What does a GLS tracking number look like?
Most GLS parcel numbers are numeric and commonly run to 11, 12, or 14 digits, though some are shorter or longer. Because GLS operates as a group of national companies, formats vary by country: GLS Italy often uses two characters plus up to nine digits, and GLS France often uses an 8 character alphanumeric code or an 11 digit number.
