ABCD Numbers

ABCD numbers contain a rising run of digits, such as 2345 or 6789. Customers can work the number out rather than memorise it, which makes these perfect for businesses.

Every ABCD number is a real UK pay-as-you-go SIM. Pay once, own it for life and move it to any network with a PAC code.

Prefer the run backwards? See DCBA numbers.
