text origin

[Flipporus]

In reviewing my bill I am seeing texts on one of are family phones that have this protocol I am masking the last four digits..

000-088-BBBB

000-003-BBBB

000-006-BBBB

Can anyone help me as to the possible source of these texts. Is it a social media site,skype or in some quick research I did there was a mention of a spoof service or interim party service to mask the number. Thanks so much in advance for your help!
