How do I check a Saint Laurent bag by number?

To check your Saint Laurent bag’s serial number, find the tag on the inside of the bag and flip it over. Saint Laurent serial numbers have 12 digits separated by a dot. Some bags will have “Made in Italy” present on the tag, but the words must be directly under the digits. If there is unequal sizing or spacing between the letters, or there’s no serial number at all, then you’re looking at a fake. On 1stDibs, you’ll find a collection of expertly-vetted Saint Laurent bags from some of the world’s top sellers.
