Hi @rafaelroseira ,

Try this,

> [@App Settings - Last Order Number to Total Number of Login](https://forum.adalo.com/t/app-settings-last-order-number-to-total-number-of-login/27158/6):
>
> New Customer ID that are 9 digits, separated by - Examples: 100-000-001 000-000-999 This can lead to easier searching to find customer.

This is actually a 1-record collection and can track the last number, in this case customer id number, so the next customer id will be increased by 1.

It will not duplicate.
