What Is a Minnesota MMB Supplier ID?

Last updated: August 24, 2026.

Bottom line: an MMB supplier ID is the State of Minnesota payment identity that MHCP uses for electronic funds transfer. For direct deposit, Minnesota says you need an active 10-digit supplier ID and a separate 3-digit location code from Minnesota Management and Budget. It is not your NPI, UMPI, or MHCP provider number.

If Minnesota Medicaid enrollment asks for an EFT vendor number or MMB supplier ID, the wording can make it sound like another clinical credential. It is not. The supplier record lives in Minnesota’s statewide financial system, while your provider enrollment lives with Minnesota Health Care Programs (MHCP). The two systems have to be connected before MHCP can send claim payments to the bank account on the supplier record.

This guide explains what the number means, how to determine your next step, what information to gather, and how to finish the MHCP handoff after MMB activates the record.

What Is an MMB Supplier ID?

Minnesota Management and Budget, or MMB, operates the Statewide Integrated Financial Tools system known as SWIFT. Organizations and individuals receiving state payments are represented in SWIFT as suppliers, vendors, or payees. MMB notes that “vendor,” “supplier,” and “SWIFT ID” all refer to the supplier ID in this context.

For an MHCP provider, that supplier identity tells the state where approved claim payments should go. Minnesota DHS says providers who want MHCP direct deposit must have:

• A 10-digit supplier ID, assigned by MMB.

• A 3-digit supplier location code, also tied to the MMB supplier record.

• Active banking information, connected to the supplier record and through its activation period.

A complete value may be displayed with a dash between the two pieces, but MPSE treats them as the EFT Vendor Number and EFT Vendor Location Code. Keep both pieces available.

What the Supplier ID Is Not

• It is not an NPI. An NPI identifies a health care provider in national transactions.

• It is not a UMPI. A UMPI is a Minnesota provider identifier used for certain providers who are not eligible for an NPI.

• It is not the MHCP enrollment or provider number. MMB assigns the supplier ID for state payments; DHS manages the MHCP enrollment record.

• It is not what establishes provider eligibility. The MPSE manual says the EFT Vendor Number field is optional. If it is blank, MHCP distributes claim payments by paper check instead of EFT.

The practical distinction: you can have an MHCP enrollment record without EFT, but you cannot receive MHCP direct deposit until the MMB supplier ID is active and connected to that enrollment record.

Do You Already Have a Supplier ID?

If the practice already has Supplier Portal credentials, sign in through the Minnesota Supplier Portal and review the supplier record. MMB says existing suppliers can use the portal to view payment details and maintain address and contact information.

If you do not have portal access or do not know whether the practice is already registered, do not create a duplicate record just to see what happens. Minnesota’s public instructions direct existing suppliers to request a user ID or contact MMB for supplier-record help; they do not describe an anonymous supplier-ID lookup.

• MMB EFT Helpline: 651-201-8106, Monday through Friday during posted support hours.

• MMB EFT Help Desk: [email protected].

Ask MMB whether the legal entity already has a supplier record, whether it is active for direct deposit, and how to recover or request portal access. Have the practice’s exact legal name and tax ID available for the conversation, but send sensitive information only through a channel MMB approves.

How to Register a Therapy Practice as a New Supplier

An LLC, professional corporation, or other business expecting payment should use the Supplier registration path. The Payee path is for an individual payee rather than a business, and the Bidder path is for bidding on state opportunities.

1. Confirm the entity that will be paid. For a group practice, this is normally the organization whose legal name, tax ID, and enrollment record will receive MHCP payment.

2. Gather the legal and payment information. MMB’s current supplier guide lists the FEIN or SSN, exact legal name, address, contact name, email, phone number, bank name, account type, routing number, and account number. Keep a current W-9 nearby to check the legal name and tax ID for consistency, although the current MMB guide does not list a W-9 upload in the seven registration steps.

3. Open the official portal. Use mn.gov/supplier, select Register for an Account, and choose Register as Supplier.

4. Enter the entity and TIN information. Use the same tax identity and legal name that belong on the MHCP enrollment record. MMB’s guide says SWIFT will stop a new registration when the same TIN already exists, which is another reason to resolve an uncertain existing record before starting over.

5. Complete the address and contact sections. Enter the primary address and a responsible practice contact. Add separate remittance or invoice addresses only when they are actually different.

6. Add the banking information for EFT. Select the EFT/bank option and carefully enter the bank name, account type, routing number, and account number. A transposed digit here can delay payments.

7. Review and submit. Accept the terms, submit the request, and save the Registration ID from the confirmation screen and email.

There Are Two Different Waiting Periods

Do not treat supplier registration approval and EFT activation as the same event.

• Supplier registration review: MMB’s current guide says Supplier registration typically takes about two days for review and activation and tells applicants to allow up to three days for approval.

• Banking activation for MHCP EFT: Minnesota DHS says it takes 10 business days after banking information is added before the supplier ID becomes active for direct deposit.

Wait through the 10-business-day banking period before notifying MHCP. If you are unsure whether the ID is active for direct deposit, DHS specifically tells providers to call MMB at 651-201-8106.

How to Connect the Active Supplier ID to MHCP

Getting the number from MMB does not automatically update the MHCP enrollment record. After the banking activation period, notify MHCP using one of the two official paths.

1. MPSE: Enter the active 10-digit ID in the EFT Vendor Number field and the 3-digit code in EFT Vendor Location Code under Enrollment Record Information. DHS says the location code is required whenever an EFT Vendor Number is present.

2. DHS-3725: Complete the EFT Supplier ID Notification form. For provider types other than personal care provider organizations and home- and community-based waiver providers, the form directs providers to fax it to MHCP Provider Eligibility and Compliance at 651-431-7462.

The federal tax ID or SSN on the MHCP submission must match the tax identity associated with the supplier record. DHS warns that a mismatch can delay payments.

Which Location Code Should You Use?

MMB says 001 is the usual 3-digit location code when the entity has only one address on file. If the supplier record has multiple addresses, confirm the correct location code with the MMB EFT Helpline before sending DHS-3725 or updating MPSE.

What to Send Your Biller or Credentialing Partner

If a billing or credentialing partner is handling the authorized MPSE or signed-form submission, send only what they need through a secure channel:

• the active 10-digit supplier ID

• the correct 3-digit supplier location code

• the legal name and tax-ID type used for the supplier record, without emailing a full SSN or bank account number

• confirmation that the 10-business-day banking period has passed

Do not send the Supplier Portal password, bank-login credentials, or an MFA code. And make the next step explicit: your partner should tell you whether they will enter the values in MPSE or prepare DHS-3725. Simply sending the numbers to a third party does not notify MHCP.

If your partner needs MPSE access, use individual delegated access instead of sharing an owner password. See our guide to giving Bomi individual MN-ITS and MPSE access.

Common Mistakes That Delay Minnesota Medicaid EFT

• Using an old direct portal hostname. Start from mn.gov/supplier so Minnesota can redirect you to the current Supplier Portal host.

• Creating a duplicate record. Call MMB when you suspect the legal entity or TIN may already be registered.

• Choosing Bidder instead of Supplier. A therapy practice registering to receive payment should use the Supplier path.

• Submitting to MHCP too early. DHS says the banking information needs 10 business days before the supplier ID becomes active.

• Leaving out the location code. MHCP needs both the 10-digit supplier ID and the 3-digit code for EFT.

• Assuming MMB automatically tells DHS. The provider still has to update MPSE or submit DHS-3725 after activation.

• Using mismatched tax information. Keep the legal name and FEIN or SSN consistent across the MMB supplier record and MHCP enrollment.

Where Bomi Fits

Bomi helps therapy practices separate the state payment setup from the Medicaid enrollment itself, identify which step is actually pending, and complete the MHCP handoff through an authorized path. We do not need your Supplier Portal password or bank login.

Frequently Asked Questions

What is an MMB supplier ID for Minnesota Medicaid?

It is the State of Minnesota payment identifier assigned by Minnesota Management and Budget. MHCP uses an active 10-digit supplier ID and 3-digit location code to connect approved claim payments to the banking information on the supplier record.

Is an MMB supplier ID the same as an NPI or UMPI?

No. An NPI or UMPI identifies the provider, while the MMB supplier ID identifies the person or organization receiving state payments. It is also different from the MHCP enrollment or provider number.

Can I enroll with MHCP without a supplier ID?

The MPSE manual says the EFT Vendor Number field is optional. If it is blank, MHCP distributes claim payments by paper check. An active supplier ID and location code are required when the provider wants MHCP payments by EFT or direct deposit.

How long does an MMB supplier ID take to become active?

MMB says Supplier registration typically takes about two days and tells applicants to allow up to three days for approval. Separately, Minnesota DHS says it takes 10 business days after banking information is added before the supplier ID becomes active for direct deposit.

How do I tell MHCP about the supplier ID?

After the banking activation period, enter the active 10-digit supplier ID and 3-digit location code in MPSE Enrollment Record Information, or submit the EFT Supplier ID Notification form DHS-3725 to MHCP Provider Eligibility and Compliance.

What if I do not know whether my practice already has one?

If you have Supplier Portal credentials, sign in and review the record. If you lack access or are unsure whether the legal entity is registered, contact the MMB EFT Helpline at 651-201-8106 or [email protected] before creating a new supplier registration.
