# Aware mass market identifiers

There are two AMM client identifiers used in the Qualcomm Aware ecosystem.
1. Aware serial number
2. Device serial number

## Aware serial number

Aware serial number (ASN) is the device serial number assigned by Qualcomm that is globally
        unique within the Qualcomm Aware ecosystem. The ASN is a 12-character string consisting of a
        3-letter prefix followed by 9-digit number which shall be auto incremented per device, for
        example `MMD000000001`, created by the Aware Cloud automatically for the
        device and does not require any specific action by customers.

Customers can use the ASN when identifying a particular device within Aware. Additionally,
        the ASN is needed when customers create support tickets with Qualcomm.

## Device serial number

Device serial number (DSN) is an identifier generated by the manufacturer and is not
        globally unique within the Qualcomm Aware ecosystem. The DSN can be a string up to 64 chars,
        for example `exId120515`.

DSN information is used to check what LaaS service(s) a particular customer device is
        entitled to and is a mandatory field in the REST API header when communicating with Qualcomm
        Aware Cloud.

Customers must provide the DSN along with the REST API HTTP Request. The Aware Cloud
        creates an ASN for the device, and this mapping is reported in the REST API HTTP response.
        Refer to [LaaS REST API](https://docs.qualcomm.com/doc/80-63441-4/topic/LaaS-REST-API.html) for details of the REST API.

There are no explicit requirements for a customer to register a device with Qualcomm
        (assuming that a valid Purchase Order for LaaS is fulfilled).
Note: It is the customer’s
          responsibility to ensure that the DSN reported to the Aware Cloud for each device is
          mapped to a unique device.
