- proof of residence e.g. a utility bill;
- driver’s license;

Disputing transaction

When disputing transactions such as unauthorized charges, refunds, or payments put on hold, you will need to provide proof of transaction. This can be accessed by logging into your account and visiting the transaction history.

Identify the particular transaction and review the transaction details such as:
- the name of a merchant
- their address and contact information
- transaction date.
Take a screenshot of transaction details, which you will forward to the customer care representative if requested.

Card activation

When calling for card activation have the following in hand:
The card that needs to be activated. You may be required to provide the CVV code and expiry date or to take a photo of the card.
Phone or email address linked to the account/card. An activation code or pin may be sent to the phone or email address linked to your account

Alternatively, log into your online bank account or app and choose the activate card option. In most cases, you will be asked to provide the CVV code and expiry date. Some banks require you to take a photo of the card and upload it.

Account issues

For account login issues, provide your phone number or email address associated with the account on the login page. If calling customer service for such issues, you may also be required to verify that you are the account owner by providing the following information or documents:
- your account number;
- a brief history of recent transactions;
- government-issued ID;
- social security number.

In the case of a frozen or blocked account, find out the reason. The most common reasons banks freeze accounts include fraudulent activities such as issuing or cashing bad checks, and money laundering, IRS tax levy on unpaid taxes, or unpaid creditor debt.

In the case of unpaid debts, you will need to settle the debt and provide evidence. On the other hand, for fraudulent activities, you need to provide relevant documents to prove that the transactions were legitimate.
