What the code means
A supplier of a personal emergency response system (PERS), which is an electronic device that enables a patient to receive emergency assistance when needed. The PERS is one of two different methodologies of notification: (1) where the patient summons emergency assistance themselves directly through the device or (2) emergency assistance is summoned through secure activation by the caretaker/guardian, which sends the device location to emergency responders.
Definition quoted verbatim from the NUCC Health Care Provider Taxonomy code set, version 25.1. Not paraphrased.
Where they are
Counted by practice location, not by mailing address or by licence state. A provider practising across a state line is counted where they practise.

Who registers under this code
25 of these are people and 508 are organisations, so 95% of the code is businesses rather than clinicians. Half of them had registered by 2014, and 111 registered in the last five years, 21% of the current population.
That is close to the pace of the registry as a whole.
Where the practices are
By practice-location city. City counts are noisier than state counts, because a large employer files one address for many providers.

Looking up a specific provider
These counts come from the monthly NPPES file. To check one provider, use their NPI: the lookup reads the live registry and shows whether the identifier is still active, which the monthly file cannot tell you about the last few weeks.
