System Upgrade

Please check this page regularly for updates on affected services and important dates you should be aware of.

A Better Banking Experience Is Coming

We’re excited to take the next step in improving the technology that supports your everyday banking.

October 1–5, 2026, Post Office Credit Union of Maryland will upgrade its core banking system. This important upgrade will strengthen the systems behind your accounts and services, improve security and efficiency, and give us a stronger foundation for the future.

While much of the work will happen behind the scenes, some banking services will be temporarily unavailable or affected during the October 1–5 transition. We want you to feel prepared and confident throughout the process.

That’s why we’ve created this dedicated System Upgrade page. Here, you’ll find important dates, service information, FAQs, digital banking updates, instructions, and other details to help you prepare.

Please check back regularly as we get closer to October. We’ll continue to share important updates through email, statements, and other member communications.

We appreciate your patience and understanding as we make this important investment in your credit union. We’re excited about what’s ahead and look forward to bringing you an improved banking experience.
