post office accounts - credit card number?

[smilingalltheway]

if anyone has a basic post office account / card account

have a look at the numbers on that account, especially the card number

they have 16 digits.... which to me says it's a credit card number.... (and these cards don't use the visa symbol and cannot be used for credit the way is usually used, so why the 16 digits?)

is this the credit number to your NI number?

why would it be a credit card number?

just thought i'd post see if anyone has more info on this.
