Once you have submitted your update request on the Digital Stable, we notify the relevant passport issuing organisation (PIO) on your behalf.
Once your PIO receives the update request, they have 15 days to review and update the CED with your changes (unless they have a valid reason why this cannot be achieved in this timeframe).
During this time they may need to contact you to;
Ask you for further documentation
Ask to see your equine's paper passport
Charge you to make the changes
Many PIOs explain their procedures policies and charges on their websites. A list o PIO's can be found in the following link;
