answers 402
Identify which carrier issued a tracking number using a deterministic, versioned signature set - prefixes, lengths, carrier check digits and UPU S10 structure - returning ranked candidates with the reasons each matched, the parsed S10 details and a rule-based (uncalibrated) confidence. No upstream call and no carrier account required. Use when: Which carrier is this tracking number from?
