The EAN-13 standard is pretty close to what you need, giving single-digit error detection (tho not correction), and you can shorten it to the last 5 or 6 digits. As the last digit is the checksum, this gives you 4 or 5 digits of precision.
Back at my earlier workplace we used EAN-13s as product serial numbers. Generally in customer service we used the last 5 digits, with the leading ones being implied by product model.
