What are the differences between confirmed and unconfirmed letters of credit?

Letter of credit is an irrevocable undertaking of the issuing bank to honour a complying presentation.

The beneficiary of the letter of credit must be ascertain that she/he will get the payment from the issuing bank as long as she/he comply with the terms of the credit.

From the beneficiary's perspective, complying presentation must be equal to payment, without any excuses. But in reality, sometimes things work differently.

For those instances, the beneficiary may seek another bank's payment undertaking added to the letter of credit, in addition to that of the issuing bank's.

The process is known as confirmation and the bank adding its confirmation to the credit is called as confirming bank.

If a letter of credit possesses a confirming bank's confirmation, then the credit becomes a confirmed letter of credit.

If a letter of credit reaches to the beneficiary with only issuing bank's payment undertaking, without confirmation added by another bank, then the credit becomes an unconfirmed letter of credit.
