Finding a IMEI number from a previously used phone
Around the middle of 2021 I bought a Note 9 and used that with my AT&T prepaid plan. Last year that phone was stolen and I found the phone but, I can't prove I purchased it without the IMEI number and I have no way of getting it. Even the company on Amazon I bought it from says they didn't record it. Does AT&T have the IMEI number from my old device?
