IQOS serial numbers rarely use the letter 'O'. They use the number zero (0). If your check fails, try substituting 'O' for '0' and vice versa.
While only PMI can run a full database check, the serial number structure reveals basic info.
| Code Section | Meaning | Example |
| :--- | :--- | :--- |
| First 3 letters | Manufacturing plant | PH (Philippines), CH (China), PL (Poland) |
| Next 1 digit | Year of manufacture (coded) | 3 = 2023, 4 = 2024 (varies by brand) |
| Next 1-2 digits | Month | 01 (Jan) to 12 (Dec) |
| Remaining digits | Unique unit ID | Random | iqos serial number check
