Verdict

The call

The clearest difference is price: UN Number at Free against Cargo Decoder Plus's $1.99. UN Number also leads on rating (4.7 vs 4.3) and ratings volume (54 vs 6). Cargo Decoder Plus's advantage is in-app purchases (none vs 5) and update cadence (monthly vs every 3 months). On ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

UN Number holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: UN Number has 54 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 63% of UN Number's written reviews are positive against 71% of Cargo Decoder Plus's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

UN Number ships an update every 3 months, Cargo Decoder Plus monthly. The most recent releases landed on September 22, 2026 and September 14, 2026 respectively.
