FindMyFlag — Reverse Flag Search

Sources

The source stays the source

FindMyFlag is a search layer across existing flag material. It does not claim ownership of third-party reference images, and source attribution is kept wherever the original dataset provides it.

How images are used

FindMyFlag searches mathematical representations of flag images — not the images themselves.

During indexing, reference flag images are analyzed and converted into numerical embeddings: sets of numbers representing visual features, shapes, colours and relationships in the image. These numerical representations, together with available source metadata, form the searchable visual index.

When you upload an image, FindMyFlag creates the same kind of numerical representation and compares it mathematically with the representations in the index to find visually similar flags. Your uploaded search image is used only for this comparison and is not stored.

Metadata is only as complete as the source

Not every result contains the same metadata. If a country, original URL, title, date or another field is missing, that normally means the information was not present in the original dataset supplied to the index. FindMyFlag does not invent missing metadata just to fill an empty field.

Standalone FOTW images

Some images in the Flags of the World (FOTW) archive no longer have a linked source page in the available site snapshot. These images may come from pages or references that have since been removed, changed, or are no longer available.

FindMyFlag keeps these images searchable rather than discarding them, because they may still help identify a flag or show that the image once existed in the archive. When no additional source information is available, the result is marked as a Standalone FOTW image and further research may be needed elsewhere.

Ownership and attribution

Copyright and other rights in third-party source material remain with their respective owners, contributors and licensors. In particular, the flag images, research and documentation published by Flags of the World (FOTW) are the work of its contributors and image creators. FindMyFlag does not claim ownership of that material.

Where a usable FOTW source page exists, FindMyFlag links directly back to it so users can access the original context, source information and contributor or image-creator attribution maintained by FOTW.

Corrections and source contributions

If a source attribution is wrong, a link has moved, metadata can be improved, or you control material that should be added or removed, please contact FindMyFlag. Corrections are part of maintaining a useful research index.
