Where can I find my Modern E-filing Number (MEF)?

[Anonymous_]

You must be thinking of some other number.

See https://www.irs.gov/e-file-providers/modernized-e-file-overview

To get your MeF Submission ID you have to call TurboTax support. Go to the following link for instructions to get a phone number to call, during the hours that support is open. The hours are shown at the link.

What is the TurboTax phone number?

If they don't recognize the term Submission ID, tell them it's the "DCN / MeF Submission ID."

Wild guess---are you really asking about the ID.me   for monthly child tax credit payments????

Q K2. How do I authenticate my identity? (added June 22, 2021)

A2. If you are a new user, you must create an ID.me account at the IRS and verify your identity. ID.me is a trusted credential service provider selected to support IRS.gov login services.

ID.me uses the latest in identity verification technology to authenticate your identity quickly and easily. Learn more about ID.me and the IRS verification process at Sign In or Create a New Account.

If you have an existing account with the IRS, use your Secure Access username and password and enter the security code as part of the multi-factor authentication (MFA) process. If you have an existing account with ID.me from a state government or federal agency, you may use your email and password and complete MFA.
