Didn't recognize #, but the space pushing the city & state info ( "YORK PA", in this case) to the edges of the screen is a "tell" that it's likely spam. And was flagged as such on another report site (apparently a solar power spam call).

No message left by "NEEDMORE PA" even though supposedly call went to voicemail. 7th call from this same caller ID (same area code & exchange, too). Guessing spam (another site had flagged # as being a solar power scam call).

A legit caller would have left a message. Of course, a legit caller wouldn't hide behind a generic (so-called) ID like "HUNTINGTON PA" either. And NO (legit) hits for # on Google! Clearly some sort of spam....

No connection between the caller ID: "SUPPLEMENT CARE" and this # as far as I've been able to determine. Got a similar call yesterday from "MEDI SERVICES" -- only they are NOT in the 412 area code! Guessing it's the same scammers because only the last 4 digits were diffferent....

Call came in ~9:30 AM. Didn't recognize # OR the caller ID: "NTDS". Picked & hung up at once as a precaution. No useful info about name on Google. None at ALL about it in conjunction with #. But DID find at least 7 sites like this which already had negative reports about #!

Caller ID just said "CARNEGIE PA" (yes, with space in the middle pushing the text to the edges of the screen). Some woman named "Julia" asked for me by (first) name but hung up when my husband asked her to leave a message. Suspect spam of some sort....

Caller ID said "MEDI SERVICES". Apparently a real business but this is NOT their #. They are in MA & would NOT be calling from a PA area code! Suspect spam using a spoofed caller ID.

No message left by "Name Unavailable" even though it went to voicemail. Tried calling back on a "safe" phone & got the "We do not recognize" this #" message. Well I don't recognize YOUR # and mostly neither does Google!
