Where Can I Find the CCV Security Code?
Some cards, for example MasterCard and Visa, have
a three-digit CCV printed on the signature strip on the
reverse side of the card. Other numbers may precede
AUTHORISED SIGNATURE
the CCV. The last three digits on the signature strip
4000 0012 3456 7890 123
are the CCV.
NOT VALID UNLESS SIGNED
Other cards, for example American Express, have
a four-digit CCV on the front of the card, above the
account number.
CCV
Some cards do not have a CCV.
Should I Save CCV Security Codes?
No. It is prohibited to store the CCV codes. They must remain secret. You must not write
them down or save them electronically. Doing so may lead to heavy penalties.
Manual Authorisations and CCV
If your terminal is not functioning at all, you can revert to a manual imprinter. When seeking
authorisation for a credit card transaction above the floor limit, be sure to provide the CCV
number if available.
