How can an authentic Gucci handbag be identified?

Distinguishing the authenticity of a Gucci handbag is a skill, as counterfeit goods are becoming increasingly sophisticated. A genuine Gucci bag's inner label features "GUCCI" printed on the top and "Made in Italy" printed on the bottom, in neat fonts. The reverse side of the inner label features two rows of numbers (the top row is the style number, the bottom is the supplier number), neatly engraved and evenly spaced. Counterfeit goods often have blurred printing or irregularly spaced numbers.
