Your Tembo Cash ISA or Lifetime ISA account reference can be found in 'My Profile' under the Settings Tab.
Cash ISA reference looks like acc-xxxxxx-xxxx
Lifetime ISA reference looks like NUXXXXXXXXXX.
Note: your Tembo savings accounts don't come with a typical account number and sort code, this is because Tembo is not a bank, we are a savings provider.
If you want to make a deposit into your Tembo account you must do so by linking your bank account through the Tembo app, instead of making a payment direct from your bank account.
If you're having trouble adding money to your Tembo account through the Tembo app, try sending a smaller amount initially. If this works, then try sending a larger amount. Usually banks will automatically decline large payments to new payees as they view this as 'unusual' behaviour. Sending smaller payments first can help get around this.
