Why do I receive a “You don’t have access” error when I try to log in to the MyMCB portal?

This error usually means one of the following:

1. You are registered as a business user. At this time, the MyMCB portal is only available to personal users.
2. Some required personal information (such as your date of birth) is missing or incomplete in our records.

We aim to make the portal available to business users in the future.

If you are a personal user and cannot log in, please visit one of our branches once to update and complete your personal details. After your information has been updated, you will be able to access the MyMCB portal and manage your information online.

What are the requirements for a proof of address?

When changing your address, we ask you to submit a valid proof of address.

Accepted documents include:

A utility bill, bank statement, or government‑issued letter
A valid identification document that shows your current address

The document must:

Clearly show your full name and residential address
Include a date
Be no older than six (6) months
Be clear and readable, where the relevant information is not blurred

You may upload:

A PDF document (for example, one received by email)
A scanned copy of a paper document
A photo of the document

If you take a photo, please ensure there is sufficient lighting and that the entire page is visible and in focus.

Why do I receive email alerts from the bank, but the self‑service portal says no email address is on file?

Some bank services may currently use different email information. When you update or confirm your email address in the self‑service portal, it will be synchronized across our systems and used consistently going forward.

If you are receiving emails from us, your email address is already known to us. Updating it in the portal ensures everything is aligned and up to date.
