The number is currently on switch number SNANTXTS1MD. While 8302151042 was originally issued with the info above, the owner of the phone number (830) 215-1042 may have transferred it through a process called porting.
Caller name: Put Vets First
Caller type: Scammer/Fraudster
Same name (Stan) and call center background as received from other numbers (712-220-8031, 617-833-4891) one in which he identified that he was calling for Put Vets First. It seems to exist but don't trust a charity that uses spoofed numbers for donations. I consider it a scam.
