AFAB stands for “Assigned Female at Birth.” It is a term used to describe the sex designation given to a person when they were born, usually based on physical characteristics observed at birth.

AFAB does not automatically describe someone’s current gender identity.
For example, an AFAB person may identify as a woman, man, nonbinary person, or another gender.
The term focuses on the sex designation made at birth rather than how someone identifies later in life.
You may see AFAB in social media posts, online communities, healthcare discussions, and conversations about gender.
Understanding the difference between sex assigned at birth and gender identity helps explain why the term is used.

What Does AFAB Mean?
AFAB stands for “Assigned Female at Birth.”
It refers to the sex designation given to someone when they were born. In many cases, this designation is made by observing physical characteristics, particularly genital anatomy.
The term is often used because a person’s sex designation at birth and gender identity are not necessarily the same thing.
For example, an AFAB person could identify as:
- A woman
- A man
- Nonbinary
- Another gender identity
AFAB is therefore a descriptive term about a person’s designation at birth, not a statement about their current gender.
AFAB Meaning in Simple Words
In simple English:
AFAB means someone was designated female when they were born.
It does not tell you exactly how that person identifies today.
For example:
“She is AFAB.”
This means she was assigned female at birth, but if the person identifies as a woman, the term may not be especially important in ordinary conversation.
Another example:
“The group is for AFAB nonbinary people.”
Here, AFAB provides additional information about the person’s birth designation alongside their current gender identity.
AFAB Full Form
The full form of AFAB is:
Assigned Female at Birth
The phrase is generally preferred over “female at birth” in contexts where the distinction between birth designation and gender identity matters.
The related term is:
AMAB = Assigned Male at Birth
These terms are often used together when discussing gender identity and experiences.
AFAB Meaning in Texting
AFAB is not typical texting slang like LOL, BRB, or SMH.
Instead, it is an abbreviation commonly used in online conversations involving:
- Gender identity
- Transgender communities
- Nonbinary communities
- Healthcare
- LGBTQ+ discussions
- Online support communities
For example:
“I’m AFAB and nonbinary.”
The person is saying that they were assigned female at birth and currently identify as nonbinary.
Because AFAB can involve personal information, it is best not to assume someone’s AFAB/AMAB status unless they have chosen to share it.
AFAB Meaning on Social Media
On platforms such as TikTok, Instagram, Reddit, and other online communities, AFAB may appear in conversations about gender identity.
Examples include:
“AFAB nonbinary experiences”
or:
“Things I wish I knew as an AFAB person.”
The term can help people describe experiences related to how they were treated or perceived based on their sex designation at birth.
However, AFAB does not mean “woman.”
An AFAB person can have many different gender identities.
How to Pronounce AFAB
AFAB is usually pronounced by saying each letter:
“A-F-A-B”
It is generally not pronounced as a single word.
For example:

Origin of AFAB
AFAB developed as part of terminology used to distinguish sex assigned at birth from gender identity.
The phrase became increasingly common in transgender, nonbinary, medical, academic, and online communities.

The purpose of these terms is to describe someone’s birth designation without automatically assuming their current gender.

| AMAB | Assigned Male at Birth | Designated male at birth |
Neither term automatically tells you someone’s current gender identity.

AFAB vs. Female
These terms are related but are not always interchangeable.
Female can refer to biological sex or sex characteristics, depending on the context.
AFAB specifically describes the designation made at birth.
For example:
“AFAB person”
focuses on the person’s sex designation at birth.
The term can be useful when discussing experiences where birth assignment is relevant while avoiding assumptions about someone’s current gender identity.
AFAB vs. Woman
AFAB does not mean woman.
A woman may be AFAB, but not every AFAB person identifies as a woman.
This distinction is especially important when discussing transgender and nonbinary people.
For example:
AFAB = assigned female at birth
Woman = a gender identity
These describe different concepts.
