https://developer.android.com/reference/android/os/Build.html#getSerial()). |\n| `model` | | | The device model value must match the device's built-in value returned from [`Build.MODEL`](https://developer.android.com/reference/android/os/Build.html#MODEL). See the [model names](/zero-touch/resources/manufacturer-names#model-names) reference for a list of allowed values for each manufacturer. |\n| `manufacturer` | | | The `manufacturer` field value must match the device's built-in value returned from [`Build.MANUFACTURER`](https://developer.android.com/reference/android/os/Build.html#MANUFACTURER). See the [manufacturer names](/zero-touch/resources/manufacturer-names) reference for further information. |\n\nIf registering serial number you must also register manufacturer and model to\nensure zero-touch is able to detect the device.\n\n#### Dual-SIM devices\n\nA dual-SIM device includes two discrete modems and has two IMEI numbers. If\nregistering just one IMEI, prefer the numerically lowest IMEI number as\nzero-touch enrollment works more reliably with the lowest IMEI. To increase\nreliability you can additionally register the other IMEI, or the serial number,\nmanufacturer and model.\n\nTo display the second IMEI in the zero-touch portal:\n\n1. Go to the **Devices** tab.\n2. On the upper right corner, beside the **Add Device** button, click the three dots more_vert.\n3. Select **Customize table**.\n4. Select the checkbox for **IMEI2**.\n5. Click **Save**.\n\n### ChromeOS devices\n\nFor ChromeOS devices the set of required identifiers is the same for cellular\nand Wi-Fi only devices:\n\n| Identifier | Notes |\n|----------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `serialNumber` | The manufacturer's serial number for the device. |\n| `model` | The device model value must match the device's built-in value. See the [list of ChromeOS model values](/zero-touch/resources/chromeos-models) for reference. |\n| `chromeOsAttestedDeviceId` | The Attested Device ID. See the [list of compatible ChromeOS devices](https://support.google.com/chrome/a/answer/10130175?#identify_compatible&zippy=%2Cidentify-compatible-chrome-devices) for reference. |\n\nRefer to a device\n-----------------\n\nUse a `DeviceIdentifier` when finding or claiming devices. You need to include\nthe required fields specified for the type of device.\n\nThe following snippet shows an IMEI number used to search for a specific device\nby calling [`partners.devices.findByIdentifier`](/zero-touch/reference/reseller/rest/v1/partners.devices/findByIdentifier): \n\n### Java\n\n```java\n// Create a DeviceIdentifier.\nDeviceIdentifier deviceIdentifier = new DeviceIdentifier();\ndeviceIdentifier.setImei(\"123456789012347\");\n\n// Perform the search using the zero-touch enrollment API.\nFindDevicesByDeviceIdentifierRequest body = new FindDevicesByDeviceIdentifierRequest();\nbody.setLimit(1L);\nbody.setDeviceIdentifier(deviceIdentifier);\n\nFindDevicesByDeviceIdentifierResponse response = service\n .partners()\n .devices()\n .findByIdentifier(PARTNER_ID, body)\n .execute();\n```\n\n### .NET\n\n```c#\n// Create a DeviceIdentifier.\nvar deviceIdentifier = new DeviceIdentifier\n{\n Imei = \"123456789012347\"\n};\n\n// Perform the search using the zero-touch enrollment API.\nvar body = new FindDevicesByDeviceIdentifierRequest\n{\n Limit = 1,\n DeviceIdentifier = deviceIdentifier\n};\nvar response = service.Partners.Devices.FindByIdentifier(body, PartnerId).Execute();\n```\n\n### Python\n\n```python\n# Create a DeviceIdentifier.\ndevice_identifier = {'imei':'123456789012347'}\n\n# Perform the search using the zero-touch enrollment API.\nresponse = service.partners().devices().findByIdentifier(\n partnerId=PARTNER_ID, body={'deviceIdentifier':device_identifier, \\\n 'limit':1}).execute()\n```\n\nThe following snippet shows how to create a device identifier with a serial\nnumber: \n\n### Java\n\n```java\n// Create a device identifier to find a Wi-Fi-only device.\nDeviceIdentifier deviceIdentifier = new DeviceIdentifier();\ndeviceIdentifier.setManufacturer(\"Honeywell\");\ndeviceIdentifier.setModel(\"VM1A\");\ndeviceIdentifier.setSerialNumber(\"ABcd1235678\");\n```\n\n### .NET\n\n```c#\n// Create a device identifier to find a Wi-Fi-only device.\nvar deviceIdentifier = new DeviceIdentifier\n{\n Manufacturer = \"Honeywell\",\n Model = \"VM1A\",\n SerialNumber = \"ABcd1235678\"\n};\n```\n\n### Python\n\n```python\n# Create a device identifier to find a Wi-Fi-only device.\ndevice_identifier = {'manufacturer':'Honeywell', \\\n 'model':'VM1A', 'serialNumber':'ABcd1235678'}\n```\n\nLearn more\n----------\n\n- To learn more about hardware identifiers, see the [API reference documentation](/zero-touch/reference/reseller/rest/v1/partners.devices#DeviceIdentifier) for `DeviceIdentifier`.\n- To see a list of allowed manufacturer names and device models, review the [manufacturer names](/zero-touch/resources/manufacturer-names) reference.\n- To see a list of compatible ChromeOS devices, see the [ChromeOs Help Center](https://support.google.com/chrome/a/answer/10130175?#identify_compatible&zippy=%2Cidentify-compatible-chrome-devices)"]]
