Binance Passport Middle Name: Which KYC Field Should You Fill In?
Where you enter the middle name depends on what is written in your passport's "Given Name" field. The core principle is: the spelling on the Binance KYC page must exactly match the name sequence in the machine-readable zone (MRZ) of your passport. Any discrepancy will cause an automatic mismatch rejection.

1. First, understand the name structure on your passport
A standard passport data page typically has two key fields:
Surname / Family Name: Usually appears on a separate line as its own field.
Given Name: This field may contain multiple words separated by spaces. Your middle name can appear in two ways:
Case A: Middle name is part of the "Given Name" field
If your passport shows the Given Name as "John Michael", then "Michael" is simply part of your first name, not a separate field.
Case B: Middle name has its own dedicated field
Some countries (e.g., Thailand) explicitly list a "Middle Name" field on their IDs or passports. In that case, fill it in exactly as shown.
2. Copy exactly as written on the passport – do not split or merge
Binance's identity verification page typically provides two input boxes: "Given Name / First Name" and "Surname / Last Name". A few regional versions may have a separate "Middle Name" field.
Step 1: Check the content of your passport's Given Name line
What to do: Look at what is written in the "Given Name" field on your passport.
How to do it:
If the Given Name field shows only "John": Enter "John" in the first name box.
If the Given Name field shows "John Michael": Enter "John Michael" in its entirety into the first name box. Do not enter only "John", and do not move "Michael" into a middle name field (unless the page has a dedicated middle name box and your passport also lists a separate middle name).
When is it considered complete?: The name you entered on the Binance page matches the string in the passport's "Given Name" field character by character.
Step 2: Cross-check against the machine-readable zone (MRZ) format
What to do: Verify the entry method using the name concatenation pattern in the MRZ at the bottom of your passport.
How to do it: The second line of the passport MRZ contains the name data. The format is "surname
When is it considered complete?: The name order you filled in matches the logic of the MRZ breakdown.
Prerequisite: You have a valid passport, and the data page is clearly legible.

3. Potential impact of a middle name
Case A: Binance page has a dedicated "Middle Name" field
If there is a specific "Middle Name" box but your passport's Given Name is only "John" (no middle name), leave the middle name box blank. Do not enter nicknames, English names, or any name that does not appear on your passport. Doing so could affect future transactions.
Case B: No dedicated "Middle Name" field
In this scenario, if your passport's Given Name contains multiple words, enter all of them into the first name box. Binance's KYC verification system requires the name string to match the document exactly. A mistake will lead to outright rejection.
Risk warning: KYC information cannot be changed at will once submitted and confirmed. Entering the wrong name may cause identity verification to fail. If you discover a mistake after approval, you must go through the formal "Update Identity Verification" process for re-review; during this period, your account may have trading functions restricted.
After these checks, how do you confirm you filled it in correctly?
Once filled in, compare the name on the page with your passport's Given Name field character by character, ensuring that spaces and sequence are exactly the same. If the system requires names in pinyin or English only, make sure the spelling matches your passport, not a Chinese name arrangement. Confirm everything is correct before submitting. If the review is rejected and returned, check whether the page indicates "Information does not match the ID", then correct it based on the prompt – note that you usually cannot edit directly while in "pending review" status; you must wait for the return before you can re-edit.
