Where to find the code
Inspect the inner band, clasp, bail or post under magnification. Enter only what you can read, and leave unknown details unselected.
How to read the result
Compare TIFFANY & CO. or T & CO. with metal marks such as 925, Au750 and Pt950. Elsa Peretti or Paloma Picasso signatures are collection details, not date codes. Marking styles vary by period and market.

Does a matching code mean the item is authentic?
This checker is a free code-matching tool only. It does not authenticate an item or provide an authentication verdict. Matching codes can appear on counterfeit items. We recommend LegitApp Authentication for an expert review of the item itself.

What if my code is missing or not recognised?
Recheck the characters and the type of marking. Vintage pieces, transition-era labels and newer layouts may fall outside this reference. Missing or unmatched codes do not establish that an item is counterfeit.
