Sentinel Photo Guidelines

Posted in Communications General Rules Uncategorized

Updated rules and guidelines for the photo which must be supplied to sponsors in order to obtain a Sentinel card have now been added to the website. This applies to those applying for new or replacement cards only; those with current cards do not need to take any action.

The guidelines can be found at:

The quality and content of this image is extremely important as, if it does not meet the required standard, card production may be delayed or a card rejected at a work site.

The guidelines are based on those issued by the UK Passport Office and relate only to digital photos as paper photos are not accepted for Sentinel.
