How are you retrieving the service tags? From the vCenter (or host) GUI or from the ESXi command line?

Check if that serial number is of Chassis. This is known issue. Even in HP and Cisco, you will get this shown in vSphere web client and RVTools, the ESXI hosts shows the virtual serial number of chassis. Please use PowerCLI cmdlets or script something like Finding serial number of esxi hosts_powercli to get correct information.

This is a known issue and is scheduled to be fixed in November (tentative) patch release.

Using powerCLI and running "esxcli hardware platform get" or "esxcfg-info"  on the ESXi host will show the correct Serial Number of the blade.
