A Card Protection Agency (CPA) is a business that provides cardholders with a card number registration service. In the event that a card is lost or stolen, the cardholder can contact the CPA who will, on their behalf, advise the card issuer so that a 'stop' can be placed against that card number.  CPAs may also provide a registration service for a wide range of other personal items and documents.

On behalf of its Members APACS operates a Card Protection Agency Accreditation Scheme. The primary aim of the Scheme is to protect the interests of the consumer by ensuring that organisations seeking accreditation meet minimum-security requirements for the safe storage, processing and handling of valuable cardholder data.

The Card Protection Agency Accreditation Scheme has been in operation since 1998 and the APACS accredited CPAs are:
