# Verification

## Overview
The Verification class provides methods for verifying various Paystack entities including bank accounts and card BINs. This helps you validate customer information before processing payments.
## Methods
### resolveAccount

```typescript TypeScript theme={null}
const result = await paystack.verification.resolveAccount({
account_number: "0123456789",
bank_code: "058"
});
if (result.data) {
console.log(result.data.data.account_name);
console.log(result.data.data.account_number);
}
```
```javascript JavaScript theme={null}
const result = await paystack.verification.resolveAccount({
account_number: "0123456789",
bank_code: "058"
});
if (result.data) {
console.log(result.data.data.account_name);
console.log(result.data.data.account_number);
}
```
#### Parameters
The bank account number you want to verify
The bank code of the bank where the account is held. You can get this from the [listBanks](/api-reference/miscellaneous#listbanks) method
#### Response
Indicates whether the request was successful
A message describing the result
The account details

if (result.data) {
console.log(result.data.data.verified);
console.log(result.data.data.verificationMessage);
}

account_name: "John Doe",
account_number: "0123456789",
account_type: "personal",

console.log(result.data.data.verificationMessage);
}

});
if (result.data) {
console.log(result.data.data.bank);
console.log(result.data.data.brand);
console.log(result.data.data.card_type);
console.log(result.data.data.country_name);
}
```
```javascript JavaScript theme={null}
const result = await paystack.verification.resolveCardBin({
card_bin: "539983"
});
if (result.data) {
console.log(result.data.data.bank);
console.log(result.data.data.brand);
console.log(result.data.data.card_type);
console.log(result.data.data.country_name);
}
```
#### Parameters
The first 6 digits of the card number
#### Response
Indicates whether the request was successful
A message describing the result
The card BIN details
The card BIN that was resolved
The card brand (e.g., "Visa", "Mastercard")

## Error Handling
All methods return a result object with `data` and `error` properties. Always check for errors:
```typescript theme={null}
const result = await paystack.verification.resolveAccount({
account_number: "0123456789",
bank_code: "058"
});
if (result.error) {
console.error('Verification failed:', result.error.flatten());
} else if (result.data) {
console.log('Account name:', result.data.data.account_name);
}
```
