The above number came to me on a text.  The SMS identified no organization of individual.  It told me to reply with "help" or "stop," there will be recurring messages, and that rates may apply.  It sounds suspicious.  A search on google gave me nothing.  I am expecting a call from a health care organization.  There is no way for me to identify this caller or the purpose.  This number needs clarification.  I know not where to find such.

Came as text. Couldn’t get info on phone number.  Text said I had appointment with a doc. Didn’t say what doc or what time. It was very cryptic that way. Must be a text with a virus or some sort of scam.

Received a text saying to reply with Help or Stop, that I will receive recurring messages, and rates will apply. It did not identify the sender.

Forward unwanted spam/scam texts to 7726 (SPAM) and let your phone service provider deal with them.
That number was set up by the phone companies to combat spam/scam texts and they can shutdown offending phone numbers.
Never reply with "STOP", scammers will not honor the request (they have no honor to begin with) and it only verifies that they have texted to a valid number with a person who reads their texts.  It will not STOP the texts and may actually make them more frequent.
Never click on a link in such a text as it may cause malware to be inserted on your phone, and even if it does not, just as with replying "STOP" the scammers will know they reached a valid number.
Do not repost any links included in the text message to public sites such as this one.  It may subject others to malware if they click on it or, in some cases, it may reveal personal information posted on the target site of the link.  Links that are a domain followed by a string of characters and digits (e.g., "somedomain.com/AbC1d34q") are specific to the text recipient.  If the link is followed, the sender will know and assume the intended recipient clicked on it, which may lead to more texts being sent.
