## SECTION 3 — How to Change or Correct a Name on a United Airlines Ticket

A name on your airline ticket must match your government-issued identification exactly. Even a small typo can prevent you from boarding. United Airlines has a clearly defined name correction policy that distinguishes between minor corrections and full legal name changes.

### Minor Name Corrections

A minor name correction typically involves fixing a typo, transposed letters, or a missing middle name. United Airlines allows minor corrections of up to 3 characters for most fare types. These corrections can usually be made without a fee if caught early.

To request a minor name correction, call United Airlines at **1-866-284-3014** and have your booking confirmation number and the correct spelling of your name (as shown on your ID) ready.

### Legal Name Changes

A legal name change — for example, after marriage or divorce — requires documentation such as a marriage certificate or court order. United Airlines will update your ticket name to reflect your legal name, but the corrected name must exactly match the name on your new government-issued ID.

### Step-by-Step: How to Correct Your Name on a United Airlines Ticket

1. Gather your booking confirmation number and the misspelled name on the ticket.

2. Locate your government-issued ID showing the correct name.

3. Call United Airlines at **1-866-284-3014** and explain you need a name correction.

4. Provide the agent with your booking reference and the correct spelling.

5. If a legal name change, submit the required documentation as requested by the agent.

6. Confirm the corrected itinerary and check that the new name appears correctly on your updated booking confirmation.

**Important:** United Airlines does not allow full passenger name transfers (i.e., completely changing the passenger to a different person). Name changes are limited to corrections or legal name updates. If you need to transfer a ticket to someone else, you will need to cancel and rebook.

### Name Correction for International Flights

For international travel, name accuracy is even more critical because it affects visa and passport verification. If you discover a name error on an international booking, call **1-866-284-3014** immediately. Do not wait until the day of departure.
