Addendum. Googled the number and all I got back was from a site called WWW.NEW-NPAC.ORG, with a file containing the following:
L. Padmanabhan

<address> La Habra, CA 90633-044
<vox> 310 694-7576
<fax> UNKNOWN

Don't know if there is any connection to the text message I received or even how old the file is.
