The eight digits 86040805 identify an OPPO Reno6 Pro 5G. A phone whose IMEI starts with them is that model, whatever the seller wrote in the listing — the TAC is the manufacturer’s own allocation, not a lookup table someone typed by hand.

TAC / IMEI lookup resolves it and returns the specification sheet. For the lock state, use the $0.03
SIM lock check — a model lookup cannot tell you whether the handset is carrier locked.
What a TAC cannot tell you
Three things decide whether a device is worth buying, and none of them is in the TAC: whether it is carrier locked, whether it is blacklisted, and whether iCloud or MDM is on. Those are separate records against the full IMEI, and each costs a few cents to read.
- Carrier lock — the operator that owns the activation policy, from $0.03.
- Blacklist — GSMA and carrier registers, from $0.03.
- iCloud / MDM — the locks no unlock service can remove.
