UkAccountNumber

On this page

A UK bank account number: eight digits, with any leading zeros kept.

Use it beside a UkSortCode. For the two together, use BankAccount.

Shape

One value, held as text in one set form, with no parts: 88837491.

Example

example
UkAccountNumber("66374958")

UkAccountNumber(raw) checks the text, and text that isn't one breaks the format rule.

text.parse(raw, as: UkAccountNumber) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as 6637495, 663749580 or 6637495A.

Good to know

  • It must have all eight digits, so keep any leading zeros.
  • == tells you whether two are the same. < and list.sort_by don't take it.
  • A field that holds one counts as personal data (financial), so you don't mark it yourself.

In JSON

A string, in a request, a response or json.write:

json
"66374958""88837491"

Details

Text form, storage, how it is shown, and operations

UkAccountNumber is in the group Money and banking, and has been in Jadpo since 0.1.0.

Text form

text.from writes one standard text form, the same form text.parse reads back: 66374958 and 88837491.

How it is stored

It is stored in one column named for the field, of type text. 88837491 is stored as '88837491'.

How it is shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Value Shown
66374958 66374958
88837491 88837491

Operations

It also takes text.parse, text.from, text.format, json.read, json.write and ==. How every standard type behaves says how they work.
