Proxy number usage

You can use a proxy number instead of card ID in many cases.

A proxy number can be printed on the card envelope as a nonsensitive unique identifier of the card and can be used to activate the plastic card once received from the cardholder instead of PAN, CVV and expiration date. There are two reasons why not to use the card ID for card activation:

• it is too long (32 characters)

• it has a very specific format that may not fit with customer requirements.

The power of the Proxy number is the flexibility that NymCard offers to the customer to define the length and the format. For example, one client asked for 9 digits proxy number that does not start with 0. We are open to any other format as well.
