MT103 is a message type used for international customer transfers. This document confirms that the bank has received instructions to send money to a specific recipient.

An MT103 contains:

• sender details;
• recipient information;
• beneficiary account number;
• transfer amount and currency;
• payment purpose;
• fee information.

This is why MT103 is considered the primary proof of an international payment.

After the banking system transitioned to the ISO 20022 standard in 2025, the technical equivalent of MT103 became the pacs.008 format. However, most banks still commonly refer to it as MT103.

In 2026, international transfers have become technologically more complex. A single payment may pass through several correspondent banks and additional security checks.

According to international payment analytics, around 11–14% of cross-border transfers are delayed due to compliance and intermediary reviews.

In high-risk industries, this percentage is even higher.

That is why the existence of an MT202 does not mean that the funds are already available to the recipient.

Today, a crucial role in tracking international transfers is played by the UETR (Unique End-to-End Transaction Reference).

This is a unique 36-character code that follows the payment throughout its entire journey.

UETR allows businesses to:

• quickly determine the location of a transfer;
• identify at which stage a delay occurred;
• accelerate payment tracing through banks.

If an international transfer is delayed, businesses should request not only the MT103 but also the UETR.

In 2026, understanding the differences between MT103 and MT202 has become essential for any business working with international transfers.

It is important to remember:

• MT103 confirms a customer payment;
• MT202 reflects only interbank movement of funds;
• the existence of MT202 does not mean the money has reached the account;
• UETR helps quickly track transfers.

Despite the banking industry’s transition to ISO 20022 and the introduction of new formats such as pacs.008 and pacs.009, the core principles of international settlements remain the same.

Companies that understand how international payments work resolve transfer issues faster, reduce financial risks, and manage cash flow more effectively.

As global payments become increasingly complex, transparency, speed, and control are becoming the foundation of stable international business operations.
