How to read a UPS tracking number

Most tracking numbers combine a service or product prefix, a serial number that uniquely identifies your shipment, and (for many carriers) a final check digit used to catch typos. International postal items often follow the UPU S10 standard — two letters, nine digits and a two-letter country code, e.g. RR123456789GB. If a number doesn’t match any known UPS pattern, it may belong to a different carrier or have been entered incorrectly.
