Pros
- USPS FIM C is accepted by United States sorting automation.
- Lengths and check digits validate instantly with the exact rule named.

- Wrong lengths or missing check digits are rejected instead of printed.
- Low contrast or tight quiet zones fail high-speed sorters first.
- Screenshots prove encoding, not sorter-grade print quality.
Form requirements
- Enter fimc.
- Fixed postal mark; no reader self-check is available.
- Preview and downloads stay withheld until local verification passes where a reader exists.
