Do my Savings Jars have their own account number?
Savings Jars do not have their own account numbers - your Monzo account will only have one account number for the main debit card account. Savings Jars also do not have their own card number, and you are unable to make transactions directly from a Savings Jar.
To add money to a Savings Jar, first deposit the money into your Monzo debit card account and then transfer it into your Savings Jar 💵 Then, when you need access to that money - you can transfer money directly from the Jar to your main account at any time, as often as you need.
